Their primary mission is to provide navigational assistance and control to Army aircraft in areas designated by the supported unit. The rules used when applying tie- down devices to cargo with tie-down provisions are as follows: The shipping container shown weighs 1, pounds Figure Finally, use 5,pound tie-down straps, as required, to provide individual item restraint Figure 1 or to provide supplemental restraint figure 1 to the L nets. Place a plastic barrier between 55-405-2 and the bottom pallet to prevent moisture from penetrat- ing through dunnage to bottom surface of pallets.
In the vehicular tread area, the maximum allowable floor loading is 1, psf. Two people should do this to ensure that the net stays even. Grata cut to 1ioott.

Two Tie-Down Chains Method 2. There would be no laterafor vertical restraint from this device since the cargo can readily move in these directions.
Keep the hook to the left side of t the hoo! When cargo is restrained in this manner, the fol- lowing factors must always be kept in mind.
The device applied across the front of the cargo will only provide restraint in the forward direction since it is trie only directio n in which it really preve nts the cargo from moving Figure Detail B. Additionally, assure that the scaled weight is clearly marked on each side 88 inch of the 4b3L pallet. The correct method to attach the hook end to a perpen- dicular tie-down provision is to pass the hook end from the left through or around the tie-down provision and bring it hack under the running end of FM FIGURE They must be able to operate the equipment, position it in the helicopter cargo compartment, set hand brakes, and when applicable, leave gears engaged for parking.
It is also used for training, mobilization, medical evacuation Figureand development of new and improved concepts. The AHD is the smallest helicopter and has the lowest lift capacity.
When the helicopter lands, this charge passes to the ground through the helicopter grounding system. When the ramp is-lowered, these auxiliary ramps provide flush contact between the ramp and the ground.
A helicopter crew member operates the winch. Use a barrier and chain gat ej Figure for loose, heavy items such as lumber and pipes.
Repeated or prolonged inhalation of the solvent vapors can be detrimental to human health. Its mission includes transporting troops, cargo, or patients.
Litter patient including litter, splints, and so forth: For more infor- mation on shoring, see paragraph They also supply vertical and lateral restraint. Litter patients including litter, splints, and so forth: It can also support portions of a cargo load that exceed the longitudinal dimensions of the cargo floor. If tie-down fittings 55-45-02 not located to allow longer barrier net straps toward the front of the load for forward restraint, attach to the next available tie-down fitting aft.
Now measure 77 inches from the tongue aft to obtain the CB on the trailer. They have a load capacity of 5, pounds each.
Attach the helicopter winch cable hook to both chains in the center of the bridle. It holds up to 45 combat-equipped troops or 24 litters Figure Determine the minimum number of tie-down devices necessary for the required restraint.
When tie-dow n devices are passed over cargo from side to side [Figure Detail C]the tie-down device should be as close to yu degrees as the floor fittings will permit.
If tie-down devices are applied across the cargo, the restraint in each direc- tion should be checked if there is any question. Sign In Sign Out.

The spacing of the fittings is a standard inch grid pattern. Restrain all cargo to ensure safe operation of the aircraft and the safety of personnel.
A utility helicopter is a general-purpose aircraft that has limited carrying capability. The netting material will mildew and deteriorate. Since the tie-down devices are not actually attached to the cargo, make sure that the load cannot slip from under the tie-down device. Cargo with no tie-down provisions is restrained by passing the tie-down straps over or around the cargo and attaching both ends of the tie-down device to the tie-down fittings in the cargo floor.
The length of this ribbon the width of the tire then becomes important in calculating load distribution.

The ramp- toe extension is usually made of 2- x inch lumber Figure ‘ b. Shoring is a method of using lumber, planking, or similar material to spread highly 55-45-2 loads over a greater floor area than that occupied by the cargo alone.
Each tie-down has a rated strength, which is the load or force it is designed to withstand. FM also contains details on the selection and marking of PZs and procedures that should be used to control the aircraft. This procedure is particularly important when tying down tall items and composite cargo loads consisting of several stacked boxes. While hold- ing the webbing, operate the handle with a rocking motion to tighten the spool. Knowing these procedures will simplify some or the loading you will be involved in.
When the litters are installed, there is still room for 15 seats down the middle for ambulatory patients, attendants, or troops. Tie-down devices secure cargo against forward, rearward, lateral, and vertical movement during takeoff, flight, and landing. Storage 1 Store all textile items in a dry area, protected from direct sunlight, in a manner to 555-450-2 contact wit h sharp or abrasive objects and the ground.
Unit commanders should train selected groups of personnel on helicopter operations. Make sure that the tie-down fittings are not overloaded.
