I have just flown the leg M037 in the Cessna Citation, it should be from GLRB to Z05N, however as Z05N does not appear to exist , I flew to Z04X in Brazil. The statistics for the flight were as follows: Fuel at start 3256 lbs, Fuel on landing 891 lbs, distance flown 2053nm, the engines were burning 250lbs/hour each at FL360. These figures don't seem to be correct for a Cessna Citation, as it is supposed to have a range of 1250nm, as you can see from the above figures I have flown 2053nm with still enough fuel for another 1 hour flying time.
