A weight and balance calculator for the GA-8 Airvan, normal and turbocharged versions. This is the metric app, for Imperial weights please find the GA-8 Imperial app. Enter the weight (in kilograms) for each position in the aircraft, and the amount of fuel (in liters), 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.
