Checking of the empty wei~ht C.G. position
To facilitate the checking of the empty
weight C.G. position by weighing the glider
at the tail skid (with fuselage in horizontal
position i.e. main landing wheel on the
ground and tail skid jacked up about 42 cm,
16.5 in. from the ground), the following
table shows the permitted maximum weight at
the tail skid for different empty weights
incl. equipment. If these tail weights,
calculated for the corresponding limits of
the extended aft empty wei~ht C.G., are not
exceeded it is certain that the empty weight
C.G. position is within the limits.
W(e) - Empty weight incl. equipment
CG(a) - Extended aft empty weight C.G.
(calculated for a min. front cockpit
load of 70 kg, 154.3 lbs.)
