Description

The invention relates to computing, in particular, to a system for quantifying the level of flight safety of aircraft of an airline according to their operation, implementing the use of new information technologies in assessing the safety of flights of civil aviation aircraft.

The existing methodology for assessing flight safety (BP), based on the analysis of statistics on aircraft accidents and incidents and other events with aircraft (aircraft), unfortunately, cannot solve the issues of assessing the level of flight safety and airworthiness, which are determined and normalized by probabilistic criteria (for example, the probabilities of occurrence of special situations, the degree of their danger, etc.) [3].

In accordance with [3], flight safety is the property of the air transport system to carry out air transportation without threatening the life and health of people, and flight safety is the probability of a catastrophic situation not occurring in flight when adverse factors are manifested.

As unfavorable factors, aviation rules AP-25 [4] consider failure conditions (functional failure, type of system failure), external influences (phenomena) and errors, where:

- a failed state (functional failure, type of system failure) is understood as an inoperative state of the system as a whole, characterized by specific violations of its function, regardless of the causes of this condition;

- external influences (phenomena) - events whose source of origin is not related to the aircraft structure (such as atmospheric conditions, turbulence, thunderstorm, wind shear, condition of the runway, etc .;

- Errors - events involving improper actions by the crew or maintenance personnel.

Flight safety depends, first of all, on the airworthiness of the aircraft, interpreted in the form of a certain characteristic determined by the principles provided for and implemented in the aircraft structure and its flight qualities, allowing safe flight under the expected conditions and with established operating methods.

The airworthiness indicators are the probabilities of special situations in flight due to a failure condition. At the same time, a special situation is the situation that arose in flight as a result of exposure to adverse factors or their combination and leading to a decrease in flight safety.

In accordance with the requirements of AP-25, four classes of special situations are considered: a catastrophic situation, an emergency situation, a difficult situation, and complication of flight conditions:

- a catastrophic situation (CS) is a special situation for which it is accepted that when it occurs, the prevention of death is almost impossible;

- emergency situation (AS) - a special situation characterized by a significant deterioration in performance and / or achievement (exceeding) of maximum limits or physical fatigue, or such a load on the crew that you can no longer rely on the fact that he will fulfill his tasks accurately or completely;

- a difficult situation (SS) - a special situation characterized by a noticeable deterioration in performance and / or one or more parameters going beyond operational limits, but without reaching limit limits, or a decrease in the crew’s ability to cope with adverse conditions (situation that has arisen) due to an increase in working load, and because of conditions that reduce the effectiveness of the crew;

- complication of flight conditions (UP) - a special situation that causes a slight deterioration in performance (without reaching them beyond operational or extreme limits) or a slight increase in the workload of the crew.

Operational restrictions - conditions, modes and parameter values, the deliberate going beyond which is not permissible during operation.

Limit restrictions - restrictions on the flight mode, beyond which it is not permissible under any circumstances.

In [3], for the quantitative assessment of the flight safety level according to operation data, the concept of frequency (statistical probability assessment) Q ^{* for} occurrence of special situations per hour of field was first introduced as the ratio of the number of special situations of one subclass of the class of special situations to the total flight time of one type:

where n _OS - the number of special situations of one subclass of the class of special situations, T _Σ - the total flight of aircraft of the same type.

In addition, for each class of special situations, limit (threshold) standard values for the probabilities of occurrence of special situations were developed (Table 1), which allows you to quickly monitor the level of flight safety of aircraft according to changing data on their operation.

Moreover, the introduction of standard total probabilities of occurrence of special situations allows you to track the impact on flight safety of each individual special situation that occurs in flight.

Hence the task of automating the quantitative assessment of the flight safety level of civil aviation aircraft according to their operation.

Known systems that could be used to solve the problem [1, 2].

The first of the known systems comprises data reception and storage units connected to control and data processing units, search and selection units connected to data storage and display units, the synchronizing inputs of which are connected to the outputs of the control unit [1].

A significant drawback of this system is the impossibility of solving the problem of updating data stored in memory in the form of relevant documents, simultaneously with solving the problem of delivering the contents of these documents to users in real time.

Another system is known, containing a central processor module, the inputs of which are connected to the memory modules and to the data preparation and input modules, and the outputs are connected to the corresponding memory modules, the data processing module, the information inputs of which are connected to the outputs of the corresponding memory modules, the synchronizing inputs are connected to control outputs of the central processor module, and the output of the module is the information output of the system [2].

The last of the above technical solutions is closest to the described.

Its disadvantage lies in the low speed of the system, due to the fact that the implementation of analytical data processing procedures is carried out by searching the entire database, which, when the database is large, inevitably leads to unreasonably large time spent on obtaining analytical estimates.

The purpose of the invention is to increase the system performance by eliminating data search over the entire volume of the server database and localizing the search only at the reference (base and relative) database addresses, corresponding airline identifiers, aircraft types, as well as class numbers of special situations and their subclasses.

To organize the storage of operational data for all types of airline aircraft, the system matches the airline code with a certain starting address of the database memory, called the base, relative to which the operational data of each type of its aircraft are shifted. In this case, the offset value corresponds to the aircraft type code, and the identifiable address of the aircraft operation data of one type, obtained by adding this offset to the base address of the airline operation data, is called the relative address of the aircraft operation data of the same type.

Within the relative address of the data on the operation of aircraft of one type there is also information on the parameters of the classes of special situations, the address of each of which is already shifted relative to the relative address of the data on the operation of aircraft of one type. In this case, the offset value corresponds to the code of the class number of special situations. By adding the offset corresponding to the code of the class number of special situations to the relative address of the data on the operation of aircraft of one type, we obtain the relative address of the parameters of the class of special situations issued to the address input of the system database server.

The server reads the parameters of the class of special situations at the exposed address and sends them to the information input of the system.

The parameters of the class of special situations read from the server database are represented by the codes: code of the number of the first class of special situations; code number of the second class of special situations; code number of the third class of special situations; code number of the fourth class of special situations; code for the total aircraft raid of one type; code for the number of special situations of the requested class that arose during the specified total raid, code for the number of subclasses in this class of special situations; code for the dimension of the memory page of the server database.

Processing the accepted parameters of the class of special situations begins with the procedure for checking the number of special situations of the class in question for equality to zero.

