TERRAIN PROFILE SYSTEM
First Claim
1. A terrain profile system comprising:
- a data store that includes a non-transitory machine readable memory that stores map data, digital terrain, and elevation data (DTED) associated with the geographic region of interest;
a user interface that includes a route input system that facilitate user inputs associated with defining 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 to thereby define a terrain signature that includes a topography of maximum elevation terrain features of the geographic region of interest with respect to an altitude of that aircraft within a path-width corridor along the planned flight path based on the DTED and a planned altitude of the aircraft along the planned flight path based on the flight characteristic data; and
a display system that displays a terrain profile comprising the terrain signature, the planned altitude relative to the terrain signature, and a real-time location of the aircraft superimposed on the planned altitude based on real-time location data associated with the aircraft.

Abstract
One example includes a terrain profile system. A data store stores map data of a geographic region of interest and DTED. A route input system facilitates user inputs associated with defining a planned flight path of an aircraft between two points on a map associated with the map data and with defining flight characteristic data of the aircraft. A terrain profile controller defines a terrain signature associated with a topography of terrain features of the geographic region of interest along the planned flight path based on the DTED and a planned altitude of the aircraft along the planned flight path based on the flight characteristic data. A display system displays a terrain profile comprising the terrain signature, the planned altitude relative to the terrain signature, and a real-time location of the aircraft superimposed on the planned altitude based on real-time location data associated with the aircraft.

11. A method for generating a terrain profile for an aircraft, the method comprising:
-
storing map data and digital terrain and elevation data (DTED) associated with a geographic region of interest in a memory; displaying a map associated with the map data on a display system associated with a human-machine interface (HMI); facilitating user inputs associated with defining a non-linear planned flight path of an aircraft between two points on the map and with defining flight characteristic data associated with the aircraft; generating a terrain signature that includes an aggregate topography of terrain features of the geographic region of interest within a path-width corridor along the non-linear planned flight path based on the DTED; generating a planned altitude of the aircraft along the non-linear planned flight path based on the flight characteristic data; displaying the terrain profile comprising the terrain signature, the planned altitude relative to the terrain signature, and a real-time location of the aircraft superimposed on the planned altitude based on real-time location data associated with the aircraft on the display system associated with the HMI. - View Dependent Claims (12, 13, 14, 15, 16)

17. A terrain profile system comprising:
-
a data store that includes a memory to store map data associated with a geographic region of interest, and to store digital terrain and elevation data (DTED) associated with the geographic region of interest; a terrain profile controller that defines a terrain signature associated with a topography of terrain features of the geographic region of interest along a non-linear planned flight path of an aircraft based on the DTED and that defines a planned altitude of the aircraft along the non-linear planned flight path based on flight characteristic data; and a human-machine interface (HMI) comprising; a route input system that facilitates user inputs associated with defining the non-linear planned flight path of the aircraft between two points on a map associated with the map data and with defining the flight characteristic data associated with the aircraft; and a display system that displays the map, the real-time location of the aircraft superimposed on the non-linear planned flight path on the map based on real-time location data associated with the aircraft, a 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 the real-time location data associated with the aircraft, and a sub-terrain profile defined between two points on the terrain profile, the sub-terrain profile being displayed in a similar size as the terrain profile to thereby provide finer granularity of the terrain profile. - View Dependent Claims (18, 19, 20)
