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.
adaptive cruise controlAdaptive cruise control (ACC) maintains the distance to the vehicle in front of it. That distance, which is set by the driver as a number of car lengths, is measured by sending radar signals from the front of the vehicle. When the cruise control is turned on and the speed is set, the system automatically brakes and accelerates. Also called "active cruise control," "dynamic cruise control," "smart cruise control" and "intelligent cruise control."
Like regular cruise control, some ACC systems disengage at slower speeds. However, "stop and go ACC," also called "traffic jam assist," will come to a complete stop, which enables drivers to use the system in bumper-to-bumper traffic. See automotive safety systems.
