Definitions
- the invention lies in the field of man-machine interfaces of a civilian or military air traffic control station. More specifically, the field of the invention relates to devices for warning or alerting a controller that an aircraft will perform a landing at altitude.
- a flight level is often called landing or a CFL, whose acronym means in the English terminology used in aeronautics "Cleared flight Level”.
- CFL landing or a CFL
- the crew defines a level of cruise that it wishes to join.
- the controller may need to deliver the CFL requested by the crew, that is to say generally at the cruising level of an aircraft, but the controller may also assign a CFL less than the requested level by the pilot for security reasons.
- the controller when another aircraft wishes to reach and fly a certain landing, the controller must wait to see the evolution of the situation before responding favorably to the request.
- the controller should regularly check the situation to see if he can, or not, give permission to climb higher or lower than the current situation of the aircraft. But it is also possible, for reasons of coordination given the organization of the control, that the controller must request authorization from the adjacent sector if the requested level is outside his area of responsibility. A sector is called a cut of the airspace to distribute the workload on several controllers.
- air traffic controllers allocate space per zone, each zone comprising a given perimeter and an altitude slice. As the aircraft change slices, the controllers coordinate to track an aircraft crossing a landing.
- the air traffic controller may be required to give an intermediate level of flight to the aircraft crew.
- this intermediate level is not the one desired by the crew, it allows the controller to have time to coordinate.
- the controller In order to prevent the aircraft from making an intermediate landing at this altitude level which is not the desired one, the controller must send a new altitude setpoint before the aircraft reaches its intended intermediate level so that the new setpoint is taken into account.
- the only way is to periodically monitor the altitude of the aircraft.
- the controller must therefore monopolize much of his attention to the surveillance of an aircraft at the expense of other actions. It can perform this monitoring from the radar tracks on a control screen or from the display indicating the tracking of the vertical trajectories of aircraft included in a portion of the space.
- An object of the invention is to overcome the aforementioned drawbacks.
- An object of the invention is in particular to relieve the air controller by means of a device for generating an alarm when the aircraft is approaching a landing or an altitude level at which a decision of the controller must be made .
- the subject of the invention is a device for assisting the monitoring of climbs and descents of aircraft intended for air traffic controllers, comprising:
- ⁇ data receiving means emitted by an aircraft comprising at least its position in space and possible requests transmitted by the crew;
- ⁇ a display for displaying the trajectory of an aircraft performing a maneuver in order to reach a first level and altitude
- ⁇ means for giving an authorization to achieve a second level of altitude the crew of the aircraft.
- the device comprises an alarm manager configurable according to at least one flight condition of the aircraft calculated from the first altitude level for issuing an alarm at a time when the condition is met.
- the condition may be an altitude threshold remaining to be traveled to the first altitude level, the alarm being triggered when the threshold value is crossed by the aircraft.
- the condition can be a predefined duration before reaching the first altitude level, the alarm being triggered when the time remaining for the aircraft to reach the first altitude level is less than the predefined duration.
- the display generates an indicator on the trajectory of the aircraft indicating the moment when the alarm will be triggered.
- the alarm is a visual alarm displayed on the air traffic controller display or an alarm is an audible alarm.
- the alarm is displayed in superposition of the trajectory of the aircraft at the symbol representing the aircraft.
- FIG. 1 represents an air control screen indicating the position of certain aircraft, their flight plan and an alarm indicator according to the invention.
- Figure 2 shows an air control screen indicating a visual alarm around the symbol of the monitored aircraft.
- FIG. 3 shows a vertical section of the flight plan and a marker indicating to the controller the presence of an alarm.
- FIG. 4 represents a vertical section of the modified flight plan after receiving a command from the controller.
- FIG. 1 represents a visual display screen enabling an air traffic controller to monitor a portion of the airspace that corresponds to his sector. As the aircraft change slices, the controllers coordinate to track an aircraft crossing a landing.
- an aircraft 1, noted AE1 in block 2 follows a flight plan 3. It flies at an altitude of 17000 feet and must reach an altitude of 20000 feet. This information is given in block 2 so as to inform the controller of the trajectory followed by the aircraft 1. For example, in FIG. 1, the aircraft 1 raises a landing at 17000 feet to a landing at 20000 feet.
