Engine failure training method for a single-engine rotorcraft

A method for simulating a failure of a combustion engine of a single-engine rotorcraft, the rotorcraft comprising a controller controlling the combustion engine, the combustion engine being able to operate on command from the controller in a nominal mode at at least one flight speed in order to provide a driving power to at least one rotor, the combustion engine being able to operate on command from the controller at an idling speed,

• wherein the method comprises a simulation phase comprising the following steps:
• arming a training mode by operating an arming button in communication with the controller, the controller controlling an operation of the combustion engine at the at least one flight speed, the training mode not being able to be activated in the absence of the arming of the training mode;
• subject to the arming of the training mode, activating the training mode by operating an activation button that is in communication with the controller and is different from the arming button, the controller consequently controlling a deceleration of the combustion engine to reach the idling speed;
• and
• deactivating the training mode by operating the activation button again, the controller consequently controlling an acceleration of the combustion engine to reach the at least one flight speed, the training mode being able to be reset only during a new simulation phase.
