Original Note:
An APU (auxiliary power unit) works in a similar way to an aircraft’s engine and has three roles: to supply conditioned air to the cabin, as a source of electrical power for the aircraft and lastly as a means of engine starting. https://www.aviationmatters.co/what-is-aircraft-auxiliary-power-unit-apu/
