i guess. Even still different airlines have different procedures for the same thing. One Airline might wait to turn of APU until 10,000 feet, another might have you turn it off as soon as you have two good engine starts. One way or another by the time you get into the real thing there are like 100 things you’ve had to unlearn from flying in simulators. That’s why i think it’s more familiarity since they won’t spend as much time training you on where the buttons and dials and switches are
