6-11. CABIN AREA.
a. Cabin. The cabin extends from the back of
the cockpit partition to the aft cabin wall. This area
provides 253.0 cubic feet of space. The cabin is 57.0
inches high and 54.0 inches wide. Access is gained
through the entrance door that measures 51.5 inches
high and 26.7 inches wide. The cabin section flooring
will withstand a loading of 200 pounds per square foot
for storage supported on the seat tracks. Floor areas
where seat tracks are not present (walkways and aft
baggage/utility area) will only support 100 pounds per
square foot floor loads. Refer to Section V, to
determine maximum cargo capacity and load position.
Payload shall be limited in conjunction with fuel
loading to stay within the design gross weight
limitations.
b. Seating Arrangement. Seating is provided
for eight passengers. These seats may be installed
facing aft. A side-facing toilet is installed across from
the cabin entrance door, separated from the
passenger area by a partition. A seat belt is provided
and seating of one passenger is allowed in the toilet
area. A baggage storage area is provided in the
farthest aft portion of the cabin. Refer to Figure 6-3 for
baggage moments.
NOTE
The baggage/utility compartment area,
containing 53.3 cubic feet of space,
provides for storage of 550 pounds of
baggage.
c. Ferry Fuel Configuration. The cabin area
may be converted to accommodate ferry missions by
removing the passenger seats and floor panels. The
tank platforms and ferry tanks are secured with seat
rail cargo rings on seat rails. The fuel tanks are
connected to the provisions already installed in the fuel
system.
6-12. PERSONNEL LOADING AND UNLOADING.
a. Seat Installation. The seats are mounted
on full-length seat tracks to provide for quick removal
and various seating arrangements. The armrests
adjacent to the aisle may be lowered to allow ease of
entry. The seats have reclining backs that may be
adjusted for individual comfort. Seat back must be in
the full upright position for takeoff and landing.
b. Seat Belts and Shoulder Harnesses. The
pilot's and copilot's seats are equipped with shoulder
harnesses. The belt for the shoulder harness is in a
"Y" configuration with a single strap contained in an
inertia reel attached to the seat back. One strap is
worn over each shoulder and fastened by metal loops
to the seat belt buckle. Spring loading of the inertia
reel allows normal movement. A locking device will
secure the harness in the event of sudden forward
movement or impact action. Each passenger seat is
equipped with a lap seat belt. An over the shoulder
restraint belt, in addition to the lap belt, is installed on
T2 models.
6-13. PERSONNEL LOAD COMPUTATION.
When aircraft are operated at critical gross
weights, the exact weight of each individual occupant,
plus equipment, should be used. Refer to Figure 6-4
for personnel moments chart. Crew and passengers
with no equipment: compute weight according to each
individual's estimate.
NOTE
Personnel loading configurations other
than those shown in Figure 6-4 shall be
computed using Cargo Moment Chart,
Figure 6-5.
