Abstract: A method for training a pilot to cope with a fault affecting one powertrain of a hybrid propulsion system for an aircraft. The aircraft includes, connected in parallel to a transmission unit, n powertrains (where n?2), including a first and a second powertrain that are heterogeneous in nature. It involves, during a flight of the aircraft, simulating a fault affecting the first powertrain while, at the same time as performing the simulation, checking the status of the n powertrains of the propulsion system. If a fault affecting one of the n powertrains is detected, the simulation is halted and the instantaneous power delivered by at least one of either the first or the second powertrain is increased so that the sum of the instantaneous powers delivered by the n powertrains is ? a minimum total instantaneous power required for the aircraft to continue its flight.
