(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.
R EFF : 151-199, 301-399, 401-499, 08-10-00Page 610 Aug 01/05 CES 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:
54.97 RV - 400.26 RA
CG (% RC) = -------------------W
(e) Lower the aircraft on its wheels (Ref. TASK 07-11-00-586-002).
(2)
Weigh the aircraft on its wheels and calculate the position of the center of gravity.
(a) 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).
(3)
Weigh the aircraft on landing gear jacks and calculate the position of the center of gravity.
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
-33400 daN min. at main landing gear
(a)
Put the jacks and the weighing devices in position.
(b)
Jack up the aircraft (Ref. TASK 07-11-00-582-003).
(c)
Refer to the Weight and Balance Manual to weigh the aircraft and calculate the position of the center of gravity (Ref. WBM 1-80-05).
