Evening all-I am making a quick little cheat sheet for the larger planes that I fly most frequently.While pulling together my information, I came across something peculiar that I can't put my finger on for sure.The fuel burn is noted as 1200 lbs (first hour) and 1000 lbs for each additional hour.I see the max fuel is 5818 lbs (873 us gal max * 6.6 lbs per gal of kerosene +/- = 5762 lbs)That's pretty close.So 5818 / 1200 = 4.84 hours of flight time.Cruise max at 250 knts (VMo) * 4.84 = 1210 nm rangeEverything I find on line says the max range = 774 +/- miles.I assume that the range is based on a full occupant load? I don't really know how the parameters are set up to determin that range. Taking the Max ZFW of 21,400 - 24,000 MTOW = 2600 lbs left for fuel = 2.4 hours or roughly 250nm * 2.4 = 600nm.So it seems likely that the there is some loading factor, say 96% used to calculate the overall range it puts me right at the 800nm mark.So, the short question, is the Range determined under the assumption of a fully loaded MTOW (including Max ZFW) plane?Thanks-Benjamin
