Abstract
A system and method for generating lateral guidance image data and presenting information representative of the image data is disclosed. A system is disclosed for determining lateral guidance information based upon the elevation of terrain cells and a level of terrain threat associated with the elevation. A left or right turn angle, or both could be formed between a projected flight path and a vector extending to a tangent point of a terrain boundary to the left and right, respectively. The degree of angle could be determined for each, and lateral guidance image data based upon the boundary location of a level of terrain threat with respect to the projected flight path determined. A lateral processor provides an alert signal associated with the generation of the lateral guidance information and provide such signal to a crew visual and aural alerting system.
