Abstract
A method of operating a rotorcraft with at least one main rotor and at least two engines, comprising: determining whether the rotorcraft is operated in an AEO mode wherein the at least two engines are powering the at least one main rotor, or in a SEO mode wherein only a first engine of the at least two engines is powering the at least one main rotor while a second engine of the at least two engines is inactive; if the rotorcraft is operated in the SEO mode, monitoring the first engine to enable detection of engine failures; and if during monitoring of the first engine an engine failure of the first engine is detected, entering into autorotation of the at least one main rotor upon detection of the engine failure by adjusting main rotor actuators of the at least one main rotor.
