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 ...
A system for determining the longitudianl position XG of the centre of gravity G of an aircraft in flight, said aircraft being provided with an adjustable horizontal stabilizer which is deflectable and to which is articulated an elevator, said aircraft having a determined focus F with a longitudinal position XF, speed of engine, Mach number and coefficient of lift, said system comprising: means for transferring fuel from one tank of the aircraft to another; angular position sensing means associated with said adjustable horizontal stabilizer for measuring...
