Supported unit, Supporting unit, Receiving unit What is the supported unit and their 4 responsibilities? The unit whose equipment will be moved. They are responsible for: -Advanced coordination with the supporting unit no later than 24 hours prior to the mission -Actual rigging of the loads -Furnishing slings, straps, clevises, and any other sling load equipment required for the move -Assuring that the loads are properly rigged and do not exceed the Allowable Cargo Load (ACL) of the aircraft. What is the supporting unit and their 4 responsibilities? The aviation unit that will fly the load(s). They are responsible for: -Ensure that the loads fall within the transporting aircrafts ACL -Provides assistance in the recovery and return of sling-load equipment. -Advises the supported unit on load limitation -Advise the supported and receiving units on the suitability of selected LZs/PZs Establish coordination with the supported and receiving units. What is the receiving unit and their 3 responsibilities? Normally an internal element of the supported unit, but not always. They're responsible for: -Selecting, preparing, and controlling the landing site to include communications -Receiving and de-rigging the load -Ensure proper supervision of the de-rigging Provide the return of lifting equipment and or personal. What is a Pathfinder and what are their 5 responsibilities? Is a Pathfinder considered a necessary unit in Sling Load Operations? Subject matter experts in all aspects of sling load operations; the Pathfinder can either be its own entity or broken up into the other three units. They are responsible for: - Provide advice and aid to the supported, aviation, and receiving units -Provide expertise in the planning and execution of both PZ and HLZ operations -Supervise the rigging and inspection of all the loads. -Provide ground guidance and air traffic control during the sling load. -Ensure that the loads fall under the transporting aircraft's ACL The Pathfinder is not considered a unit for sling load operations What are the three types of loads and what is their stability? High density: offers the best stability Low density: offers the least stability Aerodynamic: unstable until streamlined; then becomes stable What is the maximum external load (MEL)? The aircrafts maximum load capacity that will vary based on environmental conditions and helicopter performance. What is the allowable cargo load (ACL) and what is it based on? the maximum load capacity for a particular mission and determines how much the aircraft can lift. Based on TAPAHAT. What is TAPAHAT? The type of aircraft Age of airframe Pilot experience Altitude above sea level Humidity Aviation unit's SOP Temperature What is the Cargo Hook Rated Capacity of the UH-1 variants? UH-1N and UH-1Y: 5,000 lbs What are the CAN and CAN NOTs of the UH-1 apex requirements? CAN: Nylon, Polyester roundsling, 11k Cargo Hook Reach Pendant CAN NOT: Metal, 25k Cargo Hook Reach Pendant What are the rated capacities of the UH-60 variants cargo hooks? A Model: 8,000 lbs L and M Models: 9,000 lbs What are the CAN and CAN NOTs of the of the UH-60 apex requirements? CAN: 10k apex w/ spacer installed, 25k apex w/o spacer installed, polyester roundsling, 11k CHRP CAN NOT: Nylon, 25k CHRP, 10k apex w/o spacer, 25k apex w spacer Why must a spacer be used on a 10k apex when using a UH-60? The spacer centers the apex on the cargo hook and prevents the apex from lifting the keeper during oscillation of the load, which would result in the load being jettisoned from the cargo hook Why can the UH-60 not take a 25k apex with spacer or nylon POA? The load won't be able to be jettisoned from the A/C cargo hook in case of emergency. They will have to be removed manually by the ground crew. What is the rated capacity of the center cargo hook, the fore and aft cargo hooks, and both the fore and aft cargo hooks combined for the CH-47 (both variants)? Center: 26000 lbs Fore and aft: 17000 lbs fore and aft combined: 25000 lbs What is the CAN and CAN NOTs of the CH-47 apex requirments? CAN: 10k and 25k apex w/ spacer, 10k and 25k w/o spacer, any nylon MULTI point configuration, 11k and 25k CHRPs, field expedient attachments to include the large suspension clevises. CAN NOT: Single point nylon POA What is the length of the CH-47 rotor? 60 ft What is the length of the CH-47 body? 51 ft In what manner should loads of different weights to multiple cargo hooks on the CH-47 be attached, if all going to the same destination? Heaviest load on the center hook Next heaviest (middle wight) load on the forward cargo hook Lightest load on the aft (rear) cargo hook When attaching loads that are being flown to different destination to multiple cargo hooks on the CH-47, how should they be attached? First to be delivered and lightest load on the forward cargo hook Second to be delivered and next heaviest on the aft cargo hook last to be delivered and the heaviest load on the center hook. What is the carrying capacity for the center cargo hook and the fore and aft cargo hooks combined for the CH-53E Super Stallion (both variants)? Center: 36000 lbs Fore and aft combined: 32000 lbs What is the max and min carrying capacity of the CH-53E Super Stallion? Max: 32000 lbs Min: 6000 lbs (can not jettison lighter loads) What are the CAN and CAN NOTs of the apex requirements for the CH-53E Super Stallion? CAN: 10k and 25k apex w/ spacer, 10k and 25k apex w/o spacer, any nylon MULTI point configuration, 11k and 25k CHRP, field expedient attachments to include the large suspension clevises CAN NOT: Single point nylon POA What is the length of the CH-53E Super Stallion rotor? 72 ft 3 in What is the length of the CH-53E Super Stallion body? 67 ft What is the distance between the fore and aft cargo hooks of the CH-53E Super Stallion? 10 ft What is the allowable weight distribution between the fore and aft cargo hooks of the CH-53E Super Stallion? 50/50 optimal 60/40 max. 60% being on either the fore OR aft hook How can the aircrew open the cargo hooks on the CH-53E? Electrically or manually. There is a manual release lever is located on the left side of the cargo hook. When attaching dual point loads to the CH-53E Super Stallion and not using a CHRP, how many static discharge men are required? Each hook being utilized must have its own static discharge man. What is the rated capacity for the cargo hook on the CH-46A/D/E Sea knight? 10000 lbs [Show Less]
