- FIG. 6 represents additional steps of the method for managing speed constraints of a flight plan of an aircraft
- the invention presents a management method 1, represented in FIG. 1, of speed constraints of a flight plan of an aircraft capable of proposing a complete flight profile that can be applied to the CLIMB flight phases, CRUISE, DESCENT and APPROACH.
- the management method 1 aims to propose a complete profile to allow the aircraft to fly it automatically and autonomously, and to facilitate the operation of this complete profile by an operator once in flight.
- the management method 1 is implemented for speed constraints of the AT type, representing a speed to be respected, AT OR BELOW representing a maximum speed to be respected or AT OR ABOVE representing a minimum speed to be respected.
- the management method 1 also allows consideration of a WINDOW-type constraint representing a speed window between a minimum speed and a maximum speed as a combination of an AT OR BELOW speed constraint and an AT speed constraint OR ABOVE.
- the method 1 for managing speed constraints of an aircraft flight plan comprises the following steps:
- An identification step (05) of a current flight phase of the aircraft the flight phase can be one of the following phases: CLIMB, CRUISE, DESCENT and APPROACH.
- the speed profile establishes a behavior of the aircraft with respect to a speed setpoint, the speed setpoint being a function of the flight phase In progress.
- the speed profile then represents a speed target to be respected by the aircraft at any point of the flight plan according to speed constraints present during the flight phases.
- the Mach speed profile establishes a behavior of the aircraft with respect to a Mach setpoint, the Mach setpoint being a speed setpoint transcribed into an equivalent Mach number the Mach setpoint therefore also being a function of the flight phase in progress.
- the Mach speed profile defines the Mach target to be reached by the aircraft at any point of the flight plan as a function of the speed constraints present during the flight phases.
- a step of determining a Cross-Over altitude 50 The Cross-Over altitude is the altitude of passage from a servo-control of the aircraft according to the speed profile in CAS to a servo-control according to the profile of Mach speed of the speed profile. In other words, the Cross-Over altitude is the optimized crossing altitude between the CAS speed profile and the Mach speed profile,
- step 30 for determining a criterion for the end of applicability of the speed profile and of the Mach speed profile.
- the management method 1 identifies the next flight in the flight plan and repeats the steps mentioned above, namely the steps of determining a speed profile 10, determining a Mach 20 speed profile, determining a Cross-Over altitude 50 and determining an end of applicability criterion for the next flight phase until the entire flight plan of the aircraft is completed, that is to say until the landing of the aircraft. 'aircraft.
- the profile of a flight phase of an airplane conventionally comprises two portions, a first portion where the servo-control setpoint is a CAS speed and a second portion, from a certain altitude called Cross-Over (or XOVER), for which the speed setpoint is a Mach.
- the CAS speed setpoint is determined during the construction of the speed profile in order to control the behavior and the speed of the aircraft during the first portion where the servo-control setpoint is linked to a CAS speed.
- the Mach setpoint is determined during the construction of the Mach speed profile in order to control the behavior of the aircraft during the second portion of the flight phase where the feedback setpoint is linked to a Mach.
- the Cross-Over XOVER altitude therefore represents the altitude where a specific speed becomes a specific Mach number or vice versa.
- the Cross-Over altitude therefore represents the optimized or adequate crossing altitude between a CAS speed profile and a Mach speed profile.
- the speed profile determination step 10 may comprise, as represented in FIG. 2, a step of constructing a first CAS speed profile 100.
- the speed setpoint according to the first speed profile is then constructed on the basis of aircraft performance. More specifically, the speed setpoint according to the first speed profile is based on the assumption that the speed constraints are compatible with the performance of the aircraft.
- the aircraft following the first speed profile 102, only respects AT OR BELOW BBB and CCC constraints and deliberately ignores AT OR ABOVE AAA1 and AAA2 constraints, judged to be generated in accordance with the performance of the aircraft. . Consequently, the speed constraint AT OR ABOVE AAA1 , which represents a minimum speed lower than the first speed profile 102 calculated, at the level of the constraint AAA1 , is then respected. Conversely, the speed constraint AT OR ABOVE AAA2, which is greater than the first speed profile 102 on passing the speed constraint AT OR ABOVE AAA2 of the aircraft following the first speed profile 102, is then not not respected. This information of non-compliance with a speed constraint can then be referred to the operator so as to warn him of this irregularity in maintaining the speeds of the flight phase of the aircraft.
- the step of determining the speed profile 10 can include a step of constructing a second CAS speed profile 120, represented in FIG. 4, by adapting the sharing of energy between kinetic and potential.
