Abstract
The CH-146 Griffon Combat Support Helicopter operates on Air Weapons Ranges in close proximity to fast-moving fighter aircraft. The Canadian Armed Forces has undertaken to improve the conspicuity of the Griffon by considering alternative lighting and paint schemes. DRDC Toronto was requested to assist in this endeavour and to contract a review of the relevant conspicuity literature. This report documents the review and provides a summarising checklist of factors that should be considered when attempting to enhance conspicuity. A number of conclusions are drawn and some recommendations are made. These recommendations refer to positioning and flash-rate of lights, painting the aircraft light colours on the top and dark colours on the underside, painting discontinuous stripes on the main rotor blades, and the continuing use of procedural range control.
