Method for assisting the piloting of a rotary wing aircraft in a fuel-economy mode

Abstract

A method for assisting the piloting of a rotary-wing aircraft, the aircraft including at least two engines, a first engine being able to be put in standby to ensure the operation of a second engine in fuel economy mode, the so-called ECO mode, a method in which, to achieve a determined number of flight hours between two overhauls by limiting the wear of the second engine in ECO mode, an engine control temperature associated with the second engine is computed in a flight computer as a function of a maximum power predefined in ECO mode of the second engine, the engine control temperature being representative of a current state of damage of the second engine and displayed on a flight screen for the attention of a pilot of the aircraft, so as to allow him to remain below the engine control temperature.
