Model-Based Method for Terrain-Following Display Design.

摘要

A model-based method for terrain-following display design and evaluation is described. The basic approach centers on the use of a pilot/vehicle/display model based on the optimal control model (OCM), which combines general knowledge of human perception and performance, with specific knowledge of terrain-following aircraft and avionics capabilities. A real-time terrain-following simulation facility was developed, implemented, and exercised to provide an experimental basis for validating model-based display designs, and to serve as a tool for developing and testing displays. Two basic display configurations were studied: a nominal vertical situation display (VSD) along with several enhancements, and a pictorial guidance display (PGD). Model-based analysis of the real-time simulator data demonstrated the ability to closely match performance and frequency response trends across the range of display configurations studied, accounting for both general performance trends and fine-grained pilot dynamic response strategy in the measured data.