If the code for the number of incidents of the requested class of special situations is equal to zero, the system gives the user a signal “Operation of aircraft without incidents” and the code number of the analyzed class of special situations to the user's workstation.

After that, the system checks whether all classes of exception situations are processed by the system. If not all classes are processed, then the system goes to the module where the number of the next class of special situations and the address of the parameters of this class are generated, which are issued to the address input of the database server.

As soon as the code for the number of incidents of the processed class of special situations turns out to be non-zero, the system, issuing the total plaque code to the information input of the database server, proceeds to call the subroutine for calculating the inverse of the total plaque.

The server calculates the value of the reverse plaque and sends its code to the input of the module, which recognizes the branch of calculating the probability of occurrence of special situations by the number of subclasses of the processed class, accepted as the class parameters.

If the number of subclasses of the processed class is equal to one, then control is transferred to the decision-making module on the level of flight safety by the signal probabilities of special situations classes, and if the number of subclasses of the processed class is more than one, then control is transferred to the decision-making module on the level of flight safety according to the total class probabilities special situations.

Let the number of subclasses of the processed class of special situations be equal to one. In this case, in the decision-making module on the flight safety level according to the signal probabilities of the classes of special situations, the code of the signal probability of occurrence of special situations is calculated and compared with the standard code of the signal probability of the class in question.

In this case, the following information is issued to the user's workstation: code of the signal probability of the class of special situations under consideration, developed by the system according to the class parameters; the code of the class of special situations under consideration and the signal “Safety level meets / does not satisfy regulatory requirements”.

After that, in the control module for completing the analysis procedure for an array of classes of special situations, an analysis is made of the completion of the survey and the processing of all classes of special situations of the requested type of aircraft.

If not all classes have been analyzed and processed, then go to the address selection module for the class of special situations, where a new class of special situations and the address of its parameters are generated.

If the number of subclasses of the processed class is more than one, then control from the recognition module of the branch of the procedure for calculating the probability of occurrence of special situations is transferred to the decision-making module on the level of safety of flights according to the total probabilities of classes of special situations, where the code of the total probability of occurrence of special situations is calculated and compared with the normative code total probability of the class in question.

In this case, both the code of the total probability of the class of special situations considered by the system according to the class parameters and the code of the class of special situations considered, as well as the signal “Flight safety level satisfies / does not meet regulatory requirements” are issued to the user's workstation.

If the code of the total probability of the class in question, developed by the system according to the parameters of this class, satisfies the regulatory safety requirements, the system transfers control to control the completion of the processing procedure for all classes of special situations.

If the code of the total probability of the class in question, developed by the system according to the parameters of this class, does not meet the regulatory safety requirements, the system transfers control to the selection module for the base address of the parameters of the subclasses of the class of special situations, where the base address of the parameters of the subclasses of the class of special situations is generated, starting with which in the memory of the system database contains the parameters of all subclasses of the class of special situations under consideration, and is issued to the address input of the server system database.

The server reads the parameters of the first subclass of the class in question at the exposed address and sends the code of the number of the class of special situations and the code of the number of special situations of the first subclass of the class of special situations to the information input of the signal probability identification module of the subclasses of the special situations class.

In this module, the signal probability of occurrence of special situations is calculated, which is sent both to the system user workstation and to the decision-making module on the level of flight safety by the signal probabilities of subclasses of the class of special situations, where it is compared with the standard signal probability of the class of special situations under consideration with signal generation “The level of flight safety satisfies / does not satisfy regulatory requirements” and transferring it to the user's workstation.

In addition, each of these signals goes further to the module that controls the procedure for viewing all subclasses of the class of special situations under consideration.

If not all subclasses of the considered class of special situations have been viewed yet, control is again transferred to the selection module for the base address of the parameters of the subclasses of the class of special situations, where the address of the next subclass of the class in question is formed, which is again set to the address input of the system database server.

The server polls its database and reads the parameters of the next subclass of the class of special situations from the exposed address and sends them to the signal probability identification module of subclasses of the class of special situations to calculate the signal probability of the occurrence of special situations in the subclass of the class of special situations, etc.

The described process of generating the addresses of the parameters of the subclasses of the considered class of special situations and the server polling its database for the exposed addresses with the transfer of their contents to the system will continue until the signal probabilities of all subclasses of the class of special situations are generated and checked for compliance with regulatory requirements.

As soon as the signal probability of occurrence of special situations of the last subclass of the considered class of special situations is developed and processed, the system transfers control to the module that controls the processing of the parameters of all classes of special situations set at the user's request.

To start the system, the user at his workplace generates a request codogram, which indicates the airline code, aircraft type code, code for the number of emergency situations requested for analysis, the code for the initial (starting) class of emergency situations, as well as codes for the standard signal and total probabilities of occurrence special situations in the classes under consideration.

For definiteness, let the first class with the code 001 be indicated in the codogram for definiteness as the starting class of special situations, and the number of classes of emergency situations requested for analysis is four, i.e. the system should analyze all classes of special situations, starting with the first. Then the initial system user codogram will receive the form of Table 2:

The generated codogram from the workstation of the user of the system is fed to the information input 15 of the system, fed to the information input 53 of the identification module 1 of the base address of the airline’s aircraft operation data and entered into the register 45 by a synchronizing pulse supplied to the synchronizing input 54 of the module 1 from the synchronizing input 19 of the system .

The airline code from the output 56 of register 45 is fed to the input of the decoder 46. The decoder 46 decrypts the airline code and generates at one of its outputs a high potential supplied to the corresponding inputs of elements 48-50 I. For definiteness, we assume that the high potential from the output of the decoder 46 is open element 50 And one input.

The synchronizing pulse from the input 19 of the system, passing through the input 54 of module 1, is delayed by the delay element 51 for the response time of the register 45 and the decoder 46 and enters through the element 50 And opened through one input and to the read input of a fixed cell of read-only memory (ROM) 47.

A fixed cell in ROM 47 stores the code of the base address of the airline’s aircraft operation data, starting from which the server’s data on the operation data of all types of airline aircraft is stored in the server’s database. At the same time, for each type of aircraft, a separate memory area is allocated in the server database memory, the address of which is offset from the base address by a certain amount corresponding to the identifier code of the aircraft type.

