Airplane Symbol 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, 60 and 90 degree bank angles.
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. The glideslope scale
and pointer are removed when
backcourse is active.
Command Bars
The vertical bar indicates the roll correction which the aircraft must
make to maintain a selected heading or course, and the horizontal
bar 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
and Scale
Circle moves up or down
the scale to indicate
deviation from selected
airspeed.
Sky
A small amount of sky will
always be shown if at the
top of the ADI, even if the
pitch exceeds viewable
limits of the sky.
Ground
A small amount of ground will always be shown, if at the top of
the ADI, even if the pitch exceeds viewable limits of the ground.
The eyebrow of ground will be obscured by the compass card at
the bottom.
Decision Height (DH)
Annunciation
Indicates when decision
height is reached.
Flight Director (FD)
Annunciation
Indicates when same flight
director computer is driving
command bars on both
Captain and FO sides.
Pitch Scale
Indicates amount of pitch
up/down. Graduated in 2.5
°
increments within
±
30
°
of the
horizon line and in 20
°
increments from 40
°
to 80
°
.
Decrab Symbol
Indicates rudder command
required to align aircraft with
runway. The decrab symbol
is only displayed on an
