Abstract
A flight control method and system for a rotary wing aircraft. When the longitudinal speed Uof the aircraft is greater than a first threshold speed V, a first mode of operation of the method enables flight to be performed while maintaining track relative to the ground, the flight setpoints of an autopilot being a ground course angle TK, a forward speed Va, a flight path angle P, and a heading Ψ. When the longitudinal speed Uis less than a second threshold speed V, a second mode of operation enables flight to be performed while maintaining heading, the flight setpoints being the longitudinal speed U, a lateral speed V, a vertical speed W, and the heading Ψ.