- the speed setpoint according to the second speed profile then allows the aircraft to comply with all of the speed constraints AT and AT or ABOVE and AT or BELOW during the flight phase by modifying the ratio between kinetic energy, namely horizontal speed, and potential energy, i.e. vertical speed, and increasing kinetic energy at the expense of potential energy.
- the aircraft, respecting the second speed profile is then able to gain or lose altitude with a lower vertical gradient.
- the determination of the modified ratio and the distribution between kinetic energy or horizontal speed and potential energy or vertical speed can be carried out during a step of calculation of the modified ratio 124, represented in FIG. 4, by various known methods such as the dichotomy, the calculation brute force or through a numerical estimator.
- the second speed profile 120 makes it possible to obtain a flight instruction that respects all of the speed constraints, whether they are minimum or maximum.
- first, second and third CAS speed profiles can be exercised according to a backward calculation method called BACKWARD.
- the BACKWARD method allows, for the DESCENT phase, the calculation of a reverse speed profile, where the speed constraints follow one another starting from the approach speed of the aircraft and accelerating against the constraints. in constraints up to the start of descent speed.
- the BACKWARD method presents the calculation of a reference speed profile that the aircraft must follow.
- the aircraft follows, via the flight management system, a speed profile calculated according to the FORWARD method, in real time, allowing the aircraft, during the DESCENT or APPROACH phase for example, to take into consideration factors external to the aircraft such as actual weather conditions.
- the FMS flight management system of the aircraft generally operating according to a FORWARD calculation method different from the BACKWARD method
- the management method 1 also allows the enslavement of this method for the benefit of the BACKWARD method according to the invention.
- the aircraft can, in certain cases, reach altitudes where the servo-control of the aircraft must be done via a Mach setpoint and not by the intermediary of a speed instruction risking harming the integrity of the aircraft. Therefore, the management process 1 , can construct different strategies making it possible to control the aircraft according to a CAS or Mach speed instruction in a given applicability zone.
- the step of determining the Mach speed profile 20 comprises, as represented in FIG. 5, a step of constructing a first Mach speed profile 200.
- the Mach setpoint according to the first Mach speed profile is determined according to a predefined Mach. More specifically, this construction of the first Mach 200 speed profile is based on the characteristics and performance of the aircraft since the Mach setpoint according to the first speed profile requires compliance with an economic Mach or MACH ECON representing the economic Mach of aircraft flight.
- the economic Mach corresponds to the speed at which, in the environment where the Mach setpoint prevails, the aircraft exhibits optimized performance by taking into consideration various performance parameters such as the speed of the aircraft or the power deployed. in comparison with cost parameters such as aircraft fuel consumption.
- the Mach setpoint constructed will then respect the economic Mach MACH ECON until the end of applicability criterion determined beforehand during the determination step 30.
- This first Mach 200 speed profile then allows the aircraft to respect in a first the speed setpoint defined during step 10 up to the Cross-Over altitude XOVER and then to respect as the only setpoint, the economic Mach MACH ECON of the aircraft.
- the first Mach speed profile can result in non-compliance with speed constraints after reaching the Cross-Over altitude XOVER allowing passage from a speed setpoint to a setpoint of Mach.
- a constant Mach does not generally mean having a constant CAS speed due to the change in altitude and therefore in temperature and pressure. Nevertheless, this non-compliance can be announced to the aircraft operator who can judge this irregularity as acceptable for the operation of the aircraft.
- the step of determining the Mach 20 strategy can include a step of constructing a second Mach 220 speed profile allowing the aircraft to comply with all of the speed constraints AT and AT or ABOVE. in the given area of applicability.
- the Mach setpoint according to the second Mach speed profile is then constructed with knowledge of the strongest speed constraint. More specifically, the second Mach speed profile aims to allow the aircraft to respect all of the speed constraints in the given applicability zone of the aircraft, similarly to the construction of the second speed profile 120. Consequently, the Mach setpoint corresponds to the strongest constraint of the flight phase previously determined in the CAS speed setpoint and slaves the aircraft according to this strongest CAS speed constraint converted into a Mach number.
- the Mach setpoint according to the second Mach speed profile can then be a conversion of this CAS speed setpoint into a Mach number.
- the Mach speed profile takes precedence over the CAS speed profile by no longer imposing a servo-control of the CAS speed but a servo-control of the Mach of the aircraft.
- the step of determining the Cross-Over altitude 50 XOVER allowing the switchover from the CAS speed setpoint to the Mach setpoint may comprise, as represented in FIG. 5, a step of calculating a first Cross-Over altitude 520.
- the first Cross-Over altitude XOVER1 is then calculated according to a first speed constraint CAS, which can be, by way of preferential example, the strongest speed constraint AT or AT or ABOVE, the economic ECON speed of the aircraft and the economic Mach of the aircraft.
