Method (10, 20) for training the piloting of a rotorcraft comprising at least two engines (3, 4) and at least one rotor contributing to helping keep said rotorcraft in the air, said method (10, 20) comprising at least the following steps: - piloting (11, 21) said rotorcraft according to a mode in which each of said at least two engines (3, 4) delivers a first engine power to rotate at least said at least one rotor, - activating (12, 22) a first command to start a training phase simulating an asymmetric flight in which a first engine of said at least two engines (3, 4) is configured to supply an engine power exclusively to said at least one rotor and a second engine of said at least two engines (3, 4) is configured to supply no engine power to said at least one rotor, - deactivating (15, 35) said first command to leave said training phase, characterised in that said training phase comprises a first flight phase comprising: ∘ a first regulation (13, 23) with a controller regulating said at least two engines (3, 4) each to deliver respectively a second engine power greater than said first engine power, ∘ a first display (14, 24) with a display unit of an item of carrier information of at least two simulated powers (PS1, PS2) capable of being delivered respectively by said at least two engines (3, 4), each of said at least two simulated powers (PS1, PS2) being distinct from said second engine power. said method (10, 20) comprising at least the following steps: - piloting (11, 21) said rotorcraft according to a mode in which each of said at least two engines (3, 4) delivers a first engine power to rotate at least said at least one rotor, - activating (12, 22) a first command to start a training phase simulating an asymmetric flight in which a first engine of said at least two engines (3, 4) is configured to supply an engine power exclusively to said at least one rotor and a second engine of said at least two engines (3, 4) is configured to supply no engine power to said at least one rotor, - deactivating (15, 35) said first command to leave said training phase, - piloting (11, 21) said rotorcraft according to a mode in which each of said at least two engines (3, 4) delivers a first engine power to rotate at least said at least one rotor, - activating (12, 22) a first command to start a training phase simulating an asymmetric flight in which a first engine of said at least two engines (3, 4) is configured to supply an engine power exclusively to said at least one rotor and a second engine of said at least two engines (3, 4) is configured to supply no engine power to said at least one rotor, - deactivating (15, 35) said first command to leave said training phase, characterised in that said training phase comprises a first flight phase comprising: ∘ a first regulation (13, 23) with a controller regulating said at least two engines (3, 4) each to deliver respectively a second engine power greater than said first engine power, ∘ a first display (14, 24) with a display unit of an item of carrier information of at least two simulated powers (PS1, PS2) capable of being delivered respectively by said at least two engines (3, 4), each of said at least two simulated powers (PS1, PS2) being distinct from said second engine power. ∘ a first regulation (13, 23) with a controller regulating said at least two engines (3, 4) each to deliver respectively a second engine power greater than said first engine power, ∘ a first display (14, 24) with a display unit of an item of carrier information of at least two simulated powers (PS1, PS2) capable of being delivered respectively by said at least two engines (3, 4), each of said at least two simulated powers (PS1, PS2) being distinct from said second engine power.
