DC-10 Range issues

[gigeman]

I was setting up my DC-10-30er's and I realized that the range is remarkably low. The game shows it as 4,833 mi but in reality it is closer to 6,500 mi. Is this a glitch or is there some sort of information I am not taking into account?

Do keep in mind that that the range given on the Boeing site is 6220 statute mile which is the equivalent of 5405 nautical miles, which is what the game is played in.

The remaining difference of some 800 nm I will leave up to Stephen or the rest of the staff.
