Paper Abstract

A web-based study was conducted to determine the continuing presence and frequency of visual complaints reported by pilots using the monocular Integrated Helmet and Display Sighting System (IHADSS) helmet-mounted display (HMD) of the AH-64 Apache helicopter. A total of 216 pilots responded to the survey, which addressed areas of visual symptoms experienced during and/or after flight, helmet fit, and acoustics. Ninety-two percent of the pilots responding to the survey reported at least one visual symptom. The most frequently reported symptom for both during and after flight was visual discomfort. One out of four respondents reported having some difficulty in purposefully alternating between visual inputs to the two eyes. Approximately two-thirds of the pilots responding expressed reasonable satisfaction with their current helmet fit.
