How it's REALLY done
Nah, you're all wrong.
Preflight the aircraft right where it is, walking around all the other aircraft in close proximity to do so.
Get in.
Turn on master and listen to the ATIS.
Fasten harness.
Attempt to adjust seat.
Release harness, adjust seat, refasten harness.
Turn off ATIS (been going all this time you see.)
Turn on magnetos.
Prime for a cold start.
Realise the engine is warm. Oh well, can't un-prime.
Staring at instrument panel, mumble "area clear".
Start engine.
Apply park brake.
Do some checks - magneto dead cut and so on.
Retard throttle so RPM gets back below 2000, where it's been since start.
Look up for the first time since pre-flight.
Shut down and move aircraft parked 1.7m in front.
Start again from "get in".
After all, 10,000 students can't be wrong can they?
