What Is Covered Under Aircraft Auxiliary Power Unit Market?

An aircraft auxiliary power unit refers to a device on aircraft that allows an aircraft to function independently without needing ground support tools like a ground power unit, an external air-conditioning unit, or a high-pressure air start cart. APU supplies critical electric power for aviation systems and is typically utilized to start one of the main engines on an airliner. It is also used to bleed air to start the main engines. The main products of aircraft auxiliary power unit are battery power and electric ground power. The aircraft auxiliary power unit is used in various types of aircraft, such as fixed-wing, wide-body, narrow-body, rotary-wing, unmanned aerial vehicle, and others. A fixed-wing aircraft refers to an aircraft that flies using wings and the shape of the wings. These are used by several end users, such as military aircraft, commercial aircraft, and general aviation.

What Is Driver Of The Aircraft Auxiliary Power Unit Market?

The increasing number of aircraft deliveries is expected to propel the growth of the aircraft auxiliary power unit market going forward. Aircraft deliveries refer to the process of manufacturing, assembly, and delivery of aircraft to customers, which can include airlines, private owners, or military organizations. The APU provides energy to the aircraft's electrical and pneumatic systems, allowing the aircraft to operate independently on the ground or during maintenance work. This reduces the reliance on external power sources and provides greater flexibility for the airline. For instance, in January 2024, according to the Airbus SE, a France-based aerospace and defense company, in 2023, Airbus delivered 735 commercial aircraft, marking an 11% increase compared to 2022. The company recorded 2,319 gross orders (2,094 net), which included 1,835 A320 Family aircraft and 300 A350 Family aircraft. Therefore, the increasing number of aircraft deliveries is driving the aircraft auxiliary power unit industry.
