IAS and TAS almost the same at sea level.

@Kurfurst - I will test the Emils top level speed tonight and will post results here.....I doubt its only 470 kmh

I've not really studied the 109 very much but I am confused. This isn't meant to be a provocative post, I'm just wondering what it is we are supposed to have in CoD.

Where in that Spitfire Performance chart does it say the 109 does 560kph at S.L. (350 mph) and which 109 variant?
I see:-
BF109E Hochste Waagerechte geschwindingkeit, Flugzeughandbuchn 16 December 1939: 287mph/459kph
Bf109-E1 Nr 1774, 1.3ata, Bayerische Flugzeugwerk, 26.4.38: 302mph/483kph
Bf109-E3 Nr 1792, 1.3kg/cm2, Messprotocoll vom 16.2.39, Mtt A.G. Augsburg:290mph/464kph

500kph according to the Kurfurst site text is the E-3 (Spitfire performance gives the E-3 as 290mph/464kph). The Blatt 6 for E-3 actually shows a corrected 487kph after the test result of 485 using an underperforming engine. The Swiss result for the E-3 is around 470kph and the Kurfurst site uses the assumption that the appropriate supercharger gear was not used to suggest that the result was lower than it should be. The French result shows approximately 487 at ~250m.

My only point is that the specific E model/Engine/Propeller etc should be clear along with the most important question - just which 109E-1 and 109E-3 configurations is CoD supposed to be giving us?