Therefore, the aircraft type code from the output 69 of module 1 is sent to the information input 93 of the module 2 for identifying the relative address of the aircraft operation data of one type and is fed to the input of the decoder 85. The decoder 85 decodes the aircraft type code and generates a high potential at one of its outputs the corresponding inputs of the elements 88-90 I. For definiteness, suppose that the high potential from the output of the decoder 85 will open the element 90 And one input.

In this case, the synchronizing pulse from the output of the delay element 51, delayed by the delay element 52 while reading the contents of the fixed cell of the ROM 47 of module 1 and the operation of the decoder 85 of module 2, is sent from the output 80 of module 1 to the synchronization input 95 of module 2 and enters through the open one by one input element 90 And to the read input of a fixed cell of a read-only memory (ROM) 86. In a fixed cell of a ROM 86 a code is stored for the offset address of the aircraft operating data of the type whose identifier was applied to input 93 of the decoder 85 module 2.

This code from the output of the ROM 86 is fed to one information input of the adder 87, to the other information input 94 of which the code of the base address of the airline operating data from the output 68 of module 1 is supplied.

According to the clock pulse from the input 95 of the module 2, delayed by the delay element 91 for the time of reading the fixed cell of the ROM 86, in the adder 87, the relative address of the aircraft operating data of one type corresponding to the identifier supplied to the input 93 of the decoder 85 of the module 2 is formed.

The code of the starting (in our case, the first) class of special situations from the information output 70 of module 1 is sent to the information input 114 of module 3 of the selection of the address of the parameters of the class of special situations and is fed to the input of the counter 100.

According to the synchronizing pulse received at the synchronizing input 116 of module 3 from the output 97 of module 2 after a delay by the delay element 92 for the response time of the adder 87 of module 2, the start (first) class of special situations code is entered into the counter 100 of module 3 and fed to the input of the decoder 102. Decoder 102 decodes the code for the start class of special situations and generates at one of its outputs a high potential supplied to the corresponding inputs of elements 105-107 I. For definiteness, we assume that the high potential from the output of the decoder torus 102 will be opened element 105 And one input.

A clock pulse from the input 116 of module 3 passes the OR element 108, is delayed by the delay element 110 for the response time of the counter 100 and the decoder 102, and enters through the element And 105, which is open one at a time, to the read input of a fixed cell of read-only memory (ROM) 103. In a fixed cell ROM 103 stores an offset code for the address of the parameters of the first class of special situations with respect to the address of the aircraft operating data of one type.

The code for shifting the address of the parameters of the first class of special situations, read from the ROM 103, is supplied to one information input of the adder 104, to the other information input 115 of which from the output 96 of module 2 a code of the relative address of the aircraft operation data of one type is supplied.

According to the synchronizing pulse from the output of the delay element 110, delayed by the delay element 111 for the time of reading the fixed cell of the ROM 103, in the adder 104, the relative address of the parameters of the start class of special situations is generated, according to which the information about the parameters of the requested first class of special situations is stored in the server database .

Formed in the adder 104, the address of the parameters of the starting class of special situations is fed to the input of the register 101, where it is entered by the synchronizing pulse from the output of the delay element 111 after the delay by the delay element 112 for the duration of the operation of the adder 104.

The same pulse from the output of the delay element 112 is delayed by the delay element 113 for the time in which the code 101 contains the relative address of the parameters of the start class of special situations issued to the address output 23 of the system, and from the output 32 of the system it enters the input of the first channel of the server interrupt.

With the arrival of this impulse, the server switches to the subprogram for polling the contents of its database at the address generated on the address output 23 of the system and issuing the read parameters of the start class of special situations to the information input 16 of the system.

The parameters of the start class of special situations read from the server database are represented by codes: 001 - the code of the number of the first class of special situations; 010 - number code of the second class of special situations; 011 - code number of the third class of special situations; 100 - number code of the fourth class of special situations; T _Σ is the code value of the total raid of aircraft of the same type; n _OS is the code of the number of special situations of the starting class that arose during the raid T _Σ m _subcl - the code of the number of subclasses in the starting class of special situations; 4 Kbytes is the code for the dimension of the memory page (Table 3).

The parameters of the starting class of emergency situations, read from the server database, from the information input 16 of the system go to the information input 138 of the register 135 of module 5 for registering the parameters of the class of emergency situations, where they are entered by the synchronizing pulse of the server, which arrives at the synchronizing input 139 of the register 135 from the input 20 of the system.

The code for the number of special situations of the requested class from the output 142 of the register 135 of module 5 is fed to the information input 161 of the comparator 155 of the module 6 for selecting the class of special situations without incident, the other input of which is grounded. In this case, the server synchronizing pulse from the synchronizing input 20 of the system after the delay by the delay element 137 for the time of entering the code of the class of special situations parameters into the register 135 from the output 150 of the module 5 is supplied to the synchronizing input 162 of the comparator 155 of the module 6 and polls the codes at its inputs.

If the code for the number of incidents of the requested class of special situations, supplied to the input 161 of the comparator 155, is equal to zero, then the output 163 of the comparator 155 produces a signal that opens the element 156 And one input.

The synchronizing pulse from the input 162 of module 6 is delayed by the delay element 159 for the response time of the comparator 155, passes through the I 156 element, which is open at one input, and the signal “Operation of aircraft without incidents” is received from the output 166 of the module 6, which is output from the signal output 35 of the system to AWP system user.

The same signal from the output of element 156 AND passes through the AND elements of group 158 the code number of the analyzed class of special situations to the information output 165 of module 6, which goes to the information input 160 of module 6, and from the information output 28 of the system is issued to the user's workstation.

In addition, the same signal from the output 166 of module 6 is supplied to the synchronizing input 359 of the module 14 for monitoring the completion of the analysis of the array of classes of special situations, the OR element 356 passes, and enters the counting input of the counter 354, increasing its content by one.

The counter 354 counts on an accrual basis the number of analyzed classes of special situations of the system, each time outputting its contents to one input of the comparator 355, to the other input 358 of which from the information output 71 of module 1 a code of the total number of requested classes of special situations equal to four is supplied in our case.

According to the clock pulse from the output of the OR element 356, delayed by the delay element 357 for the increment time of the counter 354, the comparator 355 compares the codes supplied to its inputs, generating a signal at one of its outputs.

