6-4-2. Personnel Weight Computation.

plus equipment should be used. If weighing facilities are
not available, or if the tactical situation dictates other-
wise, loads shall be computed as follows:
a.
Combat equipped soldiers 240 pounds per indi-
vidual.
b.
Combat equipped paratroopers 260 pounds
per individual.
c.
Litter patient (including litter, splints, etc.) 200
pounds per individual.
d.
Medical attendants 200 pounds per individual.
e.
Crew and passengers with no equipment Com-
pute weight according to each individuals estimate.
f.
Refer to figure 6-4-1 or 6-4-2 for personnel or litter
patient moment data. The chart (fig. 6-4-1) provides pre-
computed moments for each troop seat position.
6-4-3. Seating Arrangement.
Seating arrangement for 33 fully equipped ground troops
is provided by ten 3-man seats and three 1-man seats
(fig. 6-4-3). A row of five 3-man seats is installed along
each side of the cargo compartment. One-man seats are
installed at the forward and aft ends of the left-hand row
of seats and one at the end of the right-hand row of seats.
6-4-4. Troop Seats.
These seats are made of nylon on tubular aluminum
frames and are joined together for greater rigidity and
comfort. The seats are joined by means of slide bolt
fasteners in the front seat tubes, zipper fasteners on the
underside of the seat fabric, and snap fasteners along
the vertical edges of the seat-back rests. A slide adjuster
below the back rest hanger clips affords adjustment of
back rest tension. Seat tension is adjusted by relocating
retaining pins in the holes drilled in the front seat tubes.
A row of male snap fastener studs along the rear of the
seat-back rest matches a row of female snap fastener
sockets along the rear edge of the seat fabric. These
fasteners are jointed to provide greater seat depth for
troops equipped with parachutes. Two stowage straps
are attached to the underside of the seat fabric; one is
equipped with a hanger clip for folded stowage, the other
is equipped with a buckle for rolled stowage. The seats
will normally be stowed in the folded position for cargo
transport.
A 2,000-pound-capacity nylon web safety belt is pro-
vided for each seat occupant. The belt is adjustable and
is equipped with a positive-grip buckle fastener designed
for quick release.
6-4-5. Troop Seat Installation.
Install the troop seats from the rolled position as shown
in figure 6-4-4. Install troop seats from the folded position
by performing steps 1, 4, 6, and 7 of figure 6-4-4.
6-4-6. Troop Seat Stowage.
Stow the troop seats in the rolled position by performing
steps 1 through 9 in reverse order as set forth in figure
6-4-4. Stow troop seats in the folded position by revers-
ing the procedures in steps 7, 6, 4, and 1 of figure 6-4-4.
6-4-7. Troop Loading.
6-4-8. The loading and unloading of troops will normally
be accomplished through the lowered aft cargo door and
ramp. The most orderly and efficient troop loading proce-
dure is for the troops to occupy from the front to the rear.
In unloading, the troops will leave the helicopter progres-
sively from the rear to the front. If the troops to be loaded
are carrying full field equipment, it is recommended that
the seat-back rests be folded to avoid entanglement with
the equipment and damage to the seat-back rests.
6-4-9. Troop Commanders Jump Seat.
A collapsible fold-away seat is located in the cockpit en-
trance for the use of the troop commander. The seat is
made of nylon on a tubular aluminum frame.
6-4-10. Litter Arrangement.
There are provisions for 24 litters, three tiers, four high,
along each cargo compartment wall normally occupied
by troop seats (fig. 6-4-3). The two 1-man seats in the aft
section of the cargo compartment may remain in place to
serve as seats for medical attendants. If needed, the
1-man seat in the forward section of the cargo compart-
ment may also remain. It is not necessary to remove the
troop seats to install the litters.
