Question

Can you use APU bleed air inflight?

Answer 1

Yes, APU bleed air can be used inflight for various functions on an aircraft.

Step-by-step explanation:

Yes, APU (Auxiliary Power Unit) bleed air can be used inflight.

An APU is a small engine located at the tail of an aircraft that provides electrical power, hydraulic pressure, and compressed air when the main engines are not running. Bleed air is compressed air taken from the APU or main engines and used for various purposes onboard the aircraft.

During flight, APU bleed air can be used for several functions such as pressurizing the cabin, operating air conditioning systems, and supplying air for the aircraft's pneumatic systems. Some aircraft even use bleed air to start the main engines.
