Speed graphs for Spitfire and Hurricane

[SEE]

Thank you BS, but I am confused why the devs have generally reduced the Spit Mk1a speed in the next patch given that it is already slower than the flight test data?

I don't understand that at all.

Because devs fly blue, maybe ?

These graphs only show performance from 2000/3000m and up, whereas the previous graphs showed performance from 0m and up.

It's very interesting to note that between 3000 and 5000m, the patched 109E4 performs better than RL, whereas both the Rotol Hurri and the MkIa Spitfire perform worse than RL at these altitudes.

Please can we see graphs for the Spits and Hurris from 0m and up, so we can make a true comparison?

Many Thanks.

We don't have official flight tests for Spits and Hurris between 0 and 3000m.

Thanks, Black Six. At last we finally know why the Spitfire Ia's top speed at sea level is 240 mph. The slope of the curve was simply applied to the 0 - 3000 m gap in information, so 0 feet = 240 mph. Mystery solved.

This chart gives speed down to 0 feet. I think it's calculated as the test log only goes down to 3000 m.

Thanks, Banks. That chart squares very closely to what we all KNOW how a Spitfire Ia performs at sea level. The vast majority of dogfights on the ATAG Server occur well below 3000 meters, including those that start above that mark inevitably descend well below it.

For a year the CoD RAF fighters (save the IIa) have been saddled with poor low altitude performance, with the only fighter, the Spitfire IIa the only one which comes close to historical performance at low altitude (300 mph at sea level vs 290 mph historically). Yet in the face of stiff opposition by many of those who fly 109's, the IIa was either excluded or severely limited in the ATAG plane sets. Now we've been advised that the IIa will be nerfed in the upcoming patch by as much as 60 mph at some point(s) on the speed curve. In view of the Rotol and Ia information, confidence by many who choose to fly RAF fighters is very low that correct flight modelling for all three models (Ia, IIa, Hurricane Rotol/Ia) will actually be done in this upcoming patch.

All many of want is an ACCURATE representation of ALL fighter flight models for BOTH sides. The Spitfire Ia was considered a serious threat by Luftwaffe 109 pilots during the Battle of Britain at ALL altitudes. In Cliffs of Dover, the "Sissyfire" Ia is a cruel joke that has lasted over a year -- anyone who plays Cliffs of Dover doesn't need performance charts to realize that. Why can't the devs see that?????

More correctly: we didn't have official flight tests for Spits and Hurris between 0 and 3000m for this test.
I don't know how our FM programmer made this planes for game in 2011.

Thanks, Black Six. I think we've got it figured out.

This page gives sea level to 29,000 feet figures for the Spitfire with Merlin III @ 6.25lbs boost:

and this gives it for the Hurricane:
http://www.wwiiaircraftperformance.o...rricane-I.html

I've placed your Patch Data on top of these and projected the sea level speeds (see attached) and both are looking too slow from sea level to 20k and 16k respectively. At sea level the Spitfire is looking to be 255mph instead of 283mph (28mph slow) and the Hurricane 240mph instead of 262mph (22mph slow).

Can you please confirm that the patch FM is still being adjusted to RL data (or that it will be)?
