SECTION II - RIGGING AAFARS WITH FOUR 500-GALLON FUEL DRUMS
DESCRIPTION OF LOAD
4-20. The Advanced Aviation Forward Area Refueling System (AAFARS) is
rigged on a 20-foot, type V airdrop platform with five G-11 parachutes. The
AAFARS is designed for forward area refueling of up to four aircraft at a time
with a minimum output of 55 GPM. There are four collapsible fuel drums as an
accompanying load. Each drum is filled with 432 gallons of liquid. When empty,
each drum weighs 250 pounds and is 62 inches long and 53 inches in diameter.
The overall length of the load is 258 inches. The load is 88 inches high. Its
center of balance is 121 inches.
Notes:
1. For drums filled with a liquid other than water, use Table 1-1 to
recompute the weight.
2. If the load varies from the one shown, the weight, height, CB, tipoff
curve, and parachute requirements must be recomputed.
3. Do not pressurize drums with air.
PREPARING PLATFORM
4-21. Prepare a 20-foot type V airdrop platform using two tandem links, eight
suspension brackets and 62 tie-down clevises as shown in Figure 4-36.
Notes: 1. The nose bumper may or may not be installed.
2. Measurements given in this section are from the front edge of the
platform, NOT from the front edge of the nose bumper.