- a second aircraft 4, noted AE2 in a second block 5 flies at a fixed altitude of 38000 feet according to its flight plan 6.
- the controller thus visualizes the trajectories of different aircraft whose flight plans cross his sector.
- the invention makes it possible to generate an alarm at a time determined by a marker 7 represented on the flight plan 3.
- the marker 7 is an indication calculated by the system and indicating the point at which the alert will be triggered. This indication is visible only from the controller in charge of the sector. It indicates the presence of an alarm which aims to inform the controller of the imminence of the arrival of the aircraft at its next landing which in the example of Figure 1 at 20000 feet.
- the invention makes it possible to generate an alarm when the aircraft approaches its next landing, the latter being inputted by the controller.
- this alarm can be triggered a number of seconds before reaching the next landing of the aircraft, for example 60 seconds before reaching it.
- the alarm can be triggered at a certain altitude before reaching the next landing, for example 1500 feet before the landing.
- the alarm will be triggered at 18500 feet before reaching the landing of 20000 feet.
- Figure 2 shows the same view but a few minutes later.
- the aircraft 1 approaches its landing at 20000 feet, it passes through the point indicated by marker 7 in this example to 1500 feet below the landing at 20000 feet, ie at an altitude of 18500 feet.
- the symbol 1 representing the aircraft is surrounded by a second symbol 20 representing a halo.
- the visual alarm captures the attention of the controller to drive him to act to communicate a command to the pilot.
- the controller can then send a command to the pilots indicating that the aircraft can continue its climb to the second stop, the second stop being the landing defined after the next landing. For example, it may be a second landing at 30000 feet, without marking the next landing at 20000 feet.
- the instruction can be transmitted orally by the controller to the crew.
- the alarm may for example be a sound / audible alarm emitting a specific sound to warn the controller of the imminence of his arrival at the next level mentioned on the flight plan of the aircraft.
- the invention also makes it possible to indicate in the controller's calendar the moment at which the alarm will be triggered.
- the controller can at any time consult his diary and see how much time he has left to assess whether it is possible or not to continue the climb or descent without the aircraft flying to the next level. This moment can also be displayed on the flight plan by a graphic symbol.
- An advantage of the invention is that this alarm allows the controller to focus on the other tasks. It no longer needs to periodically monitor the ascent or descent of the aircraft, because the alarm will indicate the moment at which it must make a decision.
- An advantage of the invention is to be able to overcome unnecessary bearings provided in the flight plan and which may not be stolen by an aircraft wishing to continue its climb.
- FIG. 3 represents the vertical section of a flight plan 36 in a coordinate system whose axes represent, in ordinate, the altitude, denoted ALT, and in abscissa the time, denoted t.
- the flight plan 36 is generally programmed on the ground by the pilots to perform a flight corresponding to a given mission.
- the aircraft 1 starts a first climb phase making it possible to reach a first landing 32 'after crossing a waypoint 32.
- the aircraft in theory continues to a new departure point. passage 33 to start a second climbing phase.
- the aircraft then climbs to a landing 34 'passing through a waypoint 34 before reaching another waypoint 35.
- the next bearing is the bearing 32 'and the second bearing is the bearing 34' with the definitions specified above.
- the marker 7 indicates when the alarm recorded by the controller will be generated to remind him that at that moment he will eventually have to send a direction to the crew of the aircraft 1.
- FIG. 4 represents the case of FIG. 3 when the aircraft crosses point 7 of its flight plan. It is not very far from reaching its point of passage 32 and the controller considers that nothing prevents the climb of the aircraft directly to the landing 34 '.
- the controller sends a command to the crew of the aircraft 1 indicating that it can continue its climb directly to the second level.
- the crew redefines a flight plan sequence that suppresses the level 32 '.
- a new flight plan 36 ' is thus generated and the crossing point 32 becomes a simple point 40 located on the flight path of the aircraft.
- This solution has the advantage of saving flight time, simplifying the management operations of aircraft flying bearings, including this maneuver reduces the number of steps.
- the invention reduces fuel consumption throughout the flight.
- the invention also applies to downhill bearings according to the same principle.
