Thursday, August 20th, 2009. Hand signals.
August passes as I immerse both in sea water and in an energetic activity of research for the wilderness emergency qualification. It seems to be expected for rescuers to be conversant with helicopter standard procedures in rescue evacuations, both in hot and cold loadings. Some of the precautions are fairly reasonable as being well away from the tail rotor and never, ever to direct a beam of light towards the crew while in night operations as in the chance that the pilots might be wearing night vision goggles, would effectively render them functionally blind which would bring about a whole new rescue scenario, which I regard as a spectacular way to flunk the Wemsi assessment.
Of course, I have grown a predilection for every bit about the hand signals both for the pilots and the winch operator. However, the vocabulary is actually quite scarce. There is ample room I believe, to pick up ideas from the standardized signals for close engagement operations. Besides, some paddlers rival and at times, excess the way this people dress.
Just the clarity of the combat hand signals for ordinal numbers deserve to be learned.
More to the point, ground-to-air signals are the same that a deployed rescue swimmer uses to communicate with the helicopter. To acknowledge the signals, the hoist operator should give a thumbs up or the pilot flash the rotating beacon. The signs made from a ground rescue party are as follows:
Deploy medical kit: Arms above head, wrist crossed
Situation okay: Thumbs up
Lower rescue cable with rescue device attached: Arm extended over head, fist clenched
Lower rescue cable without rescue device attached: Climbing rope motion with hands
Helicopter move in/out: Wave in/out with both hands
Cease operations: Slashing motion across throat
Deploy litter: Hands cupped, then arms outstretched
Personnel secured, raise cable: Vigorously shake hoist cable or thumbs up; vigorously up motion with arm
Team recall: Circle arm over head with fingers skyward
