A three-part study was conducted to assess the visual status of AH-64 pilots. The first part consisted of an anonymous questionnaire returned by 58 Fort Rucker instructor pilots. More than 80 percent of the pilots registered at least one visual complaint (visual discomfort, headache, double vision, blurred vision, disorientation, or afterimages) associated with flying or after flying the Apache aircraft. many of their comments indicated that symptoms occurred during long flights and/or flying with poor quality or out-of-focus display symbology. In the second part of this study, a comprehensive visual functions test battery was completed on 10 volunteer, highly experienced AH-64 aviators. In the third part of this study, measurements were made on the flight line of the Helmet Mounted Display diopter focus settings made by Apache IPs and students. The diopter settings ranged from 0 to -5.25 with a mean of -2.28. The required positive accommodation by the eye to offset these negative focus settings is very likely a source of visual discomfort and headache during and after long flights. (EMK).

Visual Issues Survey of AH-64 Apache Aviators (Year 2000). available in PDF, EPUB and Kindle. A web-based survey was conducted investigating AH-64 Apache pilot experience with the Integrated Helmet Display Sighting System (IHADSS). A total of 216 respondents provided responses in the following areas: visual complaints, helmet fit, and acoustics. Data indicated that 92% of respondents reported at least one visual complaint either during or after IHADSS flight. Additional findings include: no association between eye preference and frequency of complaints, an increase in frequency of visual complaints from a previous 1990 study, and no correlation between frequency of visual complaints and age or experience.

The incorporation of technology into aviation has been exponential. Advancements in microelectronics, stealth technology, engine design, and electronic sensors and displays have converted simple aircraft into formidable flying machines. In this book, recognised experts in aviation helmet-mounted displays (HMDs) summarise 25 years of knowledge and experience in the area of HMD visual, acoustic, and biodynamic performance, and user interface issues such as sizing, fitting, and emergency egress.
