TM 1-1520-240-10            6-4-1 SECTION  IV.  PERSONNEL 6-4-1.  Personnel Loading and Unloading. The  loading  procedures  should  be  accomplished  and observed before loading to ensure the safety and comfort of personnel to be airlifted: a. Passenger compartment – Clean. b. Equipment – Stow and secure. c. Troop seats – Install,as required. d. Litters – Install, as required. e. Static line anchor cable – Install, as required. f. Safety belts – Check, attached. g. Emergency equipment – Check. h. Emergency exits – Inspect. i. Special equipment – Check. 6-4-2.  Personnel Weight Computation. When the helicopter is to be operated at critical gross weights, the exact weight of each individual occupant 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 individual’s 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 Commander’s 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.
