Auxiliary Power Units
Higher Performance and Reliability
Honeywell is the largest producer of gas turbine auxiliary power units (APUs) found on many leading aircraft. With more than 95,000 APUs produced and more than 36,000 in service today, Honeywell has a large APU installed base and is poised for further growth. We’re powering more than 150 regional, executive, commercial and military applications, including both fixed wing and rotary wing.
Honeywell APUs continue to be the strong selection preference for high volume platforms like the Boeing B737 and Airbus A320. With our broad range of applications, we can support power requirements from 50 equivalent shaft horsepower (SHP) up to 1700 equivalent SHP.
Our innovative event- and usage-based aftermarket programs can be customized to your aircraft needs and business requirements to improve APU reliability, while decreasing overall maintenance expenses. Additionally, our APUs, when installed fleet wide, are proven to lower operation costs through unit commonality, reduced mechanic training and decreased inventory requirements.
