1. 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; and
displaying, on the display and at the command of the computer, a zero-thrust mark carrying a zero forward thrust applied by the at least one propeller; and
wherein the zero-thrust mark comprises a shape that matches a shape of the power section.
