cruise control[′krüz kən′trōl]
The act or practice of operating an aircraft so as to achieve the most efficient performance on a given flight under available conditions; it may be instituted to obtain maximum economy, endurance, speed, or range, or maximum efficiency at a predetermined airspeed or power setting.
An engine operating procedure that allows the best efficiency for power and fuel consumption during cruising. In the case of reciprocating engines, as fuel is consumed and the aircraft becomes lighter, cruise control is exercised by maintaining altitude and either reducing power while maintaining constant speed or by letting the speed increase at a constant power setting. In the case of gas turbine engines, the normal procedures employed are maintaining constant altitude and cruise RPM, by the stepped-up climb method and the cruise-climb method.
