Terrain augmented 3d flight path display for flight management systems

Abstract

The computation and data load for producing a flight plan and terrain display for a flight management system is reduced through the use of intelligent level of detail control which computes and displays flight plan areas and related terrain with a high level of detail. The outer terrain details, i.e., those further removed from the flight path, are processed and displayed in a manner that shows all significant terrain features, e.g., peaks, towers, and the like, but with much less detail so as to significantly reduce the overall computational load for producing such 3D flight path displays in real time. This ensures that all-important information relative to the flight path is correctly processed and displayed while secondary information is shown with important features to provide broad awareness of areas surrounding the intended flight path.
