ABSTRACT:
A system for protecting an aircraft in cruising flight against excessive load factors when a vertical gust of wind occurs is disclosed. The system has a pitch-attitude flight control system (21) which is under the control of a pilot of the aircraft, an automatic pilot (26), a switch (25) allowing the aerodynamic pitch-attitude control surfaces (22) of the aircraft to be controlled either by the flight control system (21) or by the automatic pilot (26), and a protection system (31) capable of acting on the switch (25) to disconnect the automatic pilot (26) and switch on the flight control system (21). The disconnection of the automatic pilot (26) and the switching-on of the flight control system (21) is delayed by a delay time which is at least approximately equal to a typical duration of a vertical gust of wind, and the switching-on of the flight control system (21) is not carried out unless the gust of wind persists when the delay time has elapsed.
