4) Aircraft center of gravity (C.G.) calculation
a) Calculate the weighed weight.
b) Calculate the distance from the C.G. to the reference using the formula - see Figure 201 :
(c x pl)
d = b
c) Record the weight and lever arm values in the table below.
d) Calculate the moment by multiplying the weight by the lever arm value and record the result in the corresponding box of the table below.
e) Correct the weights and C.G. as necessary if equipment items were removed prior to weighing -refer to Section 6 of Pilot's Operating Handbook.
f) Add the weights in the weights column to obtain the empty weight.
CAUTION : PAY SPECIAL ATTENTION TO NEGATIVE MOMENTS
g) Add the moments in the moments column to obtain the empty aircraft moment.
h) Divide the moment by the weight to obtain the empty aircraft lever arm.

C. Reconditioning
1) In case of leveling with the jacks, lower the aircraft to ground and remove the jacks - refer to 07-10-00.
2) In case of leveling without the jacks, inflate the tires - refer to 12-14-01.
3) Remove the scales.
4) Replenish the fuel tanks - refer to 12-11-01.
5) Make sure all the tools and materials are removed and the work area is clean and free from debris.
D. Weighing report (Figure 201)
After each weighing, draft a weighing report which must be kept with aircraft documents.
