Gibbage I qualified my statement ref LOX i.e. in "breathing systems". I presume in your comment this was what you were referring too in terms of having tanks being included in the damage model ?. For the record only 3 spitfires were modified for LOX injection direct into the carburettor intake. A MKII P8079 in 1940, 2 MKVII's EN467 and EN470 in 1944. The system never became operational nor do I think it did with any other type.
CAGING INSTRUMENTS
Thats a good point vanderstock. That would add a nice touch of realism. Though in general the Gyro instruments could be caged by the pilot prior to combat. Once out of combat they can be uncaged and fast aligned with the real horizon in the case of artificial horizon. Once this is done then they are usable once more. This would make sudden entry into cloud in the middle of a fight a challanging affair ... how good are you on limited panel
Bussard_1 .. good idea having an AI marshaller. As is getting Roll rates right.
