G550_Opslacky
The fuel capacity of the G550, is 40500Lbs, with a variance of down to 39500, which I would use for LR planning.
There is the next problem, of payload: assume that with full fuel, and a slightly higher BOW then 4 pax is max.
Also baggage space, volume is limited. Tried to take 6 pax, and 26 peices from Luton, to UAE: had to refuse 14 pieces.
Whilst I love the G550, it does not have the volume for this trip.
