Sling stuff Flashcards
Types of load
high density - stable, like a concrete block
low density - unstable, more likely to osscilate
aerodynamic - unstable until streamlined, then stable
Reasons to externally load
-Speed of attachment/detachment
-CG exceed if loaded internally,
-Cargo compartment too small
-PZ/LZ conditions dont permit touchdown
Two phases of takeoff with external load
-Lifting load to a hover
-Takeoff
How to fix fore-aft osscilation
shallow turn while reducing airspeed
How to fix left right osscilation
reduce airspeed
Warning for sling ops
Ensure personnel in cabin are secured with harness or in seat
Caution for sling ops
Static discharge wand will be used IAW 4-48
Standards for slings
-Verify 7382 and will remain within CG/weight
-Hook up and hover
-Ensure AC and load remains clear of obstacles
-Perform vertical ascent to load height 10ft +/- 5 feet
-Determine power sufficient without exceedences
-Maintain trim above 100ft AGL
-Maintain constant angle to ensure obstacle clearance, terminate over intended point of landing load height 10ft +/- 5ft
-Perform vertical descent with load to desired touchdown point +/- 5ft
PC responsibilities for slings
-Conduct crew brief, cover ops, emergency procedures, comm procedures
-Ensure 7382 completed
-Analyze TO direction based on wind, long axis, tactical situation
-Confirm power required PPC vs hover power check
Armed and safe when
Arm below 300ft AHO
Safe above 300ft AHO
Notes for slings
-Load must meet requirements 4-48
-Avoid overflight populated areas
-Familiar with hand signals and forced landing (everyone goes left)
-No movement of switches without verbal announcement
-Extenders
-Self hookups are authorized with stipulations
AOM Sling
-Submit notam
-All hook ups/releases will occur in NW side of NVD pad according to AOM
-Use fire lane
-Ground crew will remain in tree line when not operating
-Avoid populated overflight
-Leave blocks as far to the NE of north sod as is safe
-For long pattern, call inbound when turning at Marsh hall
