A weight and balance calculator for the Cessna 150G 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. This calculator is for the C150G with long range tanks- if your aircraft has standard tanks use the C150G app as the fuel arms are different. This calculator was developed for the C150G model; however, the aircraft did not change through the C150L model. But, before using this for any model other than the C150G check the position arms.
