What is the role of a GPU in ground operations?

The GPU’s job on the ground is to deliver external electrical power to the aircraft while its engines and APU are off. This power lets the airplane run systems like avionics, lighting, flight instruments, and environmental controls without using the aircraft’s own power sources. It supports preflight checks, maintenance, and starting procedures by providing a ready, ground-based power supply. The GPU does not provide fuel, tow the aircraft, or itself act as the air conditioning unit (that service is handled by separate ground equipment that may be powered by the same electrical source).
