The Auxiliary Power Unit (APU) which generally serves as a generator of electricity for the cabin operation during flight, also plays a vital role in prompt start-up of the powerplant engines. Being located towards the aft of the aircraft, the exhaust when left unprotected can become easily obstructed while the APU is not operating.
