Airspeed Tape –
Indicated airspeed with a display range from 20 knots to 300 knots. Each
minor graduation represents 2 knots and each 10 knot major graduation is labeled. Color
bands are aircraft type specific.
Red Band:
Never exceed speed, V

, up to top of the
airspeed tape.
Yellow Band:

NO
, up to never exceed
speed, V

•
Aircraft Reference Symbol –
Current aircraft pitch angle is represented by the apex of the
yellow delta-shaped reference against the pitch ladder.
ADI Symbology
•
Flight Director Steering Command Bars –
Displays the accuracy of the pilot or autopilot
tracking the autopilot commands. The pilot or autopilot is to steer the airplane toward the
command bars until the delta shaped reference is tucked into the steering command bars.
•
Autopilot Annunciation Window –
The Autopilot annunciation area repeats the System
Fifty Five X faceplate annunciations in the pilot’s primary field of view.
•
Pitch Ladder –
The pitch ladder has graduations every 2½° within the range of ±20° and
graduations every 5° from +20° to +50° and -20° to -30°. The 10° graduations of the pitch
ladder have bar ends that point toward the horizon line. Large chevrons visible at excessive
pitch angles, point toward the horizon when above +50° and below -30°. ±90° is represented
by small circles.
•
Bank Angle Indicator –
Composed of an inverted white triangle and an upright white
triangular Roll Pointer. The upright white triangle points to the current bank angle.
Graduations are at 0, 10, 20, 30, 45, and 60 degrees. (Note: the 0 and 45 degree marks are
inverted triangles.)
•
Skid/Slip Indicator –
The black trapezoid is centered under the roll pointer in coordinated
flight. Full-scale deflection is the width of the trapezoid.
•
Altitude Tape –
Displays pressure altitude (with barometric correction) with a display range
from -1,000 feet to 35,000 feet. Each minor graduation represents 20 feet and each 100-foot
graduation is labeled.
•
Altitude Window –
Displays current baro-corrected altitude.
•
Vertical Speed Indicator (VSI) –
The scale graduations between ±1,000 fpm, are every 100
fpm. Above scale limits, a digital readout of the current vertical speed is displayed on the
appropriate end of the VSI scale. The max displayed value of the digital readout is ±4,000
fpm.
•
Horizontal Deviation Indicator (HDI) –
Displayed when VLOC is selected as the NAV
source and the localizer signal is received. The source of the HDI data is displayed
immediately to the right of the HDI (e.g. LOC or ILS). If the signal is lost, the HDI is
replaced with a red-“
X
” and the source letters turn red. Once displayed, changing the NAV
source or changing the VOR/LOC frequency may remove the HDI.
•
Vertical Deviation Indicator (VDI) –
Displayed when VLOC is selected as NAV source
and the ILS glideslope signal is received. The source of the VDI data is displayed
immediately below the VDI (e.g. ILS). If the GS signal is lost, the VDI is replaced with a red
“
X
” and the letters ILS turn red. Once displayed, changing the NAV source or changing the
localizer frequency may remove the VDI.
