The Speed Deviation Pointer is displayed in yellow
when the cross-side FMS is the selected navigational
source. The pointer and scale will be removed from
the display.
k. Inclinometer Indicator. The inclinometer is
a separate element mounted under each display. The
inclinometer is a weighted ball in a liquid filled curved
glass tube to provide assistance in making coordinated
maneuvers. Aircraft slip/skid movement is shown by
the movement of the ball.
l. Marker Beacons. The inner, middle, or outer
marker beacon annunciation is displayed on the center
left of the display when set by the marker beacon
receiver. The marker beacon annunciator will be
removed from the display when the marker beacon
signal is no longer available from the marker beacon
receiver. The marker beacon annunciator consist of
an O in yellow for the outer marker, M in cyan for the
middle marker, and I in white for the inner marker.
m. Free Format Line. The free format line is
used to display system faults only.
n. Comparator Warning Annunciation. Each
display compares pitch attitude, heading, glideslope
deviation, localizer deviation, and radio altitude to the
cross-side (X-side) display. If the comparison exceeds
a threshold, the appropriate annunciation appears at
the top of the EADI.
o. Primary Flight Display Format. The
Primary Flight Display mode consists of an ADI
positioned on top of an HSI with a 360 compass rose.
Refer to Figure 3B-7.
(1) The rising runway and lateral deviation
pointer is removed from the ADI.
(2) Approximately 30 of the pitch scale is
visible.
(3) The Lubber Line is a solid white triangle
pointer and heading is not digitally displayed.
(4) Approximately 200 of the compass rose
is displayed. The bottom half of the compass rose is
clipped from view.
