11.5 Displaying Direction Indicators
Direction Indicators let you know the approximate pointing direction of the dome in
relation to an established point called “North”.
When enabled, the Direction Indicators appear along the top edge of the display. In
addition, a tilt elevation indicator also appears along the left edge of the display.
The value of the tilt elevation indicator is relative to the “virtual horizon” of 0° tilt. By
default, the display of Direction Indicators is disabled.

In this example, the current pointing position is 60° from North. The tilt elevation is 12°
above the virtual horizon. Panning to the left points the dome towards the Northeast.
Panning to the right points the dome towards the East. If you tilt below the virtual
horizon, the negative values will be displayed along the left edge (for example, -25).
The elevation values range from +25° to -90°.
If you pan to a position that corresponds to a well-known navigational heading, the label
corresponding to the heading appears in the center position. Fig. 44 illustrates the
navigational headings and their corresponding degrees from North.
