Abstract: A rotorcraft flight training method for a rotorcraft comprising at least two engines and at least one rotor providing lift helping to keep the rotorcraft in the air. The method comprises at least the following steps: flying the rotorcraft in a mode wherein each engine supplies driving power to the rotor; and activating a first command to start a training phase simulating asymmetric flight, the training phase comprising a first flight phase comprising a first control operation, with a controller, controlling the at least two engines and a first display operation for displaying, with a display, information carrying at least two simulated powers.

Abstract: A method for controlling an aircraft having at least two engines burning fuel and a transmission system connected to a rotary wing, each engine having a power shaft connected to the transmission system. An energy-saving phase comprises at least one energy-saving period comprising controlling, at an active rating, with a control system, one active engine from the at least two engines, and using the control system to stop or control, at an inactive rating, each inactive engine from the at least two engines that is not the active engine.
