Can a plane fly with no APU?
Inquiring minds may wonder: Could an aircraft successfully embark on its journey despite lacking an Auxiliary Power Unit (APU)? The APU, typically a small gas turbine engine, provides electrical and pneumatic power to the aircraft while it's on the ground and its main engines are not running. It's crucial for starting the main engines, powering avionics, and maintaining cabin comfort. But, could a plane potentially circumvent this dependency? Are there contingency measures that allow for take-off and flight without an APU? The question begs for an exploration of the technical intricacies and operational contingencies that may enable such a feat.
