Synthetic vision versus the pilot´s existing view

This paper is intended to serve as a “human factors reality-check” reference that can be used by synthetic vision system designers to help determine when they may be going down a road that is not leading to a useful end product. FAA regulations and SAE Aerospace Recommended Practices that relate to the pilot´s eye view are discussed as appropriate to ensure the ultimate goal of certifying the system is not lost. The role of the pilot´s view of the world through the windscreen in existing aircraft is explored with respect to synthetic vision and to a lesser extent to enhanced vision. The primary flight display format and the presentation of specific data are discussed from a human factors point of view. Potential design issues that deserve up front definition are presented to serve as guideposts to explore prior to any detail design
