Also, never in the 5 years flying Airbus I saw a cockpit crew testing the APU fire pb while it was running. Thus my question. The FCOM Regarding the cockpit preparation assumes the APU was not running. It’s not very clear IMHO that we are supposed to test the APU if already running. In any case, I trust our maintenance to have done it. It’s part of their daily check.
We have no last flight of the day as we operate 24 hours per day. I get to a cold dark cockpit at least a couple of times a month, and if there aircraft has been switched on by MX there's always things still off we switch on like crew OX. Our OM specifically states to test regardless if it's on.
I guess there's a lot of different ways to get the same thing done......
