Htaws Symbols - Garmin GNC 530W Manual

HTAWS Symbols

The symbols and colors in the following figures and table are used to represent obstacles and potential impact points on the
HTAWS Page. Each color is associated with a height above terrain.
The zoom range of obstacles (on the TAWS and NAV pages) is controlled by the NAV map' s "Setup Map" menu option
in the "Terrain" group under the "Obstacles" option. Obstacles can be shown up to the maximum zoom range on the TAWS
page. However, obstacles are ALWAYS shown on the TAWS page at 10 NM and below.
NOTE: If an obstacle or terrain cell and the projected flight path of the aircraft intersect, the display automatically zooms in to
the closest potential point of impact on the HTAWS Page.
