Glossary
AGL Indication (Rad Alt, GPS Alt, Baro Alt)
– Display of altitude above
the ground, with designation of the altitude source as R (radio altitude),
G (GPS WAAS geodetic altitude less local ground elevation), or B
(barometric altitude less local ground elevation).
Air Data and Groundspeed
– Display of density altitude, outside air
temperature, ISA temperature deviation, true airspeed, and
groundspeed.
Airspeed Information
– Display of airspeed is the indicated airspeed tape
and airspeed readout with associated data. The airspeed function
includes color-coded caution bands for minimum and maximum speeds
based on V-speeds set in the EFIS limits.
Altitude Information
– Display of altitude information is the altitude tape
and altitude readout.
Approach Mode Signal Output
– Conventional autopilot approach mode
signals are course error output, the left/right deviation signal (localizer
output) and the up/down deviation signal (glideslope output). Signals
are based on the selected ILS source.
Attitude Information
– Display of attitude information includes pitch and
roll. The bank angle scale may be set to auto-declutter by the pilot when
the bank angle is less than 2.8°. The pitch ladder is limited to ±10° from
the flight path marker or aircraft waterline, whichever is greater. The
unusual attitude display appears when the aircraft pitch exceeds ± 30°
or bank angle exceeds 65° (fixed wing) or 50° (Rotorcraft).
Autoset
– Automatically selects features or settings.
Azimuth
– Angle between the north vector and the perpendicular
projection of the star down onto the horizon. Usually measured in
degrees (°).
Barometric Altimetry
– Measurement of altitude based on the atmosphere
(pressure and temperature).
Barometric Correction
– Display and altitude correction for local
barometric pressure.
Bezel
– Faceplate of the IDU comprised of pushbuttons along the
pushbuttons along the sides and rotary encoders along the bottom.
Chroma
– Colorfulness relative to the brightness.
Conformally
– Angle-preserving. Example: Traffic appears conformally on
the PFD.
