A weight and balance calculator for the GA-8 Airvan, normal and turbocharged versions. This is the Imperial app, for metric weights please find the GA-8 Metric app. 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. Seat position arms are locked. This app has entries for the cargo pod if installed.
Bonus material! A quick reference for the aircraft V-speeds and other interesting aircraft specific numbers.
