Hi Sabenaboy,
I understand your point, in my 2 previous airlines I had the same issue, there was nothing officially written about that subject so you would find people leaving the aircraft in transit preparation, others switching everything off and so on. In my current airline we leave the airplane in transit preparation whenever a relatively short transit is expected or we secure it with a higher transit, which is quite logical I think.
I think I have some documents from Airbus somewhere or at least I used to... I'm going to have a look around the hard drives
