Can the APU pressurize the cabin?
Excuse me, but I'm a bit confused about the capabilities of the APU. Could you clarify if the APU, or Auxiliary Power Unit, is actually capable of pressurizing the cabin? I've heard some conflicting information on this, and I'm trying to get a definitive answer. My understanding is that the APU is primarily used to provide electrical power and air conditioning to the aircraft when the main engines are not running. So, does the APU have the ability to also regulate and maintain cabin pressure, or is this a separate system altogether? I appreciate your help in clarifying this matter.
