Rescue hoist is
hydraulically powered by the back-up hydraulic pump, operating at power supplied by #2 DC Primary bus, emergency power from #1 DC Primary bus (via CBs for both)
Rescue hoist components include
hoist assembly, cockpit/cabin controls, relay CBs, and necessary electrical wiring
Speed
Breeze-eastern: 0-215fpm
Lucas-western: 0-250fpm
The hoist has _____ ft of usable cable. The first and last ____ ft are _________.

20ft
bright orange
Rescue hoist control panels
- primary controls are the rescue hoist control panel and the AW pendant
- the hoist responds to the first control received
- there is one control panel in the cabin and one in the upper console for pilot control
Emergency release/hoist sheer controls
- one emergency release on pilot/copilot cyclics, and are capable the rescue cable
- OFF – any time this switch is OUT of the off position, power is provided to both cabin and cockpit switches
- ALL – enables cyclic EMER REL and cabin HOIST SHEAR switch
Pilot Hoist Control (speed)
- fixed at speed of 100fpm
- whenever hoist speed is >50fpm in either direction and there’s 10ft left from full up or 5ft left from full down, IT WILL AUTO SLOW DOWN TO 50 FPM
Hover Trim Control Panel
-it’s right above RESCUE HOIST control panel, controls hover position when crew hover is engaged
Hoist thumbwheel switch
- HOIST thumbwheel switch (on pendant) controls the hoist at variable speed up to max, spring loaded to neutral/stopped position
- also, has ICS trigger and cargo hook release switch
Rescue hoist backup control
- in the cabin
- emergency power switch and control up-down switch is fixed at 85 fpm
- speed limit switches are INOP when backup controls are in use
Rescue hoist cautions
- the rescue hoist cable must be kept clear of all parts of the aircraft and free from other external obstacles when operating the hoist. Cable abrasion during hoist operations can lead to cable failure. If cable contact or snagging occurs, suspend hoist operations and inspect the cable for damage in accordance with applicable procedures
- slack cable may entangle personnel or equipment and cause damage or injury if cable comes under tension
Cable shear
- In an emergency, you can cut the cable. It is powered by the DC ESNTL bus.
- CAD cable cutter can be triggered by 2 emergency release buttons (cyclic) or hoist shear switch (hover trim panel, cabin)
- switches are energized when airborne and RSQ HOIST PWR/ARMED switch is out of the OFF position
- with WOW, all jettison switches are INOP (not including fuel)
Cable Shear caution
-Pressing the cyclic EMER REL pushbutton with SONAR ARMING panel, CARGO HOOK CTRL armed, RSQ HOIST PWR/ARMED armed, and the RAST MASTER ON will fire the respective CADs
Rescue Hoist limits
600# suspended (300#/person)
or 200# of cargo (double check this #)
HSI/HVR/MAP Mode displays
HSI - shows your tacan/nav aid, fly to point
HVR - shows drift, box
MAP - if you are flying a flight plan
Wapoints
used for flight planning, don’t disappear when flown over. Selected from DAFIF or can be manually input by pilot
