Honeywell makes aviation history with new production milestones Honeywell has reached two major milestones in the production of auxiliary power units (APUs) for aircraft — rolling out its 100,000th overall and the 15,000th of its most popular variant flying today, the 131-9 model.
APUs provide power to tens of thousands of aircraft in the skies today. Numerous commercial and military platforms have relied on Honeywell APUs to start their main engines and provide additional power to other important systems.
Honeywell's first APU took to the skies in 1950, with more than 36,000 in service today across more than 150 regional, executive, commercial and military applications, including both fixed-wing and rotary-wing aircraft.
