Abstract
A method of assisting the piloting of an aircraft, such as a helicopter, includes determining a limiting power margin of a power plant of the aircraft relative to a power limit at an operating rating of an engine of the power plant. The limiting power margin is transformed into a collective pitch margin for the operating rating. The collective pitch margin represents the margin between a current collective pitch of blades of a main rotor of the aircraft and a collective pitch limit of the blades of the main rotor. The collective pitch limit is determined and then displayed on a display of the aircraft for a pilot to view.
