RAH-66 Comanche Health Hazard and Performance Issues for the Helmet Integrated Display and Sighting System.

Abstract : The helmet integrated and display sighting system (HIDSS) is a combination of a protective helmet, helmet mounted display (HMD), and helmet mounted sighting system. It is planned for use in the Army's next generation reconnaissance/attack helicopter, the RAH-66 Comanche. In 1986 and 1988, USAARL developed and published guidelines for addressing potential health hazard issues with the HIDSS. The most recent version of these guidelines was USAARL LR 88-4-21-1O, 'Revision for the health hazard issues in the MIDSS.' This paper is a further revision of these issues. In addition to recommendations provided for performance in the areas of biodynamics, optics/vision, and acoustics, a number of safety and training issues are discussed.
