Performance of the Fw 190A on the Deck?

What I and Graham have pointed out is that for these kind of aircraft the speed reduction is small at high speed near sea level. And we both do that correctly by using the polar and iteration method which accounts needed higher Cl/Aoa.

Your approach assumes constant Cl/AoA which is not a correct approach for this particular case because with given available power the plane can't maintain constant AoA at higher weight.

It's not "my technique" but very basic use of the polar; Graham does the calculation with the very same principle and anyone with sound basic knowledge would use this technique. And I teached you to use it in Ubiforums some time ago:

You might remember that then you claimed this technique as "misuse of formulas" so I afraid that the sensible discussion is impossible in this case as well.
