Figure 2-16. High Bank Launch of Bay (Sheet 12 of 12).
2-17. Deployment By Helicopter. Under certain conditions it may be advantageous to use helicopters to transport
bays. The lifting sling and shackles provided in the supplementary set are to be used to enable four-point suspension.
When transporting in interior bay at an air speed greater then 40 knots, a 15 foot diameter drogue parachute, (NSN
1670-01-063-3715), Type 4 links (NSN 1670-00-783-5988) and 36 foot multi loop extraction line (NSN 1670-01 -064-4451)
are required to provide stability. Safe airlift speed is determined by wind speed and direction, type and condition of aircraft
as well as pilot proficiency in transporting bays.
CAUTION
Unit Commanders are cautioned of the necessity to anticipate requirements for an airlift operation and
arrange for timely delivery. The drogue parachute is ready available from GM Rigging Unit (Parachute
Maintenance), and Area Resupply Co., all Airborne units and all Air Force Cargo Wings. The drogue
parachutes will not be issued with the Supplementary Set SC5420-97-CL-E51.
(1) Perform Steps (1) through (16) of high bank launch para. 2-16 in area specified by unit
commander.
NOTE
For interior bays, lifting sling legs must be equal in length with sling eye centered over bay. For ramp bays,
sling legs connected to lower lock drive end of bay will be longer than those connected to approach ramp
end, however sling eye must still be centered over bay.
(2) Connect sling (1) to lift/anchor points (2) on bay with hook face outward.
