Preconditioned Air(PCA) Units for Aircrafts
What is a PCA Unit?
Preconditioned Air Unit(PCA) is a specialized air conditioning device on the ground designed to provide fresh air that has been filtered, pressurized, dehunidified, and cooled(or heated) for aircraft cabins parked on the ground.
Key points about PCA units:
- Provide conditioned air to an aircraft on the ground, maintaining comfortable temperatures for passengers without relying on the aircraft’s APU.
- Reduce fuel consumption, decrease noise pollution, and lower emissions by utilizing the airport’s power grid instead of the APU.
PCA units are powered by electricity and provide significant advantages over APUs, including lower operating costs, enhanced user comfort, and greater environmental sustainability.
According to Honeywell’s fuel consumption cost data in the US, the hourly operating cost of an APU is approximately $75.24, whereas a PCA unit costs around $11.37 per hour—84.9% less than an APU.
