The aircraft (1) i.e. rotary wing aircraft, has a revolving aerofoil (2), two identical primary turboshaft engines (11, 12) and a secondary turboshaft engine (13) that is able to function according to a specific mode by providing a secondary power proportional to a main power according to a proportionality factor lower or equal to 0.5. A control system (20) drives the revolving aerofoil by allowing the primary engines to permanently function during a flight, and in complement allows the secondary engine to function during a predetermined specific phase. An independent claim is also included for a method for using an aircraft.
