F-15 PERFORMANCE
-
I’m having a lot of fun in the new F-15, but the lack of a performance chart (like we have on the Mirage-2000, F-16, F-18, Viggen…) make things a little harder.
Is there anyway to consult the performance chart of the BMS F-15?
Thanks!

@VDK Good point
As of today, the answer is: “Not yet”In 4.37 we still have a small concern with wing pylon being included in “basic” 3dmodel, so no one is able to fly a “clean” F-15 and we have had to do some “tuning” and adjustment to map flight model to this situation (for example, max BMS Mach is closer to M2.2 than 2.4+ as it would be for a “clean” RL Eagle)
And BTW, I do not know what are the export restrictions on F-15 performance data, but just for the sake of BMS team not taking such kind of risk, I doubt it will be very clever to “publish” BMS F-15 performance charts.
So, if you have access to RL F-15 performance data, you can try using them and you may report any significant gap (but if you take into account accurate weapons and pylons loaded, BMS should not be that far)

T.O.-1F15-A-1 manual is available, the best what you can get quickly.
To me, the model is enough accurate for a sim, because I can reproduce the climb records of the F-15 Streak Eagle if i set 2800 lb lower weight for the F-15A and the same fuel as happened in RL.
With -15C air temp, the difference between the BMS and RL is within the line thickness. To me this is fine. In fact even the old FM could produce this 11 years ago.

@molnibalage Right, the only thing I’ve really improved with 4.37 F-15 FM in term of performance are
- Drag close to stall (so speed loos at very high AoA)
- Drag between M1.0 and M1.40 (transonic acceleration)
- Drag with load factor lower than 1.0 (Eagle does not accelerate faster when ballistic…)
Most significant is the much better handling provided by Mav-JP dedicated AFM, but performance-wise this has no impact

Thanks for all the answer guys!
