Phoenix, Arizona – Airbus has designated the Honeywell 131-9A auxiliary power unit as standard equipment for its A320 family of aircraft for its fuel savings and reliability – it is no longer just a selectable option for airlines. Honeywell’s auxiliary power unit is a small gas turbine engine that provides electrical power for starting an aircraft’s main engines and runs air conditioning and other systems while the plane is on the ground. It also provides primary or backup electrical power for environmental, cockpit and hydraulic systems during flight.
“Reducing operating costs while offering customers the best air travel experience possible continues to be key for airlines,” said Brian Sill, president, Engines and Power Systems, Honeywell Aerospace. “Together, Honeywell and Airbus are offering A320 series customers an APU with best-in-class operational efficiency enabling more efficient, safe, and comfortable travel experience for airline passengers.”
Honeywell recently shipped its 5,000th 131-9A auxiliary power unit (APU). This puts the number of production APUs from the 131-9 family at more than 11,000 units, with more than 100 million total flight hours. The 131-9 series auxiliary power unit has been selected by airlines for the majority of narrow-body aircraft. Its proven reliability helps reduce delays and flight cancellations, allowing airlines to stay on schedule so that their customers can reach their destinations on time.
The 131-9 APU family features an electronic control box that integrates advanced, plain-English troubleshooting logic and health-monitoring capabilities for intuitive maintenance. The 131-9 APU’s operational efficiency, along with Honeywell’s global network of customer support managers and technical engineers operating in more than 30 countries, helps customers achieve on-time flight schedules.
Honeywell invented the first APU in 1948 and is still the largest producer of gas turbine engines across the globe. The company has produced more than 95,000 APUs, and has more than 36,000 in service today across more than 150 regional, executive, commercial, and military applications, including both fixed wing and rotary wing.
