According to the game manual,

the 109 has a top ceiling of + - 10,000m

Is this a bug or is there something I am doing wrong here?

Of course late 109's were able to reach service ceilings beyond 10,000 meter. When we speak about the iL2COD "109"we have speak about the BF109-E.

I do not know any document from Daimler Benz, Messerschmitt or Rechlin, which reports a BF109-E ceiling above 7500 meter.

Long story short, a the ceiling of 10,000 meter with a real DB601A-1 in a real BF109-E was not possible.

The Bf109E could only reach 24,600ft?

Of course it did. I direct you to the specifications of the Bf 109E, 1939

http://www.kurfurst.org/Performance_...chreibung.html

"Dienstgipfelhöhe.

Die Dienstgipfelhöhe beträgt bei voller Ausrüstung 11 000 m."

Service ceiling.

The service ceiling is 11 000 meters with a fully equipped aircraft.

Note that this is service ceiling. Service ceiling is an altitude at which the aircraft could still climb at defined rate of climb, from memory it was defined by the Germans at 0,5 m/sec in other docs. So the absolute ceiling (climb = 0 m/sec) is a bit higher.

Some time ago I made some tests in IL2 COD, and became to the conclussion that the info that the developers used was for the engine DB601A-1 bei altem lader (VDH/FTH 4 km) (old compressor).

Those tests were made with patch version 145.50.

I never tested again in the actual patch but I reckon it remains the same.

The same engine with the new compressor (Bei neuem lader) with 13 blades,
DB601A-1 bei neuem lader** (VDH/FTH 4,5 km) gave better performance in RL.

See the graphs below, red curve is my test, fits pretty accurately with the specifications for the engine with the older compressor.

Nice advertise for your Website ...

I am looking for BF109-E documents from Daimler Benz, Messerschmitt or Rechlin, not for wikipedia-like web sites. I didn't find any document on your site dealing with a whatever 11.000 m ceiling concerning a E-version.

[Kurfürst]

In that case you should firmly stick to your idea that the 109E had a sub-10km ceiling, dear 'Varratu'.

[Varrattu]

Thank you for your honest statement Kurfürst.

So I like to repeat:

A ceiling of 10,000 meter with a real DB601A-1 in a real BF109-E was not possible.

On the other hand to say its a minority view is an extreme case of understatement.

Who painted this nice picture?

[IvanK]

Its source is AVIA 6/9352 the original is in the UK National archives. The document is a RAE document reporting flight test of a BF109E3 and BF110C.

Here is an image of the original document taken from the file itself:
