Aircraft Auxiliary Power Unit Market Size

Global Aircraft Auxiliary Power Unit Market Overview

According to the Aircraft Auxiliary Power Unit Market research report, the global market is estimated to USD 4.3 billion witness a CAGR of more than 3.20% in the forecast period 2024-2030. 

Increasing demand for Aircraft Auxiliary Power Unit can be seen in various end-user industries such as civil aircraft, military aircraft, etc. This is expected to drive the marketing of the Aircraft Auxiliary Power Unit in the Global Market Forecast. These Auxiliary Power Units, otherwise called APUs, are generally gas turbine engines used during aircraft ground operations to access electricity, compressed air, and shaft power. This shaft power is essential to start the main engine, air conditioning, and other electric power and systems associated with aircraft. These APUs are essential for the aircraft industry to offer backup electric power during in-flight operation if rare circumstances such may occur, such as in case both engines fail to perform.

As per the Aircraft Auxiliary Power Unit Market Outlook, the aircraft APUs help with supplying power to all main aircraft engines. Aircraft mostly use turbine engines that need to be propelled at a high-speed rotation, so the process can offer necessary air compression to maintain the engine's desired efficiency. These APUs are usually able to produce 115V alternating current at 400Hz. As an auxiliary power unit gives the advantage of using it as a supporting engine, its demand in the market is expected to boost in the coming years. Since the aircraft manufacturing industry is expanding due to upcoming technological advancements, it is easily triggering the growth of the global Market. Many developmental innovations in the aircraft electric architecture have influenced development in all-electric APUs that have gained more pace over the past years. Their implementation benefits can provide further growth opportunities for the aircraft APU market in the upcoming years.

Covid-19 Impact Analysis

The COVID-19 pandemic has severely affected the aviation industry in the past year, as almost all countries have issued bans on their national and international travel activities. Moreover, there were other lockdown restrictions imposed all across the globe, and its impact is not just limited to the aviation industry but extended to every segment of the aviation and aerospace industry, which also includes the Aircraft Auxiliary Power Unit Market size. Due to various travel restrictions and economic slowdown because of the pandemic, the airline industry has fallen in demand, so many airline entities have been practicing reducing air travel costs and expenses, which also involves cutting down on MRO spending. As the aircraft are aged, more maintenance has been required that can enhance their expenses. So the airline entities are replacing their older aircraft with new ones, which has started positively affecting the Market globally. And now that the severity of the pandemic situation is gradually getting better, the Market Outlook is expecting to see more growth in the forecast years.

Market Dynamics
