Terrain Symbols
The symbols shown below are used to represent
obstacles and potential impact points on the Terrain
Page. Note that obstacle symbols are shown on display

The Garmin TERRAIN system uses yellow (caution)
and red (warning) to depict terrain information relative
to aircraft altitude. Each color is associated with an
alert severity level. Terrain graphics and visual annun-
ciations also use these color assignments.
