DISPLAYING OBSTACLE DATA
The Terrain Proximity Page displays obstacle data
with heights greater than 200 feet Above Ground Level
(AGL) located at their geographical position loca-
tion throughout the world. Obstacles are displayed
in three levels. The G1000 will adjust colors on the
Terrain Proximity Page automatically as the aircraft
altitude changes. The display color patterns are as
follows:
• SAFE
• CAUTION
• WARNING
GRAY-Safe
Obstacle data is displayed in gray when the
obstacle height (MSL) is greater than 1000 feet below
the current aircraft altitude.
YELLOW-Caution
Obstacle data is displayed in yellow when the
obstacle height is 100 feet below MSL the current
aircraft altitude to 1000 feet below the current aircraft
altitude.
RED-Critical
Obstacle data is displayed in red when the obstacle
height is at or above 100 feet Mean Sea Level (MSL)
below the current aircraft altitude.
