Paper Abstract

The Integrated Helmet and Display Sighting System (IHADSS), employed in the U.S. Army's AH-64 Apache helicopter, is used to present pilotage and targeting imagery and symbology. Therefore, in addition to the standard comfort and protection requirements of a helmet system, the IHADSS must provide a stable optical alignment. Fielded in the early 1980's, the IHADSS is still the Army's only integrated helmet-mounted display (HMD). In an attempt to perform both the standard protective role of a helmet and to serve as a mounting platform for an optical sight, the IHADSS had to make certain design compromises that have resulted in some user satisfaction issues. A joint survey of U.S. and U.K. AH-64 aviators was conducted to identify and quantify these issues. Survey findings indicated that while a majority of aviators found the quality, comfort and satisfaction of fit to be acceptable, a significant proportion of aviators have encountered problems associated with obtaining proper helmet size, availability of replacement components, and substantial variation in fitting expertise. Results of this survey can assist in ongoing and future HMD helmet system designs.
