The present disclosure provides methods and systems for operating a rotorcraft (100) comprising a plurality of engines (102, 104) configured to provide motive power to the rotorcraft (100) and at least one rotor (108) coupled to the plurality of engines (102, 104). Failure of an active engine (102) of the rotorcraft (100) is detected when the rotorcraft (100) is operated in an asymmetric operating regime (AOR), in which at least one first engine of the plurality of engines (102, 104) is the active engine (102) and is operated in an active mode to provide motive power to the rotorcraft (100) and at least one second engine of the plurality of engines (102, 104) is a standby engine (104) and is operated in a standby mode to provide substantially no motive power to the rotorcraft (100). At least one flight control input is adjusted to compensate for a reduction in rotational speed of the at least one rotor (108) resulting from the failure of the active engine (102). An increase in a power output of the standby engine (104) of the rotorcraft (100) is commanded.
