Mathematical Formulas & CG Equation
Moment (lb-in) = Weight (lbs) × Arm Station (in)
Total Moment = Σ(Weight_i × Arm_i) = 89,525 lb-in
Center of Gravity (CG) = Total Moment ÷ Total Weight = 39.79 in
Cessna 172S normal category envelope requires Total Weight ≤ 2,550 lbs and CG between 35.0" and 47.3" aft of datum.
Why Weight & Balance Matters: Overloading or placing the CG too far aft can result in unstable pitch control, reduced stall recovery capability, or structural failure.
