Interesting that you keep talking about the 6 1/4 boost and not the 12 boost.

In fact we all do, except for you. The discussion is about trying to explain to you the fact that the 109E has a better sustained turn than the Spitfire using 6 1/4 boost at and above 400 km/h near SL.

less than a 12 boost Spitfire

... and how much is that David?

Spit every time.

And why is that, David? How can a Spitfire sustain a turn without any excess thrust to start with? Does it have anti gravity drives perhaps? Can it just defy the rules of physics?

I am sorry David, but I believe that you did not fully grasp some of the basic elements of the this discussion, such as the difference between sustained and unsustained turns, the effects of parasitic and induced drag depending on airspeed and the importance of thurst and excess thrust. So let me put it down for you in the most simply terms:

Unfurtunately, the Spitfire cannot sustain a turn at 400 mph at all. Depending on altitude, it has either ZERO or NEGATIVE "excess" thrust already at 1 g.

We have been over this already anway, see http://forum.1cpublishing.eu/showpos...&postcount=194



In short, the 262 (blue line) starts to run circles around the Spitfire IX (red line) above 460 km/h. At 640 kph, the Spitfire is outright hapless...

I am still trying to work out how the German test authorities got it so wrong.

Nope, they got it exactly right. They say:

In summary, it can be said that all three enemy planes types are inferior to the German planes regarding the flying qualities. Especially the Spitfire has bad rudder and elevator stability on the target approach. In addition the wing-mounted weapons have the known shooting-technique disadvantages.

It seems to me that the Germans regarded the flying qualities of the Spitfire overall inferior to their fighters.