Since only the first one was recorded in the counter, corresponding to only one processed class of special situations, the signal will be generated at its output 364, which from the output 367 of module 14 will return to the initial state all those modules of the system that participated in processing the analyzed class of special situations with zero incidents.

In our case, the signal from the output 367 of the module 14 goes to the installation input 140 of the module 5, passes the OR element 136 and goes to the installation input of the register 135, resets its contents to zero and thereby prepares it for a new operation cycle.

The same signal from the output 367 of module 14 also goes to the counting input 117 of module 3, from where, firstly, the OR element 109 passes and enters the installation input of the register 101, resets its contents to zero and thereby prepares it for a new operation cycle.

Secondly, the same signal from the input 117 of the module 3 is fed to the counting input of the counter 100 and increments it, thereby forming in the counter 100 the code number of the next (second) class of special situations.

The code for the number of the second class of special situations generated in the counter is fed to the input of the decoder 102. The decoder 102 decrypts the code of the next class of special situations and generates at one of its outputs a high potential arriving at the corresponding inputs of the elements 105 - 107 I. For definiteness, we assume that the high potential from the output of the decoder 102 will be opened element 106 And one input.

Thirdly, the same signal from the input 117 of module 3 passes the OR element 108, is delayed by the delay element 110 for the response time of the counter 100 and the decoder 102, and enters through the AND element 106 open through one input and to the read input of a fixed cell of read-only memory (ROM) 103. In a fixed cell of the ROM 103, a code for shifting the parameters of the generated new class of special situations is stored with respect to the data address of the operation of aircraft of the same type.

The code for shifting the parameters of a new class of special situations, read from the ROM 103, is supplied to one information input of the adder 104, to the other information input 115 of which, from the output 96 of module 2, a code of the relative address of the aircraft operation data of one type is supplied.

According to the synchronizing pulse from the output of the delay element 110, delayed by the delay element 111 for the time of reading the fixed cell of the ROM 103, the relative address of the parameters of the second class of special situations is generated in the adder 104.

Formed in the adder 104, the address of the parameters of the second class of special situations is fed to the input of the register 101, where it is entered by the synchronizing pulse from the output of the delay element 111 after the delay by the delay element 112 for the duration of the operation of the adder 104.

The same pulse from the output of the delay element 112 is delayed by the delay element 113 for the time of entering into the code register 101 the relative address of the parameters of the new class of special situations issued to the address output 23 of the system, and from the output 32 of the system is input to the first channel of the server interrupt.

With the arrival of this impulse, the server switches to the subprogram for polling the contents of its database at the address generated on the address output 23 of the system and issuing the read parameters of a new (second) class of special situations to the information input 16 of the system.

The parameters of a new class of special situations, read from the server database, from the information input 16 of the system go to the information input 138 of register 135 of module 5, where they are entered by the synchronizing pulse of the server, which goes to the synchronization input 139 of register 135 from the synchronization input 20 of the system.

With the issuance of the code for the number of special situations of a new class from the information output 142 of module 5 to the information input 161 of module 6 by the server clock pulse coming to the system clock input 20, the procedure for processing the parameters of the generated new (second) class of special situations begins.

If the code of the number of special situations of the new class also turns out to be zero, then the entire described procedure for issuing from the signal output 35 of the system to the AWP a user of the signal system “Operation of aircraft without incidents”, accompanied by the issuance of the code of the class of special situations without incidents from the information output of the 28 will be repeated until all four classes of special situations with zero incidents are processed, or until the code for the number of incidents of the generated new class of special situations (in our case, teh) will not be zero.

If the code for the number of incidents of the third class of special situations, supplied to the information input 161 of the comparator 155 of module 6 from the information output 142 of module 5, does not turn out to be zero, then the output 164 of the comparator 155 produces a signal that opens the element 157 And one input.

In this case, the synchronizing pulse from the input 162 of module 6, delayed by the delay element 159 for the time the comparator 155 operates, passes through the element 157 And open at one input and is fed from the output 167 of the module 6 to the synchronizing input 129 of the register 125 of the module 4 of the call of the subroutine for calculating the return value total plaque, entering into it the code of total plaque received at its information input 128 from output 143 of module 5.

The same pulse from the input 129 of the module 4 is delayed by the delay element 127 for the response time of the register 125 and from the output 33 of the system is fed to the input of the second channel of the server interrupt.

With the arrival of this impulse, the server polls its information inputs and takes from the information output 27 the total plaque code issued from the output 132 of register 125 of module 4 and returns from its database the information in the system input 17 as a code in the form of the code for the inverse of the total plaque.

The code of the reciprocal value of the total plaque read from the server’s database from the information input 17 of the system goes to the information input 196 of register 185 of module 8 for recognizing the branch of the procedure for calculating the probabilities of occurrence of special situations, where it is entered by the server’s synchronizing pulse received at the synchronizing input 197 of register 185 from the synchronizing input 21 systems.

With the same pulse from the synchronizing input 21 of the system, the trigger 186 is set to a single state in which a high potential from the direct output of the trigger 186 is supplied to one information input of the comparator 187, to the other input 195 of which the code of the number of subclasses of the third class of special situations from the output of 144 module 5 is supplied .

According to the synchronizing pulse from the input 197 of module 8, delayed by the delay element 191 for the time of recording the code 185 of the reciprocal of the total plaque value and setting the trigger 186 to a single state, the comparator 187 compares the codes received at its information inputs.

If the code for the number of subclasses of the processed third class of special situations is equal to one, then at the output 193 of the comparator 187 a signal is generated that opens the input element 189 I.

In this case, the synchronizing pulse from the output of the delay element 191, delayed by the delay element 192 for the response time of the comparator 187, passes through the And 189 element open at one input and is supplied from the synchronizing output 201 of module 8 to the synchronizing input 280 of the decision level 10 module 10 according to signal probabilities of classes of special situations.

According to the synchronizing pulse at the input 280 of module 10, the code for the number of special situations of class n _{os of} the third class being processed is supplied to the information input 275 of the multiplier 245 from the information output 142 of the module 5 and is multiplied with the code of the inverse value of the total plaque supplied to the information input 276 of the multiplier 245 from the information output 200 of module 8. The result of multiplication in the form of a signal probability code of the analyzed third class of special situations is supplied from the output of the multiplier 245 to one information input of the comparators 250-253 mode la 10.

