1. A method for generating at least one set point from among a primary set point and a secondary set point, the primary set point being chosen from among a flight control set point for a flight control system of an aircraft and an engine control set point for an engine control unit of the aircraft, the secondary set point being a guidance set point for a guidance system of the aircraft, the aircraft comprising the flight control system, the engine control unit, at least one guidance system, at least one primary control member, and an electronic device for generating the set point(s), the primary control member being configured to be manipulated by a user to pilot the aircraft, the primary control member being selected from the group including: a control stick, a mini control stick, a rudder bar and a throttle, the method being implemented by the generating device and comprising: acquiring a mechanical property relative to at least one corresponding primary control member; computing at least one set point from among one or more primary set points and one or more secondary set points; generating at least one of the computed set point(s), for the corresponding system from among the flight control system, the engine control unit and the guidance system; and switching, based on the mechanical property acquired for the corresponding primary control member, between a first mode in which one or more primary set points are generated and a second mode in which one or more secondary set points are generated.
