What’s wrong here and how do I fix it? According to the specs. for the Beech Baron the range should be about 1569nm or 1807sm. I get 5.76 mpg at 12,000’ with mixture at max flo, propeller at 22 and power at about 20 (max power is around 26.) With 142 gallon capacity this will give me a range of 818sm. Less than half the specs. Can I change this in the aircraft.cfg file some way?
