AGPU is generally used when the aircraft is parked at an aircraft stand. The electrical power requirement of an aircraft is not the same as domestic power supply.

What is the difference between an APU and a GPU?

What is the difference between an APU and a GPU in aviation? The APU (Auxiliary Power Unit) is the power unit contained on an aircraft which can provide electrical and pneumatic (air) power. The GPU (Ground Power Unit) is connected by the ground crew when the aircraft arrives at the gate an provides electrical power only.

Where is the auxiliary power unit located in an aircraft?
