Just wanted to post and say thanks for the all testing IvanK, always nice to see how the current simulated ac in CoD perform against real data.

Thats some lateral thinking Bongodriver but worthy of a mention to the devs .... Done.

Yes the QNH is strange, given that during the battle the QNH didn't often go below 1005.

Why ?

The International Standard Atmosphere (ISA) lapse rate is 1.98 deg C per 1000 feet !
I miss read your FTH and thought it might line it up better.

Your raw test data FTH aligns with the data converted to standard. In otherwords, the game is showing the FTH to be 17,500 ft, without conversion right?

If that is the case, the atmospheric conditions in the game are standard.

What was your Vy in the test, too?

Its a SPEED test not a climb test so what is the relevance of Vy. As discussed in the in the initial thread these are level speed runs looking for max TAS at each altitude tested.

OOPS, I was locked on the altitude you found FTH and started thinking climb for some reason.

Look guy, I did not ask for the TAS. I wanted to confirm that you did not convert the FTH data from your test to standard conditions.

Is the raw data showing the FTH to be 17,500 ft?

If it is then that is definative proof the atmospheric model is not agreeing with the Flight Models.

FTH is a function of density altitude. Your supercharger does not care what your altimeter reads.

Rather than using terms like "Look Guy" ... (pull your head in by the way ). I tactfully suggest you read the posts carefully before flying of on a tangent and throwing your two bobs worth in.

So far in the Spit and Hurris speed test threads the 3 tangents you have gone off on are:

1. Suggested using the dry Adiabatic lapse rates instead of the ISA Lapse rate.
2. Asked about Vy speed in a level speed test.
3. Suggested that airfield field elevations varied with pressure.

I clearly stated in all the posts no adjustments were made to standard conditions the data is as it is. I also indicated in the Spit test post the FTH quoted was as stated the Altitude at which during the Speed run I first noticed the Boost drooping off. So in the test case was the Rammed FTH. As I indicated in the Spit test no attempt at converting to a standard atmosphere was made ... and I invited anyone who wanted to to go for it !
