cue to aircraft position relative to actual heading and
selected heading.

from the nose of the aircraft symbol to the map lubber line as
a magenta, dashed line. The selected IRS
source provides this
data (Figure 212).
Heading Display - The displayed compass rose consists of an
expanded 120-degree arc that is divided into 5-degree

displayed
in white.
The display is augmented with a white
digital readout of actual heading above the compass lubber-line
(Figure 212).
