18. Find arms of right and left seats from POH p. 6-6
19. Multiply Weights x Arms to find moments of right and left seats
20. Total moments
21. Divide total moments by total weight to find A/C CG zero fuel
22. Find arms of fuels from POH p. 6-6
23. Multiply Weights x Arms to find moments of fuels
24. Total moments
25. Divide total moment by total weight to find A/C CG full fuel
26. Graph in POH p. 2-6.1

A/C = Aircraft
POH = Pilot's Operating Handbook
CG = Center of Gravity

Weight x Arm = Moment

Moment / Weight = CG

Basic Empty Weight includes oil and unusable fuel
