[. . . ] 988-0154-512 Terrain Awareness Upgrade For AirMap 2000 This Terrain Awareness upgrade allows your AirMap 2000 to show the ground in color shaded relief format, and uses different colors to highlight terrain with potentially hazardous altitudes. Terrain awareness is represented by light green, yellow and red highlights. [. . . ] Color Code As you fly, the AirMap notes your current altitude and the height of the terrain below you. 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. The top window (Map Window) shows the relief map overlaid with Jeppesen data and terrain awareness color shading. The bottom window (Profile Window) shows your altitude relative to a 2D cross-section of the terrain under and ahead of you. Map Window In the Map Window, the cross-hatched line extending from the nose of the aircraft symbol represents your projected track. The area under this projected track is shown in the Profile Window below. As you move the cursor, the projected track line will swing around, leading the cursor.
