109 e4 performance

[Crumpp]

That is the Yugoslavian test

It is German test but is reprinted in a Yugoslavian report. Of course it is, the Yugoslavian's purchased Bf-109E's...

The Yugoslavian report is used to date the German one.

Reproduction of pages 48 - 53 from Baubeschreibung für das Flugzeugmuster Messerschmitt Me 109 mit DB 601, from circa 1939. The date cannot be positively identified, however, the Yugoslavian translation of the manual, probably shipped along with the Yugoslavian export Bf 109Es, and which is otherwise identical to the German, is dated 1940.

There is no mention of the aircraft actualy achieving 500km/h, at least I can not see it anywhere.

Sure there is:

Die Flugdauer bei Vollgasflug beträgt 1,1 h in 6000 m.
Bei entsprechender Drosselung erhöht sich die Flugzeit bis
auf zwei Stunden.

They flew at full power for 1.1hours, to altitudes of 6000m, and the total flight lasted 2 hours.
