PCD,
As I said, local conditions apply and in the circumstances you describe very practical ones too, but on a routine station (what's one of those today?) there is absolutely no reason why aircrew should not take their turn just like everybody else.
It's called officers' responsibilities and, after all, aircrew are officers first and aircrew second; like it or not! To those that don't like, may I humbly suggest that you chose the wrong career and would be better off with the 'bucket & spade' brigade where you can do your flying when rostered and do your garden and whatever else takes your fancy during the long lay offs between sorties!
As I said in my post above:
if you are officer or NCO aircrew you do your respective duty like everyone else and, during the down period, you wear the appropriate uniform which is not a flying suit.
That's the way we aircrew have always resolved it and I cannot think of a reason why circumstance might have changed.
I'm with incubus and stax! Get your uniform on and get the flag down (or up!)
