Weight and Balance Information 4 - 3
4.3 Center of Gravity Range and Determination
To determine “CG”, put the aircraft on 3 weighing scales, positioned
on a level surface. Before weighing, a level wing main chord has to
be established (use pads between main wheels and scale beneath).
A check-mark (R.P.) on the leading edge of the left wing, adjacent to
the wing root is provided to ease examination to level wing main
chord - use a flexible clear hose, filled with water as a spirit level.
The total weight G = G1 + G2, has to be used for calculating “CG”,
located at the distance “X” behind R.P.
