Chinook CH-47/Mission

SECTION 4. MISSION

1 CARGO HOOK SYSTEM

1.1 General

Three cargo hooks (forward, mid and aft) are mounted on the belly of the aircraft for attaching external cargo. Each hook can be used to carry a separate load, in tandem configuration with the front and aft hooks, or in a tripple hook configuration.

All hooks have normal and emergency release modes. Normal release is performed with hydraulic pressure from the utility hydraulic system and is activated by a release switch on the cyclic, or on the hoist hud. Emergency list on all hooks is performed electrically off of the hot battery bus.
