3-50 HAC Board Questions Flashcards
What is the actual name of the 3-50?
NAVY SEARCH AND RESCUE (SAR) MANUAL NTTP 3-50.1
What is Short-Hauling? Considerations?
A rescue method utilized for the extraction of a survivor on vertical/near-vertical terrain. It may also be used in cases where the hoist cable length is insufficient or the hoist is inoperative. It terminates at the predetermined landing zone.
The aircraft should not exceed 40 KIAS during short-hauling evolutions.
During SAR, how close can you get to a parachute?
If a parachute remains in the area of the survivor, maintain a minimum of 1 rotor diameter separation between parachute canopy and rotor downwash.
Would you use Direct Deployment on an Ejection Seat Survivor?
No, spinal immobilization is essential to ejection-egress aircrew. Aircrew who eject from aircraft must be presumed to have spinal injuries. Utilizing the rescue/MEDEVAC litter for recovery is highly recommended to help prevent a potentially life-threatening or permanent neurological injury. In conjunction with the use of the rescue/MEDEVAC litter, total spine immobilization including cervical collar, should be applied at the earliest convivence.
Would you use Direct Deployment on a Parachute Survivor?
No, direct deployment procedures shall not be used if survivor still has parachute attached, nor shall they be used in any parachute-disentanglement rescue scenario.
