Abstract

Helmet mounted displays (HMDs) provide increased capability to advanced aircraft systems but also add mass to the pilot's head. This mass potentially increases fatigue, degrades pilot scan patterns, and potentially increases chronic, as well as acute injury during accelerative loading. From a Human Systems Integration (HSI) perspective, HMD capabilities should be selected to maximize performance and minimize system total ownership costs (TOC). Unfortunately, a clear method does not exist for performing this HSI tradeoff analysis to include safety (acute neck injury), occupational health (chronic neck injury), human factors engineering (performance and fatigue), and survivability. This study utilized content analysis and data to develop a qualitative model of the impacts HMDs have on HSI. Further, recent research on neck injury risk criteria was applied to quantify the impacts of helmet mass on the ejection safety portion of the model. A methodology for the formulation of a quantitative model of parameters influencing the HSI impacts of HMDs was developed. This study illustrates the difficulty in formulating a rigorous optimization of HSI parameters for a HMD. If quantitative HSI assessments of realistic system performance and TOC are to be conducted, additional research will be required.
