Abstract: A method for controlling an aircraft (1) capable of hovering is described, comprising a first engine (10a); a second engine (10b); at least one rotor (3); and a transmission (8) interposed between the first and second engine (10a, 10b) and the rotor (3); the transmission (8) comprises a first and a second inlet (12a, 12b) connected respectively to a first outlet member (11a) of the first engine (10a) and to a second outlet member (11b) of the second engine (10b); the method comprises step i) of placing the aircraft (1) in a first configuration, in which the first and second engine (10a, 10b) make available a first and a second power value (PI, P2); or in a second configuration, in which the first engine (10a) makes available a third power value (P3) greater than the first power value (P1) to the first inlet (12a), and the second engine (10b) delivers a nil power value (P4) to the second inlet (12b); the method also comprises, characterised in that it comprises the steps of ii) detecting a series of parameters associated with the operating conditions of the aircraft (1); and iii) enabling the transition of the aircraft (1) from the first configuration to the second configuration, when the parameters assume respective first values.
