| 1. A method of assisting the piloting of an aircraft, comprising:
determining via a processor a variation (DVZ) in the vertical speed of the aircraft as a function of a variation (DVH) in
the horizontal speed of the aircraft and as a function of data representative of the power absorbed (W) by the main rotor
of the aircraft used in providing the aircraft with lift and forward drive;
calculating a ratio between the variation (DVZ) in vertical speed and the horizontal speed (VH) of the aircraft; and
presenting a piloting assistance symbol (21) on a display (12), with the position (α) of the symbol being a function of said ratio.
