Purpose Advantages And Limitations Of Sling Loads

Question 1

Helicopters will move cargo by external sling load when :

Answer 1

Cargo compartment cannot hold the load

Load exceeds the helicopters internal load limitations

Ground crew must load or unload the cargo at one time

Landing zone conditions prevent the AC from touching down

Question 2

Advantages of sling loads are :

Answer 2

Allows rapid movement of heavy oversized or emergency equipment

Rapid relocation of supplies and equipment

Ability to bypass surface obstacles

Use of multiple flight routes and landing sites to enhance sustainability and security of ground units

Est. Of multiple landing sites to support the manuevering unit requirements

Greater movement flexibility for the ground commander to accomplish the tactical mission

Question 3

Limitations of sling loads are :

Answer 3

Weight of load is restricted to the AC operating capabilities

Load instability during flight may restrict AC airspeed ir manuevering capabilities

Adverse weather and low vis. May limit sling load ops

Atmospheric conditions (HAT and winds) affect AC lift capabilities

Limited number of AC are available for sling load missions

Landing site surface conditions may restrict AC ops, loose debris dust and snow are safety hazards that also limit pilot vis.

Landing site size must be increased during darkness or during low vis. To allow the pilot more room to maneuver

Question 4

Question 6

Allowable cargo load for external loads on a CH47 D

Answer 6

Fore and aft hooks each 17000lbs
Center hook 26000 lbs
Fore and aft hooks together fuel point tandem 25000lbs

Question 7

When will the ground crew manually release the cargo hook

Answer 7

Only when the hook malfunctions and will not release by other means

Question 8

How can the cargo hook be released on the UH60

Answer 8

Pilot or crew chief can release the hook electronically, manual release lever is on the right side of the hook

Question 9

How can the CH47 release the cargo hook

Answer 9

Pilot or crew chief can release all hooks electronically

Crew can release all hooks manually from inside

Fore and aft hooks have manual release knobs

Center hook has no release lever for the ground crew
