ENERGY PROTECTION DEVICE FOR AN AIRCRAFT

摘要

Energy protection device for an aircraft.;The device (1) comprises units (12, 14, 15) for automatically deactivating an energy protection function, if a return of the aircraft to an operational flight domain is detected after the activation of this protection function, and for automatically managing an autothrust (2), if at least one of the following conditions is satisfied: a relaxing of a control member is detected, and the angle of attack of the aircraft is below a predetermined threshold.

1. An energy protection method for an aircraft which is provided with at least one engine, an autothrust, and at least one piloting control member, said method consisting:
a) in automatically and repetitively monitoring, during a flight of the aircraft, a plurality of aircraft data, including an angle of attack of the aircraft, so as to be able to detect a trigger situation, for which conditions for triggering an energy protection are satisfied; b) if a trigger situation is detected, in automatically activating a protection function consisting in automatically engaging said autothrust if it is not already engaged and in automatically controlling said engine for it to supply a maximum thrust, and in implementing a monitoring consisting in automatically and repetitively monitoring aircraft parameters, so as to be able to detect a return of the aircraft to a predetermined operational flight domain; and c) if a return of the aircraft to said operational flight domain is detected, in automatically deactivating the protection function,wherein said method consists, in the step c), in automatically deactivating the protection function, upon the detection of a return of the aircraft to said operational flight domain, only if at least one of the following conditions is also satisfied:
a relaxing of the control member is detected, the relaxing of the control member being detected when the control member is in a position below a first predetermined nose-up threshold; and the angle of attack of the aircraft is below a predetermined threshold.
