Depiction of Obstacles and Wires
7.18.1
Dedicated Terrain Page
The dedicated Terrain page will always depict point obstacles at zoom scales of
10 nm or less and depict wire obstacles at zoom scales of 5 nm or less. The
obstacle or wire overlay icon (see Figure 3) will be shown near the bottom of the
display when the obstacle or wire depiction is active based on the zoom scale.
NOTE
Only obstacles and wires within 2,000 feet vertically of the
aircraft will be drawn on the Terrain page. It is therefore
possible to have an obstacle or wire overlay icon displayed
with no obstacles or wires being depicted on the display.

Map Page
The Map page may be configured to depict point obstacles and wire obstacles at
various zoom scales by the pilot by using the Map page menu. The obstacle or
wire overlay icon (see Figure 4) will be shown near the bottom of the display
when the obstacle or wire overlay is active based on the current zoom scale and
setting selected by the pilot.
The settings chosen by the pilot on the Map page menu (including obstacle and
wire display ranges) are saved over a power cycle.
NOTE
Only obstacles and wires within 2,000 feet vertically of the
aircraft will be drawn on the Map page. It is therefore possible
to have an obstacle or wire overlay icon displayed with no
obstacles or wires being depicted on the display.
NOTE
The Map page may be configured by the pilot to not show any
obstacles or wires at any zoom scale.
