c c c c c c c c




Responsibilities of the Pathfinder Unit - answer-- Provide advice and aid to thec c c c c c c c c c c c


csupported, aviation, and receiving units c c c c


- Provide expertise in the planning and execution of both PZ and HLZ operations
c c c c c c c c c c c c c

c c c c c c c c c


- Provide ground guidance and air traffic control during the sling load
c c c c c c c c c c c

c c c c c c c c c c




Types of Loads - answer-- High Density
c c c c c c


- Low Density
c c


- Aerodynamic
c




Unique Characteristic of High Density Loads - answer-Offers best stability
c c c c c c c c c


(ex. HMMWV)
c




Unique Characteristic of Low Density Loads - answer-Offers least stability
c c c c c c c c c


(ex. A22 Cargo Bag)
c c c




Unique Characteristic of Aerodynamic Loads - answer-Unstable until the load is
c c c c c c c c c c


cstreamlined, then it becomes stable c c c c


(ex. Downed Aircraft)
c c




Maximum External Load capabilities... - answer-will vary due to environmental
c c c c c c c c c


conditions and helicopter performance.
c c c c




What does ACL mean, what is it, and what is it based on? - answer-Allowable Cargo
c c c c c c c c c c c c c c c


Load - the maximum load capacity for a particular mission and determines what the
c c c c c c c c c c c c c c


helicopter can lift.
c c c

, Based on type of aircraft, age of airframe, pilot experience, altitude above sea level,
c c c c c c c c c c c c c


temperature, humidity, and aviation unit's SOP.
c c c c c c




APEX Requirements for UH-1 Iroquois - answer-A nylon point of attachment, like 3 ft
c c c c c c c c c c c c c


apex ring or basket hitch, must be used to attach load to aircraft. In addition, 11k cargo
c c c c c c c c c c c c c c c c c


hook reach pendant or a polyester round sling can be used as the point of attachment to
c c c c c c c c c c c c c c c c c


the A/C to a UH-1 series aircraft.
c c c c c c c




UH-1N/Y Cargo Hook Rated Capacity - answer-5,000 lbs
c c c c c c c




APEX Requirements of UH-60 Blackhawk - answer-When using 10k apex, aluminum
c c c c c c c c c c


apex spacer MUST be used. This will center apex on cargo hook and prevent apex from
c c c c c c c c c c c c c c c c


lifting the keeper during oscillation of the load, which would result in load being
c c c c c c c c c c c c c c


jettisoned from cargo hook.
c c c c


When using 25k apex, spacer MUST BE REMOVED. If 25k apex spacer used, air crew
c c c c c c c c c c c c c c


cannot jettison the load if required and cargo hook must be manually operated by the
c c c c c c c c c c c c c c c


crew chief or ground crew on LZ.
c c c c c c c


*NEVER* use nylon point of attachment such as 3 ft apex ring because it will bind on the
c c c c c c c c c c c c c c c c c


load beam of the argo hook and prevent the crew from releasing the load in an
c c c c c c c c c c c c c c c c


emergency situation.
c c




UH-60 Hook System Rated Capacity - answer-- A Model: 8,000 LBS
c c c c c c c c c c


- L Model: 9,000 LBS
c c c c


- M Model: 9,000 LBS
c c c c




APEX Requirements for CH-47 Chinook - answer-Requires no special apex in
c c c c c c c c c c


preparation and may accept all configurations. (ex. 10k apex with and w/o spacer, 25k
c c c c c c c c c c c c c c


apex with or w/o spacer, nylon multi-point configuration, etc.)
c c c c c c c c c


*DO NOT* attach single point loads to CH-47 D/F if there is nylon point of attachment to
c c c c c c c c c c c c c c c c


A/C
c




CH-47 D/F Cargo hook Locations and Rated Capacity - answer-- Center Cargo Hook:
c c c c c c c c c c c c


c26,000 lbs c


- CH-47 D/F Fore and Aft Cargo Hooks:
c c c c c c c


c1. Each: 17,000 lbs
c c c


c2. Combined: 25,000 lbs
c c c


c3. Fore and Aft Cargo Hooks are 13 ft apart
c c c c c c c c c




APEX Requirements for CH-53E Super Stalion - answer-Dual-point suspension system,
c c c c c c c c c


uses a forward and aft cargo hook, located 10 ft apart and must be used for dual-point
c c c c c c c c c c c c c c c c c


loads (A/C maximum lift capacity for this is 32,000 lbs with a max of 60% of sling load on
c c c c c c c c c c c c c c c c c c c


either forward or aft hook). A pendant is designed to be used with the dual-point system
c c c c c c c c c c c c c c c c


to provide more clearance between helicopter and hookup team.
c c c c c c c c c


Aircrew can open forward or aft cargo hook electrically or manually. Manual release
c c c c c c c c c c c c


lever is on left side of cargo hook. In emergency, ground crew open hook by moving
c c c c c c c c c c c c c c c c


manual release lever up.
