The altimeter comprises an Altitude Bug, Numerical Altitude Value (drum), Altitude Tape,
Altitude Trend Vector, MINIMUMS annunciation, Selected Altitude Field value, Decision
Height Annunciation, Altitude Alerter and an aural tone (when congured) DH (Figure

The Altitude Tape range is from -1,600 to 51,000 feet. Major tick marks are provided
every 100 feet and minor tick marks every 20 feet. A barometric pressure adjustment
(BARO) is provided to the pilot to accurately display the aircraft’s altitude above mean
sea level.
The Numerical Altitude Value is shown in a rolling drum format in the center of the
Altimeter Tape, with numbers moving downward as the altitude increases and upward
as altitude decreases. The Numerical Altitude Value shows the altitude to the nearest
20 feet.
