The present invention is a method for providing optimum multi-map overlay in a flight deck navigation display of an aircraft. The method includes outputting absolute terrain data to the navigation display for display by the navigation display. The method further includes receiving a threshold elevation input, the threshold elevation input including a threshold elevation. The method further includes receiving relative terrain data. The method further includes, when the aircraft is located below the threshold elevation, overlaying the relative terrain data onto the absolute terrain data based on the received threshold elevation input. Further, the absolute terrain data and the relative terrain data are concurrently displayed by the navigation display, the displayed relative terrain data being overlaid onto the displayed absolute terrain data.

1. A method for providing optimum multi-map overlay in a system of an aircraft, comprising: outputting absolute terrain data via a first module of the system to a navigation display of the system for display by the navigation display;receiving a threshold elevation input, the threshold elevation input including a threshold elevation, said threshold elevation being a threshold distance above terrain for the aircraft;when the aircraft is located below the threshold elevation, outputting relative terrain data via a second module of the system, the second module being communicatively coupled with the first module; andwhen the aircraft is located below the threshold elevation, overlaying the relative terrain data onto the absolute terrain data based on the received threshold elevation input, the absolute terrain data and the relative terrain data being concurrently displayed by the navigation display when the aircraft is located below the threshold elevation, the displayed relative terrain data being overlaid onto the displayed absolute terrain data,wherein the overlaid relative terrain data is removed and only the absolute terrain data is displayed via the navigation display when the aircraft has changed its current location from being located below the threshold elevation to being located above the threshold elevation,wherein the first module scans the relative terrain data which is output by the second module and determines positions of hazards based on the relative terrain data. 2. A method as claimed in claim 1, wherein the displayed relative terrain data is displayed as relative terrain shading. 3. A method as claimed in claim 2, further comprising: scanning the received relative terrain data for determining locations of cautions and warnings, the cautions and warnings indicating positions of hazards. 4. A method as claimed in claim 3, further comprising: overlaying the cautions and the warnings onto the absolute terrain data based on the determined locations. 5. A method as claimed in claim 4, wherein the absolute terrain data and the cautions and warnings are concurrently displayed by the navigation display, the displayed cautions and warnings being overlaid onto the displayed absolute terrain data. 6. A method as claimed in claim 5, wherein the cautions and the warnings are displayed at a first resolution and the absolute terrain data is displayed at a second resolution, the second resolution being higher than the first resolution. 7. A non-transitory computer-readable medium having computer-executable instructions for performing a method for providing optimum multi-map overlay in a system of an aircraft, said method comprising: outputting absolute terrain data via a first module of the system to a navigation display of the system for display by the navigation display;receiving a threshold elevation input, the threshold elevation input including a threshold elevation, said threshold elevation being a threshold distance above terrain for the aircraft;when the aircraft is located below the threshold elevation, outputting relative terrain data via a second module of the system, the second module being communicatively coupled with the first module; andwhen the aircraft is located below the threshold elevation, overlaying the relative terrain data onto the absolute terrain data based on the received threshold elevation input, the absolute terrain data and the relative terrain data being concurrently displayed by the navigation display when the aircraft is located below the threshold elevation, the displayed relative terrain data being overlaid onto the displayed absolute terrain data,wherein the overlaid relative terrain data is removed and only the absolute terrain data is displayed via the navigation display when the aircraft has changed its current location from being located below the threshold elevation to being located above the threshold elevation,wherein the first module scans the relative terrain data which is output by the second module and determines positions of hazards based on the relative terrain data. 8. A non-transitory computer-readable medium having computer-executable instructions for performing a method for providing optimum multi-map overlay in a flight deck navigation display of an aircraft as claimed in claim 7, wherein the displayed relative terrain data is displayed as relative terrain shading. 9. A non-transitory computer-readable medium having computer-executable instructions for performing a method for providing optimum multi-map overlay in a flight deck navigation display of an aircraft as claimed in claim 8, said method further comprising: scanning the received relative terrain data for determining locations of cautions and warnings, the cautions and warnings indicating positions of hazards. 10. A non-transitory computer-readable medium having computer-executable instructions for performing a method for providing optimum multi-map overlay in a flight deck navigation display of an aircraft as claimed in claim 9, said method further comprising: overlaying the cautions and the warnings onto the absolute terrain data based on the determined locations. 11. A non-transitory computer-readable medium having computer-executable instructions for performing a method for providing optimum multi-map overlay in a flight deck navigation display of an aircraft as claimed in claim 10, wherein the absolute terrain data and the cautions and warnings are concurrently displayed by the navigation display, the displayed cautions and warnings being overlaid onto the displayed absolute terrain data. 12. A non-transitory computer-readable medium having computer-executable instructions for performing a method for providing optimum multi-map overlay in a flight deck navigation display of an aircraft as claimed in claim 11, wherein the cautions and the warnings are displayed at a first resolution and the absolute terrain data is displayed at a second resolution, the second resolution being higher than the first resolution. 13. A system for providing optimum multi-map overlay for an aircraft, comprising: a first module, the first module being configured for outputting absolute terrain data;a second module, the second module configured for being communicatively coupled with the first module, the second module further configured for outputting relative terrain data and a threshold elevation, said threshold elevation being a threshold distance above terrain for the aircraft; anda navigation display, the navigation display configured for being communicatively coupled with the first module, the navigation display further configured for displaying the absolute terrain data, the navigation display being further configured for displaying relative terrain data when the aircraft is located below the threshold elevation, the relative terrain data being overlaid onto the displayed absolute terrain data by the first module, wherein the overlaid relative terrain data is removed and only the absolute terrain data is displayed via the navigation display when the aircraft has changed its current location from being located below the threshold elevation to being located above the threshold elevation,wherein the first module is further configured for scanning the output relative terrain data of the second module and determining the positions of hazards based on the relative terrain data. 14. A system as claimed in claim 13, wherein the display is further configured for displaying cautions and warnings based on the output of the relative terrain data from the second module, the cautions and the warnings being overlaid onto the displayed absolute terrain data by the first module, the cautions and warnings indicating positions of hazards. 15. A system as claimed in claim 13, wherein the displayed relative terrain data is displayed as relative terrain shading.