- a first speed constraint CAS which can be, by way of preferential example, the strongest speed constraint AT or AT or ABOVE, the economic ECON speed of the aircraft and the economic Mach of the aircraft.
- the first Cross-Over altitude can be calculated according to the following formula:
- XOVER1 represents the first Cross-Over altitude
- CAS max represents the strongest speed constraint
- CAS ECON represents the economic speed ECON of the aircraft
- MACH ECON represents the economic Mach of the aircraft.
- the step of determining the Cross-Over altitude 50 can also comprise a step of calculating a second altitude, or chosen altitude, of Cross-Over 540 allowing switching between CAS speed setpoint and Mach setpoint.
- the second Cross-Over altitude XOVER2 is then the chosen altitude enabling the aircraft to respect the speed setpoint CAS of the speed profile before switching to a Mach setpoint.
- the second altitude of Cross-Over XOVER2 can be calculated according to the following formula:
- XOVER2 represents the selected Cross-Over altitude and MACH 2 represents the second Mach speed profile.
- the step for determining the Cross-Over altitude 50 XOVER may include a step for calculating a third Cross-Over altitude 560 allowing the switch between CAS speed setpoint and Mach setpoint.
- the third altitude of Cross-Over XOVER3 is then between the altitude of a second predefined constraint AT or AT or ABOVE, which can be, by way of preferential example, the highest speed constraint AT or AT or ABOVE, or the altitude of the economic speed ECON if the economic speed ECON is greater than the higher speed constraint AT or AT or ABOVE, and the altitude corresponding to the higher speed between the Mach equivalent to the second speed constraint CAS AT or AT or ABOVE, namely, as a preferred example, greater speed constraint, at an imposed flight level CRZ and the economic Mach ECON MACH.
- the third altitude of Cross-Over XOVER3 can be calculated according to the following formula:
- MACH 2CRZ represents the second Mach speed profile at the imposed CRZ flight level.
- the determination step 30 makes it possible to determine, a first end of applicability criterion 320, making it possible to end the CAS speed setpoint and the Mach speed profile, may correspond to an end of the flight phase , such as the end of a CLIMB phase or a CRUISE phase.
- the determination step 30 makes it possible to determine a second end of applicability criterion 340 corresponding to reaching a predefined altitude such as the Cross-Over XOVER altitude.
- a phase of flight for example, of the CLIMB type
- the Cross-Over altitude XOVER imposing the passage to a Mach setpoint to allow the servo-control of the aircraft coincides with the Maximum altitude reached by the aircraft during a CLIMB phase.
- the determination step 30 makes it possible, as an additional variant, to determine a third criterion 360, representing a point of the flight plan.
- the last point of the flight plan reflecting the end of a departure procedure in the CLIMB phase can be considered as the third end of applicability criterion making it possible to end the CAS speed instruction and the Mach speed profile.
- the third end of applicability criterion has the advantage of being able to maintain the CAS speed setpoint and/or the Mach setpoint beyond the flight phase.
- the third end of applicability criterion makes it possible to maintain the strongest speed constraint beyond the CLIMB flight phase and to also have it applied in the following CRUISE phase. This scenario can occur when the aircraft's cruising level is low, for example in the case of a relatively short flight to a nearby airport, or when flight envelope restrictions limit the cruising altitude. .
- the end of applicability criterion advantageously makes it possible to end the speed profile being applied in order to allow the transition to a new speed set point directly linked to the next flight phase, the current speed profile being the CAS speed profile or the Mach speed profile.
- the method 1 for managing speed constraints can also comprise a step of removing a speed constraint 70.
- an AT OR ABOVE speed constraint is applicable from the point with which it is associated and, from likewise, an AT constraint becomes a minimum speed from the point to which it is associated. Consequently, once the constraint has been implemented, it is no longer possible to delete it easily since the associated point has just been sequenced and therefore has disappeared from the displayed flight plan.
- the deletion step 70 makes it possible to delete this speed constraint despite the absence of the point with which it is associated.
- this step of removing a speed constraint 70 is independent of the other steps of the management method 1 and automatically leads to a reinitialization of the management method 1 and of the step of determination of a speed profile 10.
- the step of removing a speed constraint 70 can be initialized following the step of determining the end of applicability criterion or precede the step of identifying 05 of the current flight phase leaving the freedom to an operator to decide on the impact of any speed constraint on the flight plan of the aircraft.
- the method for managing speed constraints can include an additional step of adjusting the speed 80 of the aircraft with respect to a speed constraint of the next flight phase. This is particularly the case during the transition from a CRUISE phase to a DESCENT phase of the aircraft with the appearance of a first speed constraint in the DESCENT phase higher, or even significantly higher, than the speed of the aircraft. in the CRUISE phase.
