I acknowledge that there can be problems with aircraft speed.

Some of that can be simply traced to different sources quote different speed

Some of that can be traced to early OOB work where definitive sources were not always readily available and the speed was guessed at ( or typically ....."X is 5 and this was faster so lets give it 6" ). The rule laid down in MOBHack help were written after this was discovered to be a problem but the problem is pervasive

That said what we are dealing with in this game is primarily ground attack and ground attack typically takes place near the ground so performace at sea level should be the speeds used even though it's sometimes difficult to find that. Typically you get a maximum speed rating and that's "good enough"

The fairey battle for example....... we had 5 and that would represent an aircraft that can fly between 450 and 549 kph

one source http://desertwar.net/fairey-battle.html claims

Its maximum speed at sea level was only 335 km / h

That's a 3 in game terms

I have found no source that claims the Battle could fly at a speed that would justify a 5 so a 3 or 4 would be more correct with 3 being "most correct" in game terms in the context of a ground attack aircraft

Now....... that's just one example of hundreds. We have 11 "P-47's" in the game 1 is rated 6 speed, the others 8. 8 is way wrong. 8 represents an aircraft that can fly between 750 and 849 km/h. The only way a P-47 could go that fast is if they were plummeting to earth wingless with the throttle to the firewall and even then it's iffy.

What this all means is now I have " review all aircraft speeds " on my to do list and what that means is this year the chances are dealing with all the error reports I have recorded to date and getting ALL of them in the game are approaching slim to none. ( which means some of you really need to find something else to do for the next few months ...... my PLATE IS FULL)

That said as a rule of thumb I would suggest that since generally only top speeds are given in sources ( unless they are really good sources.. ) and those top speeds are only achieved at altitudes much higher than ground attack operate that whatever the "top" speed is it should be one less in the game for ground attack and I know I'm opening up my own can-o-worms with that but it also must be remembered that if the speeds 5 or 7 there's really not a whole lot of difference once the variables the game runs on are tossed in......... but YES, it would appear than in the game now aircraft speeds are generally "optimistic" based on the rules in MOBHack and I will be reviewing them as best I can

For those interesting in things like this .........

http://www.wwiiaircraftperformance.org/

is a very interesting source that contains a lot of data such as.."Spitfire Mk IX versus Me 109 G " that has not only some excellent photos but detailed performance graphs that shows that the difference between low level performance and "Maximum" performance in those two aircrafts is about 100 kph. The Spit in this example tops out around 415 MPH ( 668 kmh ) but it's on the deck performance is just below 350 mph ( 555 kph )so what would be a 7 in game should be 6 ( we give it 7 so in the ballpark )
this report........


Unit 400 & 401: max. speed 688 km/h = Speed 7

falls in line with the 695 km/h, 687 km/h and 708 km/h quotes I found but the above source gives this..


High Speed at S.L. 345 mph

.......and that's 555 kmh and that equals 6 in game speed

So yes, the 8 we have now is wrong and is on the list to be corrected but for ground attack....... what they are used for in the game.......... 6 is closer to "reality"