The synchronizing pulse from the input 280 of module 10, delayed by the delay element 256 for the response time of the multiplier 245, is fed to the synchronizing inputs of the comparators 246-249 and allows the comparison of the codes supplied to their information inputs.

At the same time, the same number code of the requested third class of special situations is fed from the information output 119 of module 3 to the general information input 271 of the comparators 246-249, while the code number of the first class of special situations is sent to the information input 270 of the comparator 246, to the information input 273 the comparator 247 is supplied with the code number of the second class of special situations, the information code 277 of the comparator 248 is supplied with the code number of the third class of special situations, and the information code 279 of the comparator 249 is supplied with the code of the fourth class number special situations.

According to the synchronizing pulse supplied to the synchronizing inputs of the comparators 246-249 from the output of the delay element 256, the comparators will compare the codes supplied to their inputs. In this case, a signal will be generated at the output of the comparator, which has equal codes at its inputs.

Since in our case the request for the third class of special situations is processed, the same codes will be at the inputs 271 and 277 of the comparator 248, and a signal will be generated at its output 259.

This signal from the output 259 of the comparator 248 allows the comparison of the signal probability codes of the third class of special situations filed to the information inputs of the comparator 252. The signal probability code of the third class of special situations generated by the system and the other information the input 274 of the comparator 252 is the code of the standard (permissible) signal probability for the third class of special situations from the information output 78 of module 1.

If the signal probability code generated by the system according to the parameters of the third class of special situations read from the server database turns out to be less than the standard signal probability of the third class of special situations, then at the output 266 of the comparator 252 a signal is generated that passes the OR element 255 and from the output 284 of module 10 the signal “Flight safety level meets regulatory requirements” is removed, which is output from the system output 38 to the system user workstation.

If the signal probability code generated by the system according to the parameters of the third class of special situations read from the server database turns out to be greater than or equal to the normative signal probability of the third class of special situations, then at the output 265 of the comparator 252 a signal is generated that passes the OR element 254 and from the output 283 module 10, the signal “Flight safety level meets regulatory requirements” is removed, which is output from the system output signal 39 to the user's workstation.

The issuance of each of these signals is accompanied by the issuance of the code of the signal probability of a special situation for the current analyzed class from the system information output 29 and the number code of the current analyzed class of special situations from the system information output 30 to the system user.

In addition, the signal from the output 284 of the module 10 is supplied to the synchronizing input 360 of the module 14, and the signal from the output 283 of the module 10 is supplied to the synchronizing input 361 of the module 14. Next, each of these signals passes the OR element 356 and goes to the counting input of the counter 354, incrementing him. The counter 354 counts on an accrual basis the number of processed classes of special situations and provides its contents to one information input of the comparator 355, to another information input 358 of which the code of the total number of requested classes of special situations from the output 71 of module 1 is four.

According to the clock pulse from the output of the OR element 356, delayed by the delay element 357 for the increment time of the counter 354, the comparator 355 compares the codes supplied to its inputs, generating a signal at one of its outputs.

Since the contents of the counter 354 after increment will be equal to three, i.e. If the code is the total number of all classes of special situations analyzed by the system at the input 358 of the comparator 355, the signal is generated at the output 364 of the comparator 355. This signal from the output 367 of the module 14 is received:

- to the installation input 130 of module 4, the OR element 126 passes through and enters the installation input of the register 125, resets its contents to zero and thereby prepares it for a new operation cycle;

- to the installation input 140 of module 5, the OR element 136 passes and enters the installation input of the register 135, resets its contents to zero and thereby prepares it for a new operation cycle;

- to the installation input 199 of module 8, the OR element 188 passes and enters both the installation input of the register 185, resetting its contents to zero and thereby preparing it for a new operation cycle, and the installation input of the trigger 186, resetting its state to zero.

The same signal from the output 367 of the module 14 is fed to the counting input 117 of the module 3, from where, firstly, the OR element 109 passes and enters the installation input of the register 101, resets its contents to zero and thereby prepares it for a new operation cycle.

Secondly, the same signal from the input 117 of the module 3 is fed to the counting input of the counter 100 and increments it, thereby forming in the counter 100 the code number of the next, fourth, class of special situations.

The code of the fourth class of special situations number generated in the counter is fed to the input of the decoder 102. The decoder 102 decodes the code of the fourth class of special situations and generates at one of its outputs a high potential arriving at the corresponding inputs of the elements 105 - 107 I. For definiteness, we assume that the high potential from the output of the decoder 102 will open the element 107 And one input.

Thirdly, the same signal from the input 117 of module 3 passes through the OR element 108, is delayed by the delay element 110 for the response time of the counter 100 and the decoder 102, and enters through the element 107 open AND open at one input and to the read input of a fixed cell of read-only memory (ROM) 103. In a fixed cell of ROM 103, a code for shifting the parameters of a new, fourth, class of special situations is stored with respect to the data address of the operation of aircraft of the same type.

The parameter shift code of the fourth class of special situations, read from ROM 103, is supplied to one information input of the adder 104, to the other information input 115 of which, from the output 96 of module 2, a code for the relative address of the aircraft operation data of one type is supplied.

According to the synchronizing pulse from the output of the delay element 110, delayed by the delay element 111 for the time of reading the fixed cell of the ROM 103, the relative address of the parameters of the fourth class of special situations is generated in the adder 104.

The address of the parameters of the fourth class of special situations formed in the adder 104 is fed to the input of the register 101, where it is entered by the synchronizing pulse from the output of the delay element 111 after the delay by the delay element 112 for the duration of the operation of the adder 104.

The same pulse from the output of the delay element 112 is delayed by the delay element 113 for the time in which the code 101 registers the relative address of the parameters of the fourth class of special situations issued to the address output 23 of the system, and from the output 32 of the system enters the input of the first server interrupt channel.

With the arrival of this impulse, the server switches to the subprogram for polling the contents of its database at the address generated on the address output 23 of the system, and issuing the read parameters of the fourth class of special situations to the information input 16 of the system.

The parameters of the fourth class of special situations read from the server database from the information input 16 of the system go to the information input 138 of the register 135 of module 5, where they are entered by the synchronizing pulse of the server, which goes to the synchronizing input 139 of the register 135 from the synchronizing input 20 of the system.