- the management method 1 can allow the aircraft, via the speed adjustment step 80, to adjust its speed with respect to this first speed constraint of the following phase, or DESCENT, by forcing the maintenance of the next highest speed constraint even once the end of applicability condition has been reached for the current flight phase, i.e. the CRUISE phase.
- This situation can arise, for example, in the case of a low cruise.
- the aircraft when the aircraft begins the next flight phase, namely the DESCENT phase, the aircraft maintains a high speed in accordance with the highest speed constraint of the previous flight phase, the CRUISE phase, in order to limit the speed gradient between the two flight phases and to ensure a relevant transition from the CRUISE phase to the DESCENT phase.
- the method 1 for managing speed constraints comprises a step of maintaining speed 60 during the current flight phase. More specifically, the maintenance step 60 imposes a maintenance speed or speed imposed on the aircraft until an event leading to the cancellation of this maintenance of the speed of the aircraft.
- the maintenance step 60 can impose a maintenance speed on the aircraft up to a speed constraint or up to an indicative speed.
- the maintaining step 60 makes it possible to maintain the speed of the aircraft up to a speed constraint of the DESCENT phase.
- the holding step 60 makes it possible to manage this CRUISE-DESCENT transition by suppressing any deceleration and/or acceleration deemed useless by the flight operator, complicating the flight phase and particularly the CRUISE-DESCENT transition and considerably increasing fuel consumption. aircraft fuel during the flight phase.
- the maintenance step 60 can also maintain a speed imposed on the aircraft directly in the DESCENT phase, for example, until an event canceling this maintenance.
- the holding step 60 makes it possible to effectively manage the transition from a flight phase in progress to the following flight phase such as for example the CRUISE-DESCENT transition but also the CLIMB-CRUISE transition.
- the management method 1 also includes a step 65 for monitoring the speed constraints when the aircraft is going through a DESCENT phase or an APPROACH phase. More precisely, the monitoring step 65 allows the storage of the speed constraints AT OR ABOVE and the speed indicators generated by the BACKWARD method in order to allow the respect of the speed constraints and the speed indicators by the FORWARD method of the system of aircraft flight management. It thus becomes possible to enslave and align the FORWARD method of the flight management system planning the flight plan with respect to the reference of the BACKWARD method and therefore to preserve in a more stable manner the time predictions and the consumption of aircraft for example.
- the management method 1 may include a step 90 of displaying speed constraints during the flight phase. More precisely, this display step 90 makes it possible to memorize and display the speed constraints of the aircraft, such as for example the highest speed constraint AT or AT OR ABOVE potentially greater than the economic speed.
- This display is particularly relevant in the case cited above of the presence of a first speed constraint AT or AT OR ABOVE in a DESCENT phase while the aircraft is in CRUISE phase. Thus, the display of this first constraint warns the operator upstream.
- the invention also provides a computer program product comprising code instructions making it possible to perform the steps of the management method 1 when said program is executed on a computer.
- the embodiments of the invention can be implemented by various means, for example by hardware ('hardware'), software, or a combination thereof.
- routines executed to implement the embodiments of the invention may be referred to herein as "computer program code” or simply “program code”.
- Program code typically includes computer-readable instructions which reside at various times in various memory and storage devices in a computer and which, when read and executed by one or more processors in a computer, cause the computer to perform the operations necessary to perform the operations and/or elements specific to the various aspects of the embodiments of the invention.
- the computer-readable program instructions for carrying out the operations of the embodiments of the invention may be, for example, assembly language, or else source code or object code written in combination with one or several programming languages.
- the method for managing speed constraints thus has the advantage of making it possible to automatically determine, depending on the speed constraints taken into account, namely for example the constraints linked to the integrity of the aircraft directly in the case of the first CAS speed profile, or even the speed constraints applicable during the flight phase traveled in the case of the second CAS speed profile, a pair of CAS speed profile and Mach speed profile applicable to the aircraft on the flight phase flown.
- This automatic determination is advantageously done without manual action on the part of the flight operators, thus freeing them from a tedious implementation that is costly in time and energy.
- the invention therefore makes it possible to greatly reduce the pilot's load during the flight phases where speed constraints may appear. [0082] In addition, the invention makes it possible, through the automation of the management of these speed constraints and the construction of a speed profile, to inform the pilot of the "successful" or "failed" status of these constraints. of speed.
- the invention also guarantees the pilot that in “managed” mode, the aircraft automatically respects any binding speed constraint. Finally, the invention makes it possible to visualize when a speed constraint is no longer applied, whether because it has been sequenced according to one of the chosen criteria, or because it has been removed by the crew.
