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.
NOTE: If an obstacle and the projected flight path of
the aircraft intersect, the display automatically zooms in
to the closest potential point of impact on the TERRAIN
page.
