A weight and balance calculator for the Cessna 150M with long range fuel tanks! Enter the weight (in pounds) for each position in the aircraft, and the amount of fuel (in gallons), and the calculator will let you know if you are out of limits on weight or CG. The forward and aft CG limits are calculated using formula derived from the aircraft limit chart. (If you have a C150M with standard fuel tanks, please use the C150M calculator, as the fuel arms are different)
