An Auxiliary Power Unit (APU) is any gas turbine-powered unit delivering rotating shaft power or compressed air, or both, that is not intended for direct propulsion of an aircraft. APU's often drive aircraft generators, air-conditioning packs and in some cases can be used as an additional source of energy to start the primary propulsive engines
