You'd just have to tie the O2 on/off to the alt when the game engine puts on the mask.

I'm not sure about this. What altitude & planes does the mask on/off kick in. Maybe works for jets, but I've never seen this feature occur in a prop plane, and I know beaufighter pilots used to use O2 when they flew over the Owen Stanley Ranges from Port Moresby to Buna in New Guinea.[/quote]
Fly to 3000m and in every plane the pilot puts on the mask.
