7.18 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.

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.

7.18.2 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.

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.

The Map page may be configured by the pilot to not show any

obstacles or wires at any zoom scale.
