Piloting device designed to be integrated into a preexisting aircraft
A piloting device arranged to be integrated in a pre-existing aircraft that includes original systems comprising both a flight control system and an autopilot system is distinct from and autonomous relative to the original systems and includes a positioning unit and a control unit. The positioning unit is arranged to produce positioning data for the pre-existing aircraft. The control unit is arranged to perform a geofencing function from the positioning data produced by the positioning unit and to produce an alternative piloting setpoint for the pre-existing aircraft. The alternative piloting setpoint is adapted to supplement both a manual piloting setpoint produced by a pilot of the pre-existing aircraft via the flight control system and also an autopilot setpoint produced by the autopilot system.
1. A piloting device arranged to be integrated in a pre-existing aircraft that comprises original systems comprising both a flight control system and an autopilot system, the piloting device being mechanically separate from and autonomous relative to the original systems and comprising:
a positioning unit arranged to produce positioning data for the pre-existing aircraft; and
a control unit arranged to perform a geofencing function from the positioning data produced by the positioning unit and to produce an alternative piloting setpoint for the pre-existing aircraft, the alternative piloting setpoint being adapted to supplement both a manual piloting setpoint produced by a pilot of the pre-existing aircraft via the flight control system and also an autopilot setpoint produced by the autopilot system.
2. The piloting device according to claim 1 , wherein the alternative piloting setpoint is adapted to pilot the pre-existing aircraft when the pre-existing aircraft is in an emergency situation belonging to a predefined list of emergency situations, the predefined list comprising a failure of the autopilot system, a failure of the pilot of the pre-existing aircraft, and a situation in which the pre-existing aircraft is going towards a predefined prohibited area.
3. The piloting device according to claim 2 , wherein geographical coordinates of predefined prohibited areas are stored in the control unit, and wherein the control unit is arranged to produce the alternative piloting setpoint in such a manner that the pre-existing aircraft follows a path serving to avoid the aircraft penetrating into the predefined prohibited areas.
4. The piloting device according to claim 2 , wherein the control unit is arranged to produce the alternative piloting setpoint in such a manner as to pilot the pre-existing aircraft in the event of the pilot being incapacitated during takeoff of the pre-existing aircraft, and when the speed of the pre-existing aircraft is greater than a predetermined speed above which takeoff can no longer be interrupted.
5. The piloting device according to claim 1 , wherein the control unit has two dissimilar channels each presenting architecture of the COMMON type.
6. The piloting device according to claim 1 , wherein the positioning unit comprises an inertial measurement unit, a satellite positioning device having one or more antennas, and an air data computer.
7. The piloting device according to claim 1 , wherein the alternative piloting setpoint can be a controlled crash setpoint seeking to limit the consequences of an inevitable crash of the pre-existing aircraft.
8. The piloting device according to claim 7 , wherein the piloting device is arranged to cross check information contained in map databases with characteristics of the pre-existing aircraft in such a manner as to define an optimum crash area in which the controlled crash setpoint is to cause the pre-existing aircraft to crash.
9. A pre-existing aircraft including the piloting device according to claim 1 .
