A. Weigh the Aircraft and Calculate the Position of the Center of Gravity NOTE : You can weigh the aircraft with:
____
-
the aircraft on jacks
-
the aircraft on its wheels
-
the aircraft on landing gear jacks
EFF : ALL 08-10-00Page 606 May 01/05 CES
(1) Weigh the aircraft on jacks and calculate the position of the center of gravity.
NOTE : To weigh the aircraft on jacks, the aircraft must have a pitch
____
attitude of zero deg..
NOTE : You can refer to the Weight and Balance Manual to weigh the
____ aircraft and calculate the position of the center of gravity (Ref. WBM 1-80-04).
NOTE : You can do this procedure with load cells on each jack or with
____ platform scales under each jack. The load cells or the platform scales must have a capacity of:
-7000 daN min. at nose landing gear
-30000 daN min. at main landing gear
(a)
Put the jacks and the weighing devices in position.
(b)
Jack up the aircraft and make the aircraft level (Ref. TASK 08-21-00-200-001).
(c)
Calculate the aircraft weight W: W = RA + RV
W = aircraft weight
RA = reaction that you measure at the forward jack point.
NOTE : If you use platform scales, you must subtract the weight
____
of the jack.
RV = sum of the reactions that you measure at the wing jack
points.
NOTE : If you use platform scales, you must subtract the weight
____
of the jacks.
RC = Reference Chord
(d) Calculate the position of the center of gravity.
To do this, use the formula:
54.98 RV - 298.5 RA
CG (% RC) = -------------------W
(e) Lower the aircraft on its wheels (Ref. TASK 07-11-00-586-002).
