This video from Air Rescue Systems (ARS) shows its recent training with the Utah Department of Public Safety using a hoist extension line system — a new technique to extend the usable length of hoist cable on smaller aircraft. The Utah team, which flies Airbus H125/AS350 helicopters, can now get 200 feet down into slot canyons for rescue operations, something that wasn’t possible with just the 165 feet of hoist cable installed on the aircraft. Moreover, unlike typical hoist cables, the 50 feet of Dyneema hoist cable extension line can make direct rock contact without damage, ARS says. At the end of the video, the team extracts the rescuer and performs a “backing-reversal” dynamic hoist to move away from the cliff area.
