Abstract: A method and system for displaying three dimensional images of runways and terrain, as well as additional information, on one or more screens of an avionics display system is provided. The system merges elevation information for terrain points and elevation information for runway points by grouping runways together that are within a threshold distance of each other. For each group, a plane is calculated. The calculated plane is then projected onto all of the runways within the group. The plane may also be projected onto a subset of neighboring terrain points. The adjusted elevation created by the projection of the plane are then used in creating the images for display on the synthetic vision display. The result is that all of the runways within a group, along with their neighboring terrain, are displayed as being coplanar.
