Our company i looking at a Beechjet to supplement our shorter trips so we don't have to take the Challenger and eat up gas. The one we are looking at weighs 11000 BOW and by my calc. you can only go about 1:15 with full pax at max TO weight. That's using 30 min to alternate and 45 min thereafter! Am I missing something? At the end of hour one you only have about 2300 lbs aboard. I would like to be at my destination in hard IFR with 2000 lbs. Are there any good points?
