USE OF WEIGHT AND BALANCE DIAGRAM
1. Calculate the weight of the fully loaded aircraft:
Empty weight (from the Weight & Balance Data Sheet)
+ pilot and passengers weights
+ baggage weight
+ standard fuel (1 liter JET A-1 = 0.81 kg)
Make sure that the total weight does not exceed 980 kg
(2161 lb) in cat. N and 910 kg (2006 lb) in cat. U.
2. Place the empty aircraft moment (from the Weight and Balance Data
Sheet) on the upper scale of the diagram, and proceed with your own
data as in the following example, indicated by dashed line on the
diagram.
Loading is acceptable when the resulting point falls within the C of G
moment envelope (white area).
Example of loading problem (dashed line on the diagram)
Licensed empty moment (sample airplane)............................ (1548 ft.lb)
214m.kg
Weight of the empty aircraft ........................................... (1323 lb) 600 kg
Pilot & front passenger..................................................... (331 lb) 150 kg
Rear passenger ................................................................. (198 lb) 90 kg
Fuel, main tank 77.4 L (20.4 US gal) .................................. (143lb) 65 kg
Baggage ............................................................................ (37.5 lb) 17 kg
TOTAL WEIGHT ........................................................... (2033 lb) 922 kg
Centre of gravity within the envelope.
1 liter JET A-1or Diesel .................................................. 0.81 kg (1.79 lb)
1 imp gal JET A-1 .......................................................... 3.69 kg (8.13 lb)
1 US gal JET A-1 ........................................................... 3.07 kg (6.77 lb)
