The APU’s electric generator can be used during flight in case one or more of the aircraft’s main generators have a problem. The most important job for the APU is to provide redundancy. You’re hearing the APU doing its thing! Safety You’ll hear the familiar whine of a turbine engine, even though the main engines aren’t running. Next time you hop on an airliner (even a small regional jet), listen carefully as you board. This eliminates the need for using an external power source and a noisy air compressor cart to keep the cabin comfy while boarding. It also provides pneumatic pressure for air conditioning and, more importantly, starting the main engines. The auxiliary power unit is usually run on the ground during passenger boarding and deplaning. The APU turns an electric generator that powers the electrical system on the aircraft when the main engines are off. Most of the power produced is used to run an electric generator and provide pneumatic (air) pressure. Unlike the aircraft’s main engines, the APU outputs almost no thrust. The auxiliary power unit is an actual turbine engine, more appropriately called a turboshaft engine. Years ago, aircraft manufacturers and operators figured out that installing a small turbine engine in an aircraft’s tail is a great way to provide an extra level of safety, convenience, and comfort. Time to find out what’s hidden in the tail of your aircraft!Īirliners are loaded with redundant systems to help make them reliable. Hiding inside the tail of most every airliner is an extra engine called an Auxiliary Power Unit or APU. How many turbine engines are on an Airbus A320?įour engines? Wrong again. ![]()
