Conditioned or for starting.
Need it or not that was the working theory.
Question asked here was why would you keep one running and which one.
So that proves to be incorrect.
Was still a plausible explanation with the information available.
Then came the whole discussion if you needed air or not and everyone headed for the weeds.
There are more reasons why you’d shut down the left engine on different types of airplanes:
- Fuel panel left wing
- Jetway and access door
- Air hookup
Its a useless discussion now though.
It was a useless discussion at the start. WTF are you on about? The position of the fuel panel, jetway or air hookup points have nothing to do with which engine you leave running.
We don't do 'hot refuelling'.
We don't attempt to hook up the air with engines running. Ever!
Only under extreme circumstances (EG war zone) would you leave an engine running while offloading/embarking passengers.
For the record. Again. With a duff APU, one or more engines will be left running until the electrical power is connected. It/they are then shut down. The beacon goes off and then and only then are chocks, other ground equipment, servicing vehicles and the airbridge/steps allowed to approach the aircraft.
