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.
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
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
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.
Pitch Scale
Indicates amount of pitch
up/down. Graduated in 5°
increments within ±30° of the
horizon line and in 20°
increments from 40 ° to 80°.
