109 e4 performance

Well basically we can say: the 109 as modelled in the sim is too slow (there is no speed variation in any plane so the in game 109 can be supposed to represent the average 109). It is even slower than the slowest ever performed flight test (on a special unit). It is well below the minimum spec. Conclusion: the 109 should be faster by a good deal. As there is currently no test data concluding that the 109E could reach 500 kph and the best ever obtained data in the tests that we dispose of is 494 kph the average should be in the middle of the 475-494 kph range for the average 109. This is about 485 kph. In case the devs will implelemt a variation they should apply a gaussian with average value 485 kph and 1 sigma = (485-475) / 3 = 3.3 kph.

Now I hope we can have a similar evaluation for all the other planes including the Spit 2a that seems to concord with some data given but we also should evaluate if it is based on average values or if it is based on test data that was more on the upper bandwidth than on the lower (or vice-versa). There is currently no clue whether the Spit 2a is representative of an average Spit2a or a lesser or better performing individual plane.

I still would say that the average, fresh from the factory, Bf109E should be able to reach 500km/h!

Of course the speed later on varies, depending on how the machine is handled.

If the machine is handled carefully, always warmed up enough and never exceeded the power ratings and also didn't have

accidents during the ground handling or damage through enemy action, then it might be even better then during the acceptance trials.

Otherwise, if one or more of the above conditions isn't met, the speed will be lower.

But then, if the speed and/or handling has detoriated to a given point, the aircraft will get a major overhaul or be sent to training units or wrecked.

If there is a variation from the factory-set standard speed it must work both ways, or it is biased, imo.

I agree, the problems is how to model this in the sim. Crumpp replied earlier, and I have no objections at all, because that sounds very reasonable, the max speed stated was reached on an Aa engine, 2500RPM 1.45ata, rads 1/4 open (or closed). That plus some variation modelled, e.g. some Emils would do slightly more and some slightly less - that would be great.
