PA-31-350 Weight and Balance Calculator

A weight and balance calculator for the Piper Navajo PA-31-350. Tabs are available for Executive, Commuter, and Cargo Only configurations. Entries for both inboard and outboard fuel tanks are available.

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. Correct cargo and bag loading is verified.

If proposed fuel burn is entered (in gallons), a landing CG check is performed. Burn for both the inboard and outboard tanks should be entered. Proper cargo loading positions are also checked- overloads give alert messages and are flagged.

Bonus material! A quick reference for the aircraft V-speeds and other interesting aircraft specific numbers
