What about anti-fire? 
Some flames could be put out by diving really fast/steep? Would be nice to have that modelled too.
In multiengine planes, maybe. In a single-engine plane you should get maybe 2 seconds then a 2-3 second fade to redout. Even if the fire isn't actually in the cockpit I think the pilot would very quickly have nothing on his mind other than getting out of the cockpit as soon as humanly possible. Also, I suspect most fires that were successfully put out were less serious than the catastrophic fuel tank failures that would create the 50-foot flame trail we see from burning planes in AH2.
Zekes seem to have even more ridiculous ability than any other plane to fight on for a few minutes as roman candles.
I'm not sure which I hate more, unrealistic (lack of) consequences of fire or the awful pilot wound mechanics. IMHO pilot wounds would be better modeled by having all control inputs reduced by a random factor and a random (from moment to moment) extra damping on them, and lowering the threshold for blackout to 2 or 3 Gs.
