LW aircraft speed specifications

[Crumpp]

If the russian's calibrate their instruments based on the common expression for compressibility used at the time, they will always measure results which are slower than the German's.

Now, I don't know if that is the answer in this specific case. No details are passed along in the anecdote.

Robteks first post in this thread was spot on.

Robtek says:

This is so unspecified that it is absolutely worthless besides the anecdotical value.

What german fighters in which version and what equipment? No Information.

Were they trying to reach the 190 A8 speeds with a F8 or so?

And then hearsay from a german specialist, who might say anything to please his new masters.

Worthless for any real value deductions, i'd say.

I just took the opportunity to demonstrate the following to the community.

It is a fact, the expression for compressibility effects was NOT the same. The implication of that is you cannot take performance data from different countries during WWII at face value.

The other damning fact is that all instruments, manifold pressure, rpm, airspeed indicators, altimeter, etc...require both periodic maintenance and calibration.

You claim to be a pilot but do not seem to understand these basic facts.

Instead you leap on the anecdotal bandwagon because it is something you think will advance your game shape agenda.

It is no different than the ridiculous "testing" of performance without first understanding the atmospheric conditions.

Both incident's are example of behavior that folks who understand aircraft performance would not undertake!! Like I did, they would think it is a very silly thing to do.

My suggestion is less whining from the community about specific aircraft performance to fit an agenda and more enjoyment of the game.
