Abstract:
1. A method of assisting the piloting of a hybrid aircraft having a rotary wing and at least one propulsive propeller, the method being characterized by the following steps: determining, by a processor, at least one thrust margin (ΔP) for said propeller between a current thrust (P determining, by the processor, a main minimum total ground slope (γ presenting on a display unit a main symbol for the minimum total ground slope that can be followed by the aircraft in descent, this main symbol being a function of at least the main minimum total ground slope (γ wherein in order to determine said thrust margin (ΔP), the following steps are performed: determining a current forward speed of the aircraft; determining a current power (W determining the current thrust (P determining said threshold thrust (P determining said thrust margin (ΔP), said thrust margin being equal to the difference between the current thrust (P
