Center of gravity (CG) range and determination
To determine the real weight and the center of gravity, it is required
to follow the descriptions below.

To get the correct values, it is necessary to put the
aircraft on three weighing scales, located on a level
surface. Before conducting the weighing procedure, it is
important to achieve a level wing main chord (use suitable
pads between main wheels and scale beneath to hoist aircraft).
A check-mark (R.P.) on the leading edge of the left wing,
adjacent to the wing root is provided to ease examination that
wing main chord is level - use a flexible clear tube, filled with
water as spirit level. To get the total weight
G
you have to add
value
G1
and
G2
. The center of gravity has to be calculated
using this value. The "CG" located at the distance (X) from R.P.
is measured near the fuselage.
