The terrain data includes high resolution maps for North and South America and lower resolution maps for the rest of the world. [. . . ] The relief map shows areas with different risk levels in different colors, according to the following perimeters: · Red highlight: indicates terrain that is at your current altitude or higher. · Yellow highlight: indicates terrain 500 feet below your current altitude. · Green highlight: indicates terrain 1, 000 feet below your current altitude. · When flying over the ocean, the surface shading in the Profile Window reverts to a pattern of small Xs, indicating no risk of flying into elevated terrain. All map screens will show the terrain relief shading except for the Navigation Panel and the Aviation Map option. On those screens, the terrain awareness color highlight does appear. 2 Navigation Airspace Page This upgrade adds the Navigation Airspace Page to the unit's major operating modes.

As you move the cursor, the projected track line will swing around, leading the cursor. The 2D display changes according to the selected terrain. [. . . ] The terrain appears in cross-section at the bottom of the window. The terrain is color coded to indicate the relative elevation below you.
