1. A terrain profile system comprising:

  • a data store that includes a non-transitory machine readable memory that stores map data corresponding to map software for displaying a map, digital terrain, and elevation data (DTED) associated with the geographic region of interest;

    a human-machine interface (HMI) that includes a route input system to receive user inputs to define a planned flight path of an aircraft between two points on a map associated with the map data and with defining flight characteristic data associated with the aircraft;

    a terrain profile controller that determines a terrain elevation and generates a terrain profile comprising a terrain signature that includes a topography of maximum elevation terrain features of the geographic region of interest with respect to an altitude of the aircraft within a path-width corridor along the planned flight path based on the user inputs defining the planned flight path, the DTED, and a planned altitude of the aircraft along the planned flight path based on the flight characteristic data;

    a sub-route generator that receives a user selected start line and end line on the terrain profile to generate a sub-terrain profile comprising a finer granular profile of the terrain profile for a portion of the planned flight path that is defined in a bounding window bounded by the start line and the end line on the terrain profile, wherein a start point and an end point defining a sub-route of the planned flight path, corresponding to the start line and end line, are generated on the map in response to the start line and end line selected on the terrain profile; and

    a display system that displays the terrain profile comprising the terrain signature, the planned altitude relative to the terrain signature, a real-time location of the aircraft superimposed on the planned altitude based on real-time location data associated with the aircraft, and the sub-terrain profile;

    wherein the HMI controls the aircraft in real-time according to the user inputs.
