Abstract
A method and a device for estimating the instantaneous mass of a rotary wing aircraft, the aircraft having a power plant driving at least one main rotor and an anti-torque rotor in rotation, and also having a plurality of sensors. The method uses functional characteristics and flight characteristics of the aircraft, atmospheric characteristics, and performance curves for the aircraft to determine the measured instantaneous mass Mof the aircraft. Furthermore, the method makes it possible to consolidate the measured instantaneous mass Mof the aircraft by comparing it in arithmetical or statistical manner during a flight of the aircraft with a calculated instantaneous mass Mdetermined from the variation in the quantity of fuel present in the aircraft.
