Effect of a Monocular Helmet-Mounted Display on Aircrew Health: A Cohort Study of Apache AH Mk 1 Pilots Four-Year Review

摘要

This is the second biennial interim report for the study titled The Effect of a Monocular Helmet-Mounted Display on Aircrew Health: A Cohort Study of Apache AH Mk 1 Pilots. The principal aim of this occupational health study is to determine if the use of the monocular Integrated Helmet and Display Sighting System (IHADSS) helmet-mounted display (HMD) in the British Army's Apache AH Mk 1 attack helicopter has any long-term effect on visual performance. Additional information concerning other unique problems of the Apache AH Mk 1 aircrew is elicited as a secondary objective. This study is a collaborative effort between the British Army and the U.S. Army and is conducted under the auspices of The Technical Cooperative Program (TTCP), Subgroup U, Technical Panel 7 (Human Factors in the Aviation Environment). The current report presents the longitudinal data analysis for the approximate 5- year period January 2000 to December 2004. Visual performance data are examined for within- and between-subject differences for seven exposed (AH Mk 1) and 23 control subjects with a minimum of 3 years of measured data.
