Method and system for determining the longitudinal position of the gravity center of an aircraft provided with an adjustable stabilizer. At a point of flight for which the aircraft is in equilibrium with its elevator in aerodynamic prolongation of the adjustable stabilizer and when the gravity center is at the vicinity of the focus of the aircraft, the gravity center position is calculated from: the position (XF) of the focus (F) of the aircraft, the measurement of the deflection (iH) of the adjustable stabilizer, a first function K(M, N1) of the engine ...
