Pilot Fatigue Please.

[Glasses]

How about adding G limits to engines also Spit's engines had a very bad habit of quitting in neg gs due to oil being sucked out of ducts but I guess HTC won't model them any time soon......

Actually, there really does need to be some work on oil pressure...

planes with sump oil pumps can fly negative G's indefinately

Glasses it was a problem with the carburetor float.  During short periods of negative-g flight, it would cause an overly lean mixture, and during sustained flight in this condition it caused overly rich mixture.

The problem was partially solved by a modification which was standard from March 1941 and was invented by Miss Tilly Shilling.  This allowed short periods of negative-g flight.

By the end 1942 the Bendix-Stromberg injection carburetor became standard equipment on Spitfires and allowed sustained negative-g flight.

Great news funked!  Since I have often heard the RAFwobbles saying that the Spit IX is a 1942 aircraft, no doubt in the near future HTC will rectify this problem and ensure that both the Spit V and IX are unable to sustain inverted flight!

I don't know about fatigue. But I do wonder about a pilot's ability to look around so much while in high Gs. I was in the backseat of a T33 (F80 trainer) when the pilot suddenly did a break - put the wings vertical and pulled - without warning me. My head went to one side and there it basically stayed through the maneuver. I don't know how many Gs we pulled, but the curtains were coming down (not a tunnel, but a black out from the top down was how I recalled it). But I maintained some vision and knew what was up, I could have flown if I was flying I think. But I don't think I could have readily been looking back and forth and over my shoulders like you can in AH. I did wrestling bridge workouts in High School, I think my neck strength wasn't all that bad at the time? We could add this limitation to AH too but, then again, why?  Leave the blackouts as they are - already they are pretty annoying. By the way anyone know what Gs they pulled in T33/F80? Curious as I never did think to ask the guy. I'm guessing it was only about three G but not sure.

Jekyll we both know that the real limitation on sustained inverted flight is lubrication, and you wouldn't see any of these planes sustaining inverted flight if this factor were included in the sim.

I actually don't know for sure that the carb with Miss Shilling's invention couldn't keep provide fuel for sustained inverted flight.  I do know that there was some performance decrease in this condition, but the magnitude is not clear.  With the Bendix-Stromberg unit there was no change whatsoever in carb performance when inverted, and that's the distinction I was trying to make.