With the issuance of the code for the number of special situations of the fourth class from the information output 142 of the module 5 to the information input 161 of the module 6 by the synchronizing pulse of the server supplied to the synchronizing input 20 of the system, the procedure for processing the parameters of the fourth class of special situations begins.

It should be borne in mind that by the start of processing the parameters of the fourth class of special situations, the system fully analyzed and processed all the parameters of only three classes of special situations. A characteristic feature of this state of the system is the contents of the counter 354 of the module 14, equal to three.

Processing the parameters of the fourth class of special situations begins with checking the number of incidents of this class for equality to zero.

If the code for the number of incidents of the fourth class of special situations, supplied to the information input 161 of the comparator 155 of module 6 from the information output 142 of module 5, does not turn out to be zero, then the output 164 of the comparator 155 produces a signal that opens the element 157 And one input.

In this case, the synchronizing pulse from the input 162 of module 6, delayed by the delay element 159 for the duration of the operation of the comparator 155, passes through the And 157 element open by one input and from the output 167 of the module 6 is fed to the synchronizing input 129 of the register 125 of the module 4 of the call of the subroutine for calculating the return value total plaque, entering into it the code of total plaque received at its information input 128 from output 143 of module 5.

The same pulse from the input 129 of the module 4 is delayed by the delay element 127 for the response time of the register 125 and from the output 33 of the system is fed to the input of the second channel of the server interrupt.

With the arrival of this impulse, the server polls its information inputs and takes from the information output 27 the total plaque code issued from the output 132 of register 125 of module 4 and returns from its database the information in the system input 17 as a code in the form of the code for the inverse of the total plaque.

The code of the reciprocal value of the total plaque read from the server’s database from the information input 17 of the system goes to the information input 196 of register 185 of module 8 for recognizing the branch of the procedure for calculating the probabilities of occurrence of special situations, where it is entered by the server’s synchronizing pulse received at the synchronizing input 197 of register 185 from the synchronizing input 21 systems.

With the same pulse from the synchronizing input 21 of the system, the trigger 186 is set to a single state in which a high potential from the direct output of the trigger 186 is supplied to one information input of the comparator 187, to the other input 195 of which the code of the number of subclasses of the class of special situations from the output of 144 module 5 is supplied.

According to the synchronizing pulse from the input 197 of module 8, delayed by the delay element 191 for the time of recording the code 185 of the reciprocal of the total plaque value and setting the trigger 186 to a single state, the comparator 187 compares the codes received at its information inputs.

If the code for the number of subclasses of the requested fourth class of special situations is greater than one, then a signal is generated at the output 194 of the comparator 187, which opens 190 I through one input.

In this case, the synchronizing pulse from the output of the delay element 191 after the delay by the delay element 192 for the response time of the comparator 187 passes through the And 190 element open at one input and is supplied from the synchronizing output 202 of module 8 to the synchronizing input 240 of the decision-making module 9 about the safety level total probabilities of classes of special situations.

According to a synchronizing pulse at the input 240 of module 9, the code of the number of special situations of the fourth class supplied to the information input 235 of the multiplier 205 from the information output 142 of the module 5 is multiplied with the code of the inverse value of the total plaque supplied to the other information input 236 of the multiplier 205 from the information output of the module 200 8. The result of the multiplication in the form of a code of the total probability of the analyzed fourth class of special situations is supplied from the output of the multiplier 205 to one information input of the comparators 210-213 of module 9.

The synchronizing pulse at the input 240 of module 9, delayed by the delay element 216 for the response time of the multiplier 205, arriving at the synchronizing inputs of the comparators 206-209, allows the comparison of the codes supplied to their information inputs.

At the same time, the same code of the fourth class of special situations is supplied from the information output 119 of module 3 to the general information input 231 of comparators 206-209, while the code of the number of the first class of special situations is fed to the information input 230 of the comparator 206, and to the information input 233 of the comparator 207 the code of the number of the second class of special situations is supplied, the code of the number of the third class of special situations is supplied to the information input 237 of the comparator 208, and the code of the number of the fourth class of special situations is fed to the information input 239 of the comparator 209.

According to the synchronizing pulse supplied to the synchronizing inputs of the comparators 206-209 from the output of the delay element 216, the comparators will compare the codes supplied to their inputs. In this case, a signal will be generated at the output of the comparator, which has equal codes at its inputs.

Since the request of the fourth class of special situations is being processed by the system at the moment in question, then the numbers of the fourth class of special situations will appear at the inputs 231 and 239 of the comparator 209, and a signal will be generated at the output 220 of the comparator 209.

This signal from the output 220 of the comparator 209 allows the comparison of the codes of the total probabilities of the fourth class of special situations submitted to the information inputs of the comparator 213. The code of the total probability of the fourth class of special situations generated by the system is supplied to one information input of the comparator 213 from the output of the multiplier 205, and to the other information the input 238 of the comparator 213 is the code of the standard (permissible) total probability for the fourth class of special situations from the information output 75 of module 1.

If the total probability code generated by the system according to the parameters of the fourth class of special situations read from the server database turns out to be less than the standard total probability of the fourth class of special situations, then the output 228 of the comparator 213 generates a signal that passes through the OR element 215 and from the output 244 of the module 9 the signal “Flight safety level meets regulatory requirements for the total probability” is removed, which from the signal output 36 of the system is issued to the user's workstation.

If the total probability code generated by the system according to the parameters of the fourth class of special situations read from the server database turns out to be greater than or equal to the standard total probability code of the fourth class of special situations, then a signal is generated at the output 227 of the comparator 213, which passes the OR element 214 OR from the output 243 of module 9, the signal “Flight safety level does not meet the regulatory requirements for the total probability” is removed, which is issued from the signal output 37 of the system to the user's workstation.

In this case, the code of the total probability of a fourth-class emergency situation generated by the system from the information output 241 of module 9 is sent to the information output 25 of the system, and the code of the fourth class of special situations from the information output 242 is sent to the information output 26 of the system, from where these codes are issued to the workstation system user.

