This is a head's up for anyone working on a flight model for FSX that uses an afterburner. I have posted before that FSX with Acceleration does not use jet engine table 1506 the same way that FS9 did. Now I've discovered that FSX SP2 uses 1506 pretty much the same way as FS9. This means you're probably going to need to do two air files for any FSX project.:faint:

Isn't that because of the multi-stage afterburner in XPack?

No, this has nothing to do with multi-stage afterburners. When the mach number exceeds the 1506 table limits in FS9 and FSX SP2, the value returned from table lookup is extrapolated. In FSX Acceleration, the returned 1506 value is truncated to the highest value in the table. This lookup could have (and should have) been done the same way in all versions.
