We went Dallas to Vegas and fought a 80-120 wind off the nose the entire time, 3:10 en route and landed with roughly 900lbs, so the fuel was getting low but still had a good :45-1 hour. 31A holds a total of 4132lbs with number of 1,500 1,200 800 800 for the 1-4th hour, but in my experience you don't get 4 hours out of her. When we are leveled in cruise at 41-43 we burn around 550 a side, but we keep the power up a bit to hold .78 or so instead of sacrificing speed to get 800lbs an hour. Someone can correct me if I'm wrong but a beech jet cant hold but a few passengers and crew at full fuel.
