Classification: CPC B  G | IPC B

Claim 21:
22. A method for assisting the piloting of a propeller rotorcraft, the propeller rotorcraft having a power plant connected by a mechanical system to a rotary wing and to at least one propeller,
wherein the method comprises the following steps:
displaying, at the command of a computer and on a display, a minimum power mark and a maximum power mark on a first scale, the first scale representing a power consumed by the at least one propeller, the minimum power mark representing a minimum power that can be consumed by the at least one propeller, the maximum power mark representing a maximum power that can be consumed by the at least one propeller;
displaying, at the command of the computer and on the display, a second scale graduated in forward speed of the propeller rotorcraft;
displaying, at the command of the computer and on the display, an index comprising a power section representing a current power consumed by the at least one propeller, the index comprising a speed section indicating a current forward speed on the second scale, the index and the first scale being able to move relative to each other, the index and the second scale being able to move relative to each other;
wherein the method further comprises using a position sensor to measure a current position of an interface controlling a mean pitch of each blade of the at least one propeller, the interface being able to move between a first position and a second position shown by ends of the first scale, the first scale being graduated in positions of the interface, the method comprising the following steps:
using the computer to determine the maximum power, the minimum power and the current power;
displaying, on the display controlled by the computer, the index as a function of the current position;
displaying, on the display controlled by the computer, the maximum power mark relative to the index as a function of a first difference between the current power and the maximum power; and
displaying, on the display controlled by the computer, the minimum power mark relative to the index as a function of a second difference between the current power and the minimum power.
