When a FADEC detects an abnormality in any of engine+compressor combinations, a FCC controls the amount of air for driving the fan to a level that is lower than that before the abnormality has been detected, until a state is assumed in which the normally operating engine+compressor combination can supply the air at a flow rate necessary for a fan to generate a propulsion force that has been attained before the abnormality has been detected. As a result, the normally operating engine+compressor combination can be prevented from the occurrence of a surge and a resultant overload state. Therefore, when some drive sources from a plurality of drive sources fail, normally operating drive sources can be prevented from being in an overload state.
