On the T/O weight....
Standard Takeoff Weight is 15.5k lbs.
Optional weights at 16.5k and 17.0k lbs. FlexJet 31s are 17.0k lbs. for takeoff.
There is a Pilot Training Guide floating around out there (I've got a copy long since corrected) that says max T/O wt is 17.7k. but this is in error. The PTG is a pretty detailed resource but the early versions have some mistakes.
Oh yeah, if you overwing a standard fuel system its 4124 pounds, singlepoint gives you (allegedly) 4019. If you have extended range tanks its supposed to give you an extra 529 lbs,but we don't have those...
AF001, I've got recurrent coming up in just over a month, so keep 'em coming.
