Section IV. CENTER OF GRAVITY
6-11. CENTER OF GRAVITY LIMITATIONS.
WARNING
When mission gear is removed the
forward center of gravity limit is
easily exceeded.
Center of gravity limitations are expressed in ARM
inches which refers to a positive measurement from the
aircraft's reference datum. The forward CG limit at
12,600 lbs., or less, is 179.0 ARM inches. The forward-
sloping CG limit line is a straight line from 12,600
lbs. to 16,500 lbs, ending at fuselage station 188.7. At
16,500 lbs., or less, the aft CG limit is 195.1 ARM
inches. The Center of Gravity Loading Diagram
(fig. 6-3) is designed to establish forward and aft CG
limitations. When mission gear is removed it may be
necessary to add removable ballast or baggage in the aft
baggage compartment.
Section V. CARGO LOADING
6-12. LOAD PLANNING.
The basic factors to be considered in any
loading situation are as follows:
a.
Cargo shall be arranged to permit access to all
emergency equipment and exits during flight.
b.
Floorboard
structural
capacity
shall
be
considered in the loading of heavy or sharp-edged
containers and equipment. Shorings shall be used to
distribute highly condensed weights evenly over the
cargo areas. Use of the floor seat tracks to support
loads is encouraged where possible.
c.
All cargo shall be adequately secured to prevent
damage to the aircraft, other cargo, or the item itself.
6-13. LOADING PROCEDURE.
NOTE
The cabin airstair door is weight
limited to a maximum of 300 pounds
to
prevent
possible
structural
damage.
Loading of cargo is accomplished through the
cabin door (21.5 in. X 49.0 in.) or the cargo door (52.0
in. X 52.0 in.).
6-14. SECURING LOADS.
All cargo shall be secured with restraints strong
enough to withstand the maximum force exerted in any
direction. The maximum force can be determined by
multiplying the weight of the cargo item by the applicable
load factor. These established load factors (the ratio
between the total force and the weight of the cargo item)
are 1.5 to the side and rear, 3.0 up, 6.6 down, and 9.0
forward. SURVIVABILITY EQUIPMENT.
Section VI. SURVIVABILITY EQUIPMENT
6-15. FLARE AND CHAFF DISPENSERS.
Refer to table 6-2 for flare and chaff dispenser
weight and balance data.
