I’m an A320 line mechanic in the states, and we always hand the plane over to the pilots in a powered up state. Usually EXT PWR on, screens on, and ADIRUS aligned.

When i was working in maintenance for my company i normally gave the plane powered up, just powered but not setup. When i was working for an MRO normally cold and dark

Some US carriers prefer if you shut it down when it's going to be at the gate more than 90 minutes or so. If the next crew is waiting, we usually leave it all powered up with the APU on. If it's going to be around a while and ground conditioned air isn't available, we'll leave it running, too, especially in the summer. Sometimes you have to advise dispatch/maintenance/someone at the company if you're leaving the airplane unattended with the APU running. Terminating at the end of the day you have to check with local company operations. If the plane is staying on the gate overnight, they'll usually want you to shut it down all the way after everyone is off. Many times as soon as everyone is off, they'll push the plane back to a remote hard stand for overnight parking so they can use the gate for another arrival. In that case, they'll prefer the APU left on for the push crew. At my airline a lot of times the cabin crew doesn't stay at the same hotel as we do, so if we can leave it running, we just finish our checklists and then take off- before most of the passengers are even out. We'll wait if we're all staying together. When you show up in the morning at an outstation, I'd say the most common configuration is external power on, in "service" mode so the cabin lights are on but avionics aren't powered up. Some stations have non-pilots qualified to run the APU, and in those cases you might find it with the APU already running. This is also the case if you're not the first departure from that gate- the plane was on a hard stand and they towed it to the gate after someone else departed.

For sim pilots I think cold and dark is the way to go, if time permits. But when I’m in a hurry I will have it in a more prepared state.

I work at a mx base for a cargo airline in the US. We usually have the aircraft outside, powered up, APU on , IRU's aligned, packs on if needed. It's pretty much ready to go. They've just gotta do the walk around and input the flight plan. Certain flight mechanics do more for their planes than others. Some bake cookies at the start of their rotations.

Thank you! I would love to see more of these "background", company operation videos. :)

Die Frage wollte ich dir auch schon stellen. Danke.

With GFO, the received state will become more noticeable because it will depend on the previous captain. Great!

i would like to know how you do your tournaround procedures? Just set up the flight plan and do the brefing?

Can you put a video on transatlantic flights with ETOPS and the differences with ETOPS 60 flights

Do you fly the CEO and NEO, or just one or the other? If both, is there a difference in how they handle due to the larger engine and different wing on the NEO?

What about oposite situation when your crew is the last one of the day ? Are you responsible for turn off whole plane or not and for example secure cockpit or cabin after deboarding ?

I want to know at what point a pilot finds out the departing runway when ATIS states multiple departing runways. AS a noob, sometimes clearance delivery tells me and sometimes I get it from Ground. When do pilots key in the departure info in the FMC or do the perf calculations in the EFB? I'm always conflicted on this step.

Interesting that you tackled this subject, thank you. Over the last few months I've been watching the KZfaq channel of an American Airlines line mechanic based at KLAX. Most of the aircraft he works on are left powered up by their previous crews, or he starts them and leaves them running, unless they are going to the hangar. I won't mention his channel name out of respect to you, but happy to post a link if you say so.

Valeu!

I’m interested how the aircraft are secured when parked. Is there always staff around maintenance/ cleaning etc. do the doors lock from outside? Odd questions but wondering what happens with normal ground procedures

When is the sim update 15 coming out (time)?

You airline pilots are really spoilt. For us biz-jet jockeys it is cold and dark 99% of the time… but I guess our inflight catering makes up for it😎
