Abstract:
1. A method for automatically detecting, on board an aircraft (A), during a flight, a lateral dissymmetry of said aircraft (A), comprising automatically: a) determining, by a processor, the current values (P, R) of a first couple of flight parameters of the aircraft, which represent the roll rate and the yaw rate of the aircraft (A) and the current values (DP, DR) of a second couple of auxiliary parameters illustrating the deflections of control surfaces ( b) carrying out, by a processor, a dynamic monitoring function comprising:  said successive steps a) and b) being implemented repeatedly; c) when an enabling signal is transmitted, at the end of a predetermined auxiliary period after such transmission, carrying out a static confirmation function for checking whether the equilibrium current values (DP, DR) of said second couple are in at least a predetermined auxiliary set (E d) when a detection signal is transmitted, using said dissymmetry information on board the aircraft (A).
