Symbolic Aircraft and
Horizon Bar
Airplane attitude is indicated
by the position of the fixed
aircraft symbol with respect
to the movable horizon bar.
Bank Scale and Pointer
Airplane bank angle is indicated by the
position of the white pointer on the bank
scale. Scale indices represent 0, 10, 20,
30, 45 and 60 degree bank angles.
Rate of Turn Indicator
Needle indicates turn rate and
direction. Outer marks indicate
standard rate turn of three
degrees per second.
Glideslope Pointer and Scale
Pointer represents glideslope
beam and moves up or down
the glideslope deviation scale
to indicate vertical displacement
of the aircraft from the glideslope
center. In view only when
localizer is tuned and reliable
glideslope is present.
Runway and Runway Extension Indicator
Indicates lateral displacement of the aircraft from the localizer. In
view only when a localizer is tuned. The runway indicator will rise
vertically to indicate radio altitude from 200 feet to touchdown,
each mark on the rising runway represents 100 feet.
Command Bars
The rotation indicates the roll correction which the aircraft must make
to maintain a selected heading or course, and the placement on the
pitch ladder indicates the pitch correction the aircraft must make to
maintain altitude, pitch, or to track the glideslope. Bars appear when
a valid flight director mode is commanded by an external control panel.
Speed Command Circle

Circle moves up or down
the scale to indicate
deviation from selected
airspeed.
