Hi Ace,
I really appreciate your detailed reply. I was just wondering if you have come across this book and if it might be useful for general purpose reading on WW II aviation: Luftwaffe test pilot: Flying captured Allied aircraft of World War 2, by Hans-Werner Lerche? I used to own a German copy of it a long time ago, but I don't have it anymore.
With all this, I have another comprehension question. How are aircraft performance data gathered? What I mean is, are the data that show up in the graphs from only a single flight (that would be unlikely, wouldn't it?), or are they an average, calculated from several performances under similar conditions?

Ace: "Well I already covered the gathered aspect and how it is unlikely that they would knowing fake the numbers
But I am interested in how you think the numbers would change due to publishing or dissemination?
Do you have an example?"
RB: At the moment I don't. I will let you know when I find one. I was thinking of discrepancies between prototypes and production aircraft. On top of that, at least in Germany, there was plenty of in-fighting between different aircraft manufacturers and various branches of government and the military. For example, in regard to the He-219, or the Ta-154 Moskito. I think that it is possible that in the course of these internal conflicts data may have been tampered with for political reasons. However, at this point, I cannot prove it, so it's a only theory at the moment. Nonetheless, based on descriptions of the political climate of a "culture of fear," that I heard from my relatives, friends and acquaintances who lived through the war in Germany, I think such things are entirely possible.
Ace: "It is know that the AI does not have over heat issues, thus they can push their planes harder than a real person could, so maybe your seeing that."
RB: All the time!
:wink:
Ace wrote: "In that I think the state of the other plane and pilot is important
Very important
And that is my point
Not knowing anything about something that important is what makes most if not all combat reports useless wrt determining the performance of a plane."
RB: I see. Are you saying that because the pilots were not necessarily in a neutral, or objective state of mind, the technical value of their observations is difficult, if not impossible to ascertain?
By the way, do you have any information on how performance data recorded in the 1940s would compare to performance data of restored aircraft of the same type flying today? Or is that not a valid comparison?
Thanks again.
Regards,
RB
