only a moron would use Dolby positioning in a game.
No, aircraft in WW2 were forbidden to go inverted for more than 10 seconds or so at a time (not so much with radial engines but with any V engine) as the engine would lose gas or if fuel injected lose oil pressure and burn up.
Not all WW2 planes would lose oil pressure if the plane flew inverted for more than a few seconds, some planes had oil systems to allow for inverted flight. In any case, since this isn't modeled in AH and you can fly inverted for however long you like, I don't see why there should be any issue to set auto-pilot to keep you inverted.ack-ack
Non of the WW2 era aircraft had "in-verted" fuel and oil systems! The spits and FW's for example had "float" type carburation system and they would stop running with-in about 3 or 4 seconds unless they were pulling at least 1 g while inverted! Since this is a computer generated game, aircraft in here do not know if they are upside down or not. Having said that, I remember flying a Spit 1 one day and lo and behold, rolling inverted did shut down the engine, so some of the aircraft in the game may be programed to shut down if left in inverted flight.
Not knowing all that about coding but I'm going to assume to allow only certain aircraft who had the ability of inverted flight would be a task. or should this be an all or nothing kinda thing.
