This calculator is presented for educational purposes only. You, as pilot in command, are solely responsible for assuring correct data and proper loading of your aircraft prior to flight.

• Empty weight and C.G. data comes from your AC current weight & balance records.
  
  
• Station arms, load limits, and airspeed limits come from the Airplane Flight Manual (before 03-01-79) or Pilot's Operating Handbook [POH] (after 03-01-79) [pop-up more detail], or the FAA Type Certificate Data Sheet (TCDS). Downloading the TCDS is recommended to learn more about your AC.
