Honeywell said it won a $16 billion contract to provide major mechanical systems for Airbus’s new long-range, wide-body A350 aircraft. Honeywell said it is the largest systems and equipment package Airbus has awarded to date on this program. As part of the 20-to-25 year agreement, Honeywell will design and build an auxiliary power unit (APU) and provide the APU Installation Kit and APU Starter-Generator, which will supply pneumatic and electric power for the aircraft while on the ground or in flight. The company will also provide integrated systems to manage all of the air used on the aircraft for environmental control, including cabin heating and cooling and cabin pressurization.