In addition, the signal of satisfying the flight safety level with regulatory requirements from the output 244 of module 9 is fed to the synchronizing input 363 of module 14, the OR element 356 passes, and enters the counting input of the counter 354, increasing its content by one information input to the comparator 355 and thereby fixing the completion of the analysis and processing of parameters of the fourth class of special situations.

The synchronizing pulse from the output of the OR element 356, delayed by the delay element 357 for the time the counter 354 is triggered, is fed to the synchronizing input of the comparator and allows the comparison of codes supplied to its information inputs.

Since the other information input 358 of the comparator 355 also contains a code number of the fourth class of special situations received from the information output 71 of module 1, a signal corresponding to the equality of codes at the inputs of the comparator will be generated at the output 365 of the comparator 355. This signal is immediately sent to the installation counter input 354, returning it to its original state.

The same signal from the output 368 of the module 14 is supplied:

- to the installation input 131 of module 4, the OR element 126 passes and enters the installation input of the register 125, resets its contents to zero and thereby prepares it for a new operation cycle;

- to the installation input 118 of module 3, from where it enters the installation input of the counter 100, returning it to its original state, and, having passed the OR element 109, enters the installation input of the register 101, resets its contents to zero and thereby prepares it for a new cycle work;

- to the installation input 55 of module 1, from where it enters the installation input of the register 45, resets its contents to zero and thereby prepares it for a new operation cycle;

- to the installation input 141 of module 5, the OR element 136 passes and enters the installation input of the register 135, resets its contents to zero and thereby prepares it for a new operation cycle;

- to the installation input 198 of module 8, the OR element 188 passes and enters both the installation input of the register 185, resetting its contents to zero and thereby preparing it for a new operation cycle, and the installation input of the trigger 186, resetting its state to zero.

When the system generates a signal “The flight safety level does not satisfy regulatory requirements for the total probability”, a search begins for subclasses of the analyzed class of special situations with unacceptable signal probabilities.

For this, the signal from the output 243 of module 9 is fed to the synchronizing input 178 of module 7 for selecting the base address of the parameters of the subclasses of the class of special situations and is fed to the synchronizing input of the adder 171, allowing the summation of the codes on its information inputs. In this case, an address offset code corresponding to the code of the class number of special situations is supplied to the information input 176 of the adder 171 from the information output 120 of the module 3, and a code corresponding to the size of the server database memory page is sent to the other information input 177 of the adder 171 from the information output 145 of the module 5 .

The code obtained as a result of summation is the base address of the parameters of the subclasses of the fourth class of special situations under consideration, starting from which the parameters of all its subclasses are stored in the memory of the server database.

The generated base address of the parameters of the subclasses of the fourth class of special situations is fed to the information input of the counter 170, where it is entered by the synchronizing pulse from the synchronizing input 178 of module 7, delayed by the delay element 173 for the operation time of the adder 171.

The same impulse from the output of the delay element 173 passes through the OR element 172, is delayed by the delay element 174 for the time that the base address code of the parameters of the subclasses of the analyzed fourth class of special situations entered into the code counter 170 is issued from the information output 182 of the module 7 to the address output 24 of the system and from the output 34 of the system is input to the first channel of the server interrupt.

With the arrival of this impulse, the server switches to the subprogram for polling the contents of its database at the address generated on the address output 24 of the system and issuing the read parameters of the first subclass of the analyzed fourth class of special situations to the information input 18 of the system.

The parameters of the first subclass of the analyzed fourth class of special situations, read from the server’s database, are fed from the information input 18 of the system to the information input 290 of the register 285 of the module 11 for identifying the signal probabilities of the subclasses of the class of special situations, where they are entered by the synchronizing pulse of the server, coming to the synchronizing input 292 of the register 285 s synchronizing input 22 of the system.

The parameters of the first subclass of the analyzed fourth class of special situations read from the server database and accepted into register 285 are represented by codes (Table 4):

The code of the number of special situations of the first subclass of the analyzed fourth class of special situations from the output 296 of the register 285 is fed to one information input of the multiplier 286, the other information input 291 of which is supplied with the code of the reciprocal of the total plaque from the output 200 of module 8.

According to the clock pulse at the input 292 of the module 11, delayed by the element 298 for the duration of the operation of the register 285, the codes supplied to its inputs are multiplied in the multiplier 286.

The product obtained in the multiplier 286, identified as the code of the signal probability of occurrence of special situations of the first subclass of the analyzed fourth class of special situations, is output from the output 298 of the module 11 both to the information output 31 of the system, from where it is output to the user's workstation and to the information input 323 of module 12 making decisions about the level of flight safety by signaling probabilities of subclasses of the class of special situations.

Information input 323 of module 12 is a common information input of comparators 304-307. In this case, the code of the normative signal probability of the second class of special situations from the information output 77 of module 1 is sent to the other information input 322 of the comparator 304; the code of the normative signal probability of the first class of special situations is sent to the other information input 326 of the comparator 305 information input 328 of comparator 306 is supplied with the code of the normative signal probability of the third class of special situations from information output 78 of module 1, and to another information input 330 compar torus 307 is fed code regulatory signal probability fourth grade with exception of the information output module 79 1.

The code of the analyzed fourth class of special situations from the information output 297 of module 11 is fed to the common information input 325 of comparators 300-303 of module 12. At the other information input 324 of comparator 300, the code of the number of the first class of special situations is supplied from information output 146 of module 5, to another information input 327 of the comparator 301, the code number of the second class of special situations is supplied from the information output 147 of module 5, the code of the number of the third class of special situations with information th output unit 5 148, on the other information input 331 of comparator 303 is fed a fourth code class number of special situations with data output 149 of the module 5.

Since the current analyzed class of special situations, supplied to the common information input 325 of the comparators 300-303, is the fourth, therefore, according to the synchronizing pulse from the output of the delay element 288, delayed by the delay element 289 for the response time of the multiplier 286, a signal appears at the output of 313 of the comparator 303, having on its information inputs equal codes corresponding to the code of the fourth class number of special situations.

The signal from the output 313 of the comparator 303 compares the signal probability code of the first subclass of the fourth class of special situations, generated by the system according to the number of incidents and fed to the information input 323 of comparators 304-307, with the regulatory code of the signal probability of the fourth class of special situations, sent to the information input 330 of the comparator 307.

