Always follow these guidelines: 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. There is no flight engineer on the aircraft.
This acts as a buffer between the cable and the floor. Cushioning material, packing, cellulose, longitudinally compressed, NSN They must have a thorough knowledge of their equipment the crew of the aircraft is responsible for the loading of the aircraft.

fk Inspect pallets and nets to assure serviceability. The greatest rotor wash velocity occurs between 20 to 60 feet outside the rotor disc. The cargo nets are installed on stacks of general cargo as follows: 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.
It consists of an adjustable nook, tension collar, chain lock, a quick-release lever, and a 9- foot steel cha in with an L-shaped hook on one end Figure In use, the 55-4450-2 hook end of the chain is passed over the load, and the hook is then engaged with a link of chain. The pod has a reinforced tread 55–450-2 that will hold equipment as heavy as a 12,pound howitzer. The correct method is to pass the hook end over and brine it up under the tie-down point.
This action aids unloading the pod by allowing the use of a forklift and other cargo-moving equipment. If this is not possible, follow the procedures tm in the sample problem in paragraph A complete description of the pallet, cargo nets, and instructions for their use are in Chap- ter 3. WARNING To reduce the possibility either of injury to ground crew personnel from flying debris or of an accident resulting from debris being drawn up into the helicopter rotor blades, police the operational area thoroughly.
Make certain that all components are accounted for in either the in- stalled or stowed locations as applicable. Place one block to the side of the aircraft to permit unobstructed passage of the winch or tow caole out of the aircraft.
Vertical restraint up formula: The pod can be loaded on the ground and then raised up to the helicopter. However, weight and CG requirements must be within limits. Nothing can be added to or removed from 55-450-22 vehicle that has been weighed and marked unless it is reweighed.

It is seldom possible to fasten a tie-down device in this manner. Tie down the container with the number of tie-down devices determined in Step 2. When operating the helicopter at a critical gross weights, use the exact weight of each occupant plus equipment.
The floor provides the downward restraint. Never push or slide L pallets across any solid surface; to do so will cause damage to the skin. A successful mission must be thoroughly planned and executed by personnel who know the capabilities and limitations or the aircraft, equipment, personnel, and terrain.
Do not plan an internal cargo mission without direct coordination with the supporting aviation unit.
It h olds up to 55-4450-2 combat-equipped troops or 24 litters Figure Always use the same row of rings on the side nets to ensure that the top net pulls evenly. It also protects the cargo floor from damage caused by tracked vehicle cleats, steel wheel rims, and packing case bands or studs.
Before beginning the process, the unit movement officer must make sure that scales used for weighing are calibrated. Use a barrier and chain gat ej Figure for loose, heavy items such as lumber and pipes.
The selection of a usable PZ or LZ is extremely important.

There are presently two models C and D in the inventory. Inspection 1 Inspect textile items before and after each use. It has a four-blade main 60A has an 8,pound load capacity r system. Determine the CB by placing that load onto a pipe and centering the cargo until it balances, then mark your Co.
Make sure that the tie-down fittings are not overloaded. If enough tie-down devices are ap- plied over the top of the cargo to provide forward and lateral restraint, then vertical and aft restraint will automatically be provided.
Plywood sheets of various thicknesses and sizes may be used when practical. To obtain the maximum pod wheel ground clearance of 18 inches when the pod is at- tached to the helicopter, full retraction of the pod wheels is possible.
