Altitude Tape
2.3.2.3. Altitude Tape, Altitude Alerter, and Vertical Speed
Altitude is indicated by a moving altitude tape against a xed position altitude pointer
(Figure 2-2, No. 21, 24), shown on the right-hand side of the Attitude Display
(Figure 2-31). A numerical rolling drum readout indicating altitude values to the closest
20 feet is provided adjacent to the xed pointer. When climbing or descending, a
magenta Altitude Trend Vector displays above or below the altitude pointer, indicating
the altitude that will be reached in six seconds if the current rate of climb or descent is
maintained.
Minor tick marks are provided on the tape at 20-foot intervals, and major tick marks are
provided at 100-foot intervals. The thousand and ten-thousand digits are larger than
other digits on the tape. Negative altitudes are indicated by a “-“ sign preceding the
numerical altitude value in the drum.
The current altimeter barometric pressure setting is shown just below the Altitude tape
in the Data Bar (Figure 2-2, No. 39), and can be adjusted by pressing the BARO Hot Key
and rotating the Right Knob.
The Altitude Tape also includes a built-in Altitude Alerter, which consists of an
Altitude Bug on the Altitude Tape (Figure 2-2, No. 26), a Selected Altitude Field
(Figure 2-2, No. 22), a visual Altitude alert (Figure 2-2, No. 23), and an optional audio
alert. For more information on using the Altitude Alerter, see Chapter 3 and Chapter 4.
A Vertical Speed Indicator (VSI) is shown as a tape on the Navigation Display (Figure
2-48 and Figure 2-2, No. 57) to the right of the HSI in 360 Compass mode. A numerical
vertical rate is shown in the upper right-hand corner of the Navigation Display during
climbs and descents (Figure 2-2, No. 56). The VSI tape is not shown in ARC Compass
mode, but the numerical value display is shown in both 360 and ARC Compass modes.
