  1. 3667. (Refer to Figures 33 nd 34.) Calculate the weight and balance and determine if the CG and the weight of the airplane are within limits . Front seat Occupants 350 lb. Rear seat Occupants 325 lb. Baggage 27 lb. Fuel 35 gal. A. CG 81.7, out of limits forward. B. CG 83.4, within limits C. CG 84.1, within limits

  2. Weight and Balance Calculations Weight ARM Moment Empty weight Pilot & Front Passenger Rear Passengers Baggage area 1 Baggage area 2 Fuel main tanks Fuel Aux tanks Oil Total CG = Moment / Weight

  3. Weight and Balance Calculations Empty weight Pilot & Front Passenger Rear Passengers Baggage area 1 Baggage area 2 Fuel main tanks Fuel Aux tanks Oil Total CG = Moment / Weight Weight ARM Moment Front seat occupants............................................ Rear seat occupants............................................ Fuel...................................................................... Baggage …………………………………………… 27 lb 350 lb 325 lb 35 gal

  4. Weight and Balance Calculations Empty weight Pilot & Front Passenger Rear Passengers Baggage area 1 Baggage area 2 Fuel main tanks (35) Fuel Aux tanks Oil Total CG = Moment / Weight Weight ARM Moment 1554 x 100 = 155400 2015 155400 350 325 27 210 0 2927 Front seat occupants............................................
