Abstract

An aircraft towing tractor has its acceleration limited to a predetermined limiting acceleration to reduce stresses upon the aircraft undercarriage by a computer-controlled regulator interposed between the gas pedal and the internal combustion engine. The regulator can also provide control of the speed increase of the engine below a predetermined limiting value thereof prior to control of the limiting acceleration.
