Hi Karnak,
>So you're saying that the AH Fw190A-5's deck speed is more accurate than this chart?
Yes, the value posted in this thread is very close to the one achieved in the US test.
>You're also saying that this chart is not based on flight tests, but rather on paper calculations?
Yes - at least that's what I suspect, though I can't prove it.
Regards,
Henning (HoHun)
