Cessna 172 Weight and Balance Calculator

FAQs

1. How do you calculate the weight and balance of a Cessna?

2. What is the usable weight of a Cessna 172?
   • The usable weight of a Cessna 172 can vary depending on the specific model and modifications, but it’s generally around 800-900 pounds (360-410 kilograms).
3. What is the weight of a Cessna 172?
   • The empty weight of a Cessna 172 can vary by model, but it’s approximately 1,650-1,750 pounds (750-790 kilograms).
4. Where can I find my aircraft weight and balance?
   • You can find the weight and balance information for your specific Cessna 172 in its aircraft operating handbook (POH) or the aircraft’s weight and balance manual.
5. How do you manually calculate weight and balance?
   • To manually calculate weight and balance, you need to gather the weight of the aircraft, passengers, cargo, and fuel. Then, you calculate the moment (weight multiplied by arm) for each item and sum them up to determine the total moment. Finally, you divide the total moment by the total weight to find the center of gravity (CG).
