If the flight director data

becomes invalid, a red “FD”
enclosed in a red box will be dis-
played at the right center of the dis-
play and the command bars will be
removed.

Autopilot engagement is annun-

ciated by a green “AP”. A green “YD”
is annunciated to indicate the yaw
axis is engaged.

If the autopilot has been on and

then is disengaged, a red “AP”
annunciation will momentarily flash in
the upper left hand corner of the dis-
play and then be removed. The yaw
damper, if engaged, will provide a
flashing red “YD” annunciation upon
disengagement.

Command Reference Data —The
following autopilot command refer-
ence data will be displayed in green
on the electronic attitude indicator
when interfaced with the KFC 500:

• Vertical Speed

± 3,500

fpm in 100 fpm increments.

• Altitude

0 to 65,536

FT in 10 FT increments.

• Indicated Airspeed

Vertical Scale

— When the selected

primary NAV sensor is ILS or MLS, a
vertical deviation scale will appear on
the right side of the EADI display. This
scale provides a reference for the
vertical deviation pointer and the
center of the glide path. If the
selected sensor is ILS or MLS, a
“GS” annunciation appears. The
vertical deviation scale is in view
only when the selected course is
within 105 degrees of the aircraft
heading.

Expanded Lateral Deviation Scale
– Located at the bottom center of
the EADI, the expanded lateral
deviation scale provides a
reference for ILS or MLS lateral
deviation. The expanded scale
represents 1/2 full scale deviation
as displayed on the EHSI. When
the selected course and aircraft
heading differ by more than 105
degrees, the left/right directional
display is reversed and a BC
annunciation is displayed left of the
center diamond to alert the pilot that
back course information is being
displayed.
