Cessna 172RWeight & Balance FAQ
How do I calculate weight and balance for the Cessna 172R Skyhawk?
Start with your specific aircraft's basic empty weight and empty-weight arm from its individual weight and balance record — not a generic POH number. Add each loading station (pilot, passengers, baggage, fuel) multiplied by its arm to get the moment, total the weights and moments, then divide total moment by total weight for the CG. This calculator has the Cessna 172R's station arms and CG envelope built in, so you only enter weights and fuel and it plots the result on the approved envelope. Always confirm against your aircraft's POH before flight.
What is the maximum takeoff weight of the Cessna 172R Skyhawk?
The Cessna 172R has a maximum takeoff weight of 2,450 lb and a maximum ramp weight of 2,463 lb, leaving roughly 13 lb for taxi and run-up fuel. These are representative type values — verify the limits for your specific airframe and equipment in its POH and weight and balance record.
What is the CG range of the Cessna 172R Skyhawk?
The normal-category center-of-gravity envelope for the Cessna 172R runs from about 35 in to 47.3 in aft of datum, with the forward limit typically moving aft as weight increases. Loading outside this range degrades stability and control, so this calculator plots your zero-fuel, takeoff, and landing CG against the envelope and flags any point that falls outside it. Always verify against the CG chart in your aircraft's POH.
How much fuel does the Cessna 172R Skyhawk hold and what does it weigh?
This Cessna 172R profile uses 53 gallons of usable fuel, which at the standard 6 lb per US gallon for avgas weighs about 318 lb. The calculator lets you plan takeoff, trip, and reserve fuel so you can check the center of gravity at zero-fuel, takeoff, and landing — the CG shifts as fuel burns off. Confirm your aircraft's usable fuel and fuel arm in its POH.
This Cessna 172Rweight and balance calculator is provided for educational and reference purposes only. Preset station arms, CG envelopes, and weight limits are representative type values and may not match your specific aircraft. Always refer to your aircraft's official POH/AFM and individual weight and balance record for authoritative data, and confirm the loading is within limits before every flight.
