Guys,
Thanks for the feedback, I am familiar with the physics of the engine cut-off and am a student of the history of the development of the Spitfire, although not the Hurricane. I had an opportunity to talk about this with a Spit expert at Duxford on a trip back to the homeland (although at the time I was disappointed that the earliest Spit they had in the collection was a 5 - don't know if that has changed since) a few years ago who had in turn spoken with Jeffrey Quill about this and other problems. Incidentally, he noted that Quill had told him he regarded Aileron and Coolant problems to be the big bugbears in combat with the early mark Spits and not engine cut out.
The fact is that the engine did not cut out with mild negative G maneuvers any more than human beings "black out" with mild positive g maneuvers or "red out" with mild negative g maneuvers and AH2 obviously attempts to model the actual scale. The situation in the Carburetor of the Merlin is similar. The engine would only cut out when the neg g load (or unload if you will) reached a point that the float in the carburetor was all the way up and closed off the needle valve flow to the engine. This occurred when the pilot suddenly nosed the aircraft down into a really steep dive. At present the engine cuts out when you nose down slightly for landing (producing a brief low negative g), a situation that would have caused a LOT of crashes in reality. I never bothered to ask what the negative G point was when the engine cut off (-2, -3, -4 etc.) but it certainly wasn't -1 G and under as it is in the game.
If you want to enter into a discussion of this and have solid information that the slightest amount of negative Gs (-0.1 to -1) produced the cut off, I'll be glad to stand or rather sit corrected, but as this would have made the aircraft totally unsuitable for use in combat I rather doubt it at present.
Thanks,
SEAGOON
