The National Research Council of Canada, in conjunction with the Canadian Department of National Defence, is investigating the use of helmet-mounted displays as an aid in improving pilot situational awareness in all-weather search and rescue helicopter operations. For over 30 years, the NRC Bell 205 Airborne Simulator has been an integral part of valuable research programs. Equipped with a full authority fly-by-wire control systems, the Bell 205 has variable stability characteristics, which makes the airborne simulator the ideal platform for the integrated flight testing of helmet-mounted displays in a simulated operational environment. This paper describes the test facility in detail, including a description of the airborne simulator, the fiber-optic helmet-mounted display hardware, the camera system, the head tracking system, and the sensor platform. In addition, the paper provides a complete description of the symbology overlaid on the camera image that was developed for use with the helmet mounted display. The paper concludes with the description of a planned preliminary handling-qualities investigation into the effects of using helmet-mounted displays on the pilot's workload and performance while performing standard manoeuvres.
