Abstract
The present invention relates to a method for simulating a failure of a combustion engine (10) of a single-engine rotorcraft (1), the rotorcraft (1) comprising a controller (30) piloting the combustion engine (10). The method comprises: i) arming a training mode by operating an arming button (20) in communication with the controller (30), the training mode cannot be activated in the absence of said arming of the training mode, ii) subject to said arming, activation of the training mode by operating an activation button (25) which is in communication with the controller (30), the controller (30) consequently controlling a deceleration of the combustion engine (10) to reach the idle speed, iii) deactivation of the training mode by again operating the activation button (25), the controller (30) consequently controlling an acceleration of the combustion engine (10) to reach a flight speed, the training mode can only be reset during a new simulation phase.Abbreviated figure: figure 1.
