FM's the State of Play with empasis on Climb performance.

[Al Schlageter]

250mph IAS at 50 ft is not the same as 250mph IAS at 10,000ft?

[von Brühl]

No, they aren't the same speeds. At 250IAS@50ft, you're pretty close to really going 250, at 10000ft, you're closer to 300mph.

This was another 100 page argument with folks on this forum.

And don't you forget, german plane = km/h NOT mph!

Reducing IAS climb schedules were used in all the climb tests as per source documentation.

Here is the source data used for the Spit II climb. IAS is in actuality in MPH not KNOTS The line under knots is actually a misaligned strikeout line that should be going through the KNOTS label ... as it does on all other pages of the document. Given the test was only done to 16,000ft the IAS reduction was only in the order of 5 MPH and then only in the later portion of the test climb.



As reported previously based on timed climb segments the VSI on the Spitfire and Hurricane is over reading by around 500fpm.

Many thanks IvanK, I have the utmost respect for you and the tests you carried out - I hope that your assessment of the beta FM has been passed on to the devs (if not already noted by them).

What is the weight of the airplanes in the game and those in the flight test's?