If the signal probability code of the first subclass of the considered fourth class of special situations, developed by the system according to the number of incidents, turns out to be less than the code of the standard signal probability of the fourth class of special situations, then the output 321 of the comparator 307 generates a signal that passes through the OR element 309 and from the output 334 of module 12 the signal “Flight safety level meets regulatory requirements for signal probability” is removed, which is issued from the signal output 40 of the system to the user's workstation.

In addition, the signal from the output 334 of module 12 is supplied to the synchronizing input 347 of module 13, the OR element 342 passes, and enters the counting input of the counter 340, increasing by one its content, which is supplied each time to one information input of the comparator 341. To another information input 346 comparator 341 is supplied with the code of the number of subclasses of the current analyzed class of special situations from the information output 144 of module 5.

Counter 340 counts on an accrual basis the number of subclasses of the current analyzed (in our case fourth) class of special situations processed by the system.

According to the synchronizing pulse from the output of the OR element 342, delayed by the delay element 343 for the increment time of the counter 340, the comparator 341 compares the codes received at its information inputs and generates a signal at one of its outputs.

Since only the first unit corresponding to the first subclass of the current analyzed fourth class of special situations was entered into counter 340, for any number of subclasses of the analyzed class of special situations greater than one, the code supplied to the information input 346 of comparator 341 will be more than one and, therefore, a signal will be generated at the output 344 of the comparator 341.

This signal from the output 349 of module 13 is supplied to the installation input 293 of module 11, the OR element 287 passes, and enters the installation input of register 285, resets its contents to zero and thereby prepares it for a new operation cycle.

The same signal from the output 349 of the module 13 is fed to the counting input 179 of the module 7 and is fed to the counting input of the counter 170, increasing its content by one, thereby forming the address of the parameters of the next (already second) subclass of the current analyzed fourth class of special situations.

The same signal from the counting input 179 of module 7 passes the OR element 172, is delayed by the delay element 174 during the formation in the counter 170 of the parameter address of the next subclass of the analyzed fourth class of special situations, issued from the information output 182 of module 7 to the address output 24 of the system, and from the output 34 of the system is input to the first channel of the server interrupt.

With the arrival of this impulse, the server switches to the subprogram for polling the contents of its database at the address generated on the address output 24 of the system and issuing the read parameters for the next (second) subclass of the analyzed fourth class of special situations to the information input 18 of the system.

This process of generating and reading the addresses of subclasses of the current analyzed class of special situations with the subsequent processing of their parameters will continue until the comparator 307 of module 12 of the signal at its output 320 identifies a subclass of the current analyzed class of special situations with a signal probability greater than or equal to the standard probability the current parsed class.

In this case, the signal from the output 320 of the comparator 307 passes the OR element 308 and the signal “Flight safety level does not meet the regulatory requirements for signal probability” is received from the output of the module 12, which is issued to the system user AWP from the signal output 41 of the system.

In addition, the signal from the output 333 of the module 12 is fed to the synchronizing input 348 of the module 13, the OR element 342 passes, and enters the counting input of the counter 340, increasing by one its content, which is supplied each time to one information input of the comparator 341. To another information input 346 comparator 341 is supplied with the code of the number of subclasses of the current analyzed class of special situations from the information output 144 of module 5.

Counter 340 counts progressively the number of subclasses of the current analyzed class of special situations processed by the system.

According to the synchronizing pulse from the output of the OR element 342, delayed by the delay element 343 for the increment time of the counter 340, the comparator 341 compares the codes received at its information inputs and generates a signal at one of its outputs.

If the code for the contents of the counter 340 is less than the code for the number of subclasses of the analyzed class of special situations, the signal will be generated at the output 344 of the comparator 341.

As soon as the last subclass of the analyzed class of special situations is processed, the code of the counter content 340 will be equal to the code of the number of subclasses of the analyzed class supplied to the information input 346 of the comparator. In this case, the signal will be generated already at the output 345 of the comparator 341.

This signal from the output 345 is immediately supplied to the installation input of the counter 340, returning it to its original state and preparing it for work in the next cycle of analysis and processing of parameters of subclasses of the following class of special situations.

The same signal from the output 350 of module 13 is fed to the installation input 180 of module 7 and is supplied to the installation input of the counter 170, returning it to its original state and preparing it for work in the next cycle of analysis and processing of parameters of subclasses of the following class of special situations.

The same signal from the output 350 of module 13 is supplied to the installation input 294 of module 11, the OR element 287 passes, and enters the installation input of register 285, resetting its contents to zero and preparing it, thereby, for a new operation cycle.

The same signal from the output 350 of the module 13 is supplied to the synchronizing input 362 of the module 14, the OR element 354 passes, and enters the counting input of the counter 354, increasing by one its contents supplied to one information input of the comparator 355, to the other information input 358 of which the code the total number of classes of special situations requested by the system, equal to four.

Counter 354 counts cumulatively the number of exception classes that have been processed.

Since we were processing the fourth class of special situations, and the contents of counter 354 were three, the contents of the counter after its increment became four. Therefore, the codes supplied to the information inputs of the comparator 355 match.

In this case, the output 365 of the comparator 355 produces a signal that is immediately fed to the installation input of the counter, returning it to its original state and thereby preparing it for a new operation cycle.

The same signal from the output 368 of the module 14 is supplied:

- to the installation input 131 of module 4, the OR element 126 passes and enters the installation input of the register 125, resets its contents to zero and thereby prepares it for a new operation cycle;

- to the installation input 118 of module 3, enters the installation input of the counter 100, returning it to its original state, and, having passed the OR element 109, enters the installation input of the register 101, resets its contents to zero and thereby prepares it for a new operation cycle ;

- to the installation input 55 of module 1, from where it enters the installation input of the register 45, resets its contents to zero and thereby prepares it for a new operation cycle;

- to the installation input 141 of module 5, the OR element 136 passes and enters the installation input of the register 135, resets its contents to zero and thereby prepares it for a new operation cycle;

- to the installation input 198 of module 8, the OR element 188 passes and enters both the installation input of the register 185, resetting its contents to zero and thereby preparing it for a new operation cycle, and the installation input of the trigger 186, resetting its state to zero and thereby preparing him for a new cycle of work.

Thus, the introduction of new nodes and modules and new structural connections has significantly improved system performance by eliminating data retrieval across the entire system server database.
