AN EXPLORATORY FLIGHT INVESTIGATION OF HELICOPER SLING-LOAD PLACEMENTS USING A CLOSED-CIRCUIT TELEVISION AS A PILOT AID

摘要

Helicopter sling-load operations have been limited during pick-up and delivery of external cargo by the lack of precision achieved by the combination of pilot, helicopter, and sling load. Use of a closed-circuit television as a pilot aid during sling-load delivery and placement was documented along with additional cases representing procedures currently employed by military and commercial operators. Although an increase in pilot workload was noted when the television system was used, the results indicated a comparable level of performance for each test case.
