Method of controlling aerodynamic means of an aircraft, an associated control system, and an aircraft provided with such a control system

A control method for controlling aerodynamic means of an aircraft having mechanically decoupled flight control members enabling the aircraft to be piloted by at least two pilots, the aircraft having a first control member on a left side of a cockpit of the aircraft for being operated by a first pilot who is in charge of the first control member and a second control member on a right side of the cockpit of the aircraft for being operated by a second pilot who is in charge of the second control member and each control member enabling control signals to be generated for causing the aerodynamic means to move relative to an incident air stream, the control method using piloting logic referred to as “operational” logic, the operational logic including a dual operating mode, a left single-pilot operating mode, and a right single-pilot operating mode, the aircraft further including a single switch movable between three stable positions including a first position corresponding to the dual operating mode, a second position corresponding to the right single-pilot operating mode, and a third position corresponding to the left single-pilot operating mode, each of the positions of the single switch being reversibly-reachable for manual selection by at least one of the pilots of the dual operating mode in the first position of the single switch, the left single-pilot operating mode in the second position of the single switch, or the right single-pilot operating mode in the third position of the single switch;

• wherein in the dual operating mode,
• only one of the control members, referred to as the “activated” member, has exclusive control over a full travel amplitude of the aerodynamic means, the other of the control members, referred to as the “deactivated” member, then being temporarily inoperative on the aerodynamic means;
• it is possible to manually activate the deactivated member, thereby automatically deactivating the activated member responsive to the deactivated member being activated, the deactivated member being activated becoming the activated member having exclusive control over the full travel amplitude of the aerodynamic means;
• and
• the manual activation of the deactivated member is performed by other means distinct from the single switch;
• wherein in the left single-pilot operating mode,
• only the first control member, referred to as the “activated” member, has exclusive control over the full travel amplitude of the aerodynamic means, the second control member, referred to as the “deactivated” member, then being inoperative on the aerodynamic means;
• and
• the first control member always remains activated and the second control member always remains deactivated;
• wherein in the right single-pilot operating mode,
• only the second control member, referred to as the “activated” member, has exclusive control over the full travel amplitude of the aerodynamic means, the first control member, referred to as the “deactivated” member, then being inoperative on the aerodynamic means;
• and
• the second control member always remains activated and the first control member always remains deactivated.
