Helicopters move cargo by external sling load when?
- The cargo compartment cannot hold the load
- The load exceeds the helicopters internal load limitation
- The ground crew must load or unload the cargo at once
- Landing zone conditions prevent the aircraft from touching down.
Sling load has how many advantages? What are they?
6.
- Allows rapid movement of heavy, oversized equipment, or emergency supplies directly to the user
- The rapid relocation of supplies and equipment

- The establishment of multiple landing sites to support the maneuvering unit requirements
- Greater movement flexibility for the ground commander to accomplish the tactical mission
Sling load operations have how many disadvantages? What are they?
7.
- Load weight is restricted to a/c capability
