u. Add total moments in blocks 30, 31, and 32 (if any) and record sum (basic aircraft moment) in block 33.
v. Divide block 33 (basic aircraft moment) by block 25 (basic aircraft net weight) and record result (center
of gravity ARM) in block 28.
w. Divide block 33 (basic aircraft moment) by 100 and record result (moment/100) in block 34.
x. Enter the following statements in block 21 (remarks):
(1) “Helicopter weighed on jacks: 3.5 Nose-Up Attitude”.
(2) “Basic weight corrected to 0 (Level Attitude)”.
