I was doing some research on the internet with regard to the performance of the 190's... Primarily because everything I've ever read says that EVERY 190 out matches any Spitfire upto MkIX. However in AHII this does not seem to be the case.
One area that I've always believed the 190's are under modeled is sustained turn performance, however I was not able to find any hard numeric data to support my belief.
I don't know if the data I found is 100% accurate, but I looked at various different sites and was able to establish an average.
The fuel consumption seems to be the biggest variance.
For my testing, I loaded the lightest gun load, emptied the magazines on the runway. Climb performance measured at 100% fuel. Fuel calculations done immediately upon arrival at target altitude and the miles and fuel burn during the climb we're averaged out for level burn at altitude to avoid skewing the numbers. After the testing at 15,750 was complete I made a military climb to ceiling.
General Concensus seems to indicate the A8 gave these numbers:
(blue is real plane, red is AHII model)
Top Speed
Real Life: 404mph @ 15,750 feet (wep unknown, assumed off as most tests are at military power)
AHII: 393mph @ 15,750 (required wep to attain this speed)
Range:
Combat Radius: 530 miles
One way: 1100 miles
Combat Radius: 325 miles (measured at 15,750 feet, 2100RPM and MP 32.9 burn rate 1x)
One way: 653 miles
Rate of Climb (sea level):
3280 Feet per minute (sustained military - no wep)
2700 Feet per Minute (sustained military - no wep)
3200 Feet per minute (Wep on)
Service Ceiling
37,400 Feet
38,050 Feet
