@abbie.cheeseman: Just to clarify that many airports/airlines do prefer to use ground power units while on the ground regardless of APU status & depending on the airport/airline, they may or may not have air conditioning available at each gate. The APU isn't just some random vent hole at the back of your plane, it's a whole additional engine running before your pilots ever touch the real ones. When it breaks, ground crews have to hook up an air start cart to get one engine going, then feed that engine's bleed air over to start the second one. That's why a broken APU can mean a hot cabin and a longer wait at the gate. #aviation #APU #AviationTikTok #PlaneFacts #avgeek

fun fact: on US airways 1539 that went into the Hudson it was Sullenberger's quick thinking to turn the APU on that gave him flight controls as he glided down into the Hudson. That was not something that was on the checklist but he knew with both engines out he needed some sort of power for flight controls and instruments. This is reference quite clearly in the movie.

I once saw a plane with 3 condensation trails but it was a 2 engine plane so I think the apu was let on mid air

We used ground units at UPS and they were incredibly loud. I haven’t worked there in 25 years, so I don’t know if they still do

educational. Interesting. I did not know that. Always wondered what that hole was. I thought it was regular engine exhaust.
