A simple profile view of the Fight Management System (FMS) vertical flight plan can be provided using current Cathode Ray Tube (CRT) Electronic Horizontal Situation Indicator (EHSI) with a software program in the FMS when the map is in the plan mode. A 3-D graphical representation of the FMS vertical profile can be provided by introducing a multipurpose higher resolution flat panel display and through integration with the Terrain Awareness and Warning System (TAWS). Ultimately an enhanced configuration is preferred that integrates the 3-D and horizontal views with high-resolution terrain on the primary flight displays.
