Please see the Appendix 1.
5.2 Center of gravity (CG) range and determination
Method for determining the Basic Empty Weight
Place the aircraft level on three suitable scales. (If only one scale is available, use
leveling blocks and make separate measurements at each gear location).
The aircraft leveling reference is the top of the console (tunnel) that runs between the
pilot seats.
Note the following measurements:
G1: The weight found at the nose wheel location
G2: The combined weight found at the main wheel locations.
a: 35.63 in. / 905 mm - the distance from the leading edge of the wing to the nose
wheel.
b: 58.07 in. / 1475 mm - the distance from the main gear location to the nose wheel
location.
The Basic empty weight is the total of weights found at G1 and G2
G1 + G2 = G
Using the following formula, find the Empty Center of Gravity location of the aircraft.
((G2 x b): G) – a = X
X - The distance from the leading edge of the wing to the Cg location
Using the weights found on the scales and the weight and balance sheet determine the
Basic Empty Weight.
Complete the Weight & Balance and Equipment List.
Determining the Weight and Balance
Using examples (see Appendix 3), find the loaded center of gravity location.
Using the center of gravity envelope, plot the loaded center of gravity.
