Abstract
This paper discusses user requirements for Defence Research Establishment Valcartier's Eye-Save Laser-Based Obstacle Warning System (ELBOWS). An attitude survey on warning systems was administered to two Canadian Forces (CF) helicopter squadrons. Pilots and flight engineers were surveyed on current warning in CF helicopters and preferred characteristics of an obstacle warning system. A task analysis of portions of a Search and Rescue (SAR) mission was completed. The data in existing contractor reports was supplemented by interviews with subject matter expert. Information gathered included: initiating conditions, information requirements, cognitive and decisional elements and subject workload ratings. The results from the survey and task analysis have suggested several areas for further research. It is recommended that the three most common warning style suggestions from the attitude survey, i.e. voice directions; visual alert and directions; and audio alert, be tested for effectiveness in an experiment.
