1. 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 comprising at least the following steps:
flying the rotorcraft in an “All Engines Operating” mode (AEO) wherein each of the at least two engines delivers a first driving power (P1) to rotate at least the at least one rotor;
activating a first command to start a training phase (E) simulating asymmetric flight wherein a first engine of the at least two engines is configured to supply driving power on its own to the at least one rotor and a second engine of the at least two engines is configured to supply no driving power to the at least one rotor; and
deactivating the first command in order to exit the training phase (E),
wherein the training phase (E) comprises a first flight phase (V1) comprising:
a first control operation, with a controller, controlling the at least two engines to each respectively deliver a second driving power (P2) greater than the first driving power (P1), the first driving power (P1) corresponding to a minimum power for the rotorcraft to perform a cruising flight phase in the AEO mode; and
a first display operation for displaying, with a display, information carrying at least two simulated powers (PS1, PS2) that can be delivered respectively by the at least two engines, each of the at least two simulated powers (PS1, PS2) being different from the second driving power (P2), the second driving power (P2) corresponding to another minimum power in order for the rotorcraft to perform another cruising flight phase during the simulated asymmetric flight.
