Datum Plane
The Datum Plane (OP) is a plane which is normal to the airplane's longitudinal axis and
in
front
of
the airplane as seen from the direction offlight. The airplane's longitudinal axis
is para
li
el
with the floor
of
the nose baggage compartment. Wh
en
the floor
of
the nose
baggage compartment is aligned horizontally, the Datum Plane is vertical. The Datum
Plane is located 2.196 meters (86.46 in) forward
of
the most forward point
of
the root rib
on the stub wing (refer
to
figure
in
Section 6.2).
Center
of
Gravity Limitations
The center
of
gravity (CG position) for flight conditions must be between the following
limits:
Most forward flight CG:
2.35 m (92.52 in) aft
of
Datum Plane at 1250
kg
(27561b}
2.35 m (92.52 in) aft
of
Datum Plane at 1468
kg
(32361b)
2.40 m (94.49 in) aft
of
Datum Plane at max. take-off mass (see Section 2.7)
linear variation
in
between
Most rearward flight CG:
2.42 m (95.28 in) aft
of
Datum Plane at 1250
kg
(27561b}
2.49 m (98.03 in) aft
of
Datum Plane at 1600
kg
(35271b}
2.49 m (98.03 in) aft
of
Datum Plane at max. take-off mass (see Section 2.7)
linear variation
in
between
Refer to Section 6.4.4 for a graphical illustration
of
the CG limitations.
WARNING
Exceeding the center
of
gravity limitations reduces the
controllability and stability
of
the airplane.
