Altitude Tape And Vertical Speed - Aspen Avionics Evolution Backup Display EFD1000 Pilot's Manual

The pilot can set a target airspeed using the Bottom Knob (see Section 4.2.2.1.). The
target airspeed is shown on the Airspeed Tape as an Airspeed Bug with its setting
displayed numerically above the Airspeed Tape (Figure 4-10 and Figure 4-11).
The Airspeed Bug and numerical value are for visual reference only, to help the pilot
maintain a target airspeed; there is no alerting for deviations from the target.

2.3.2.3. Altitude Tape and Vertical Speed

Altitude is indicated by a moving altitude tape against a fixed position altitude pointer
(Figure 2-2, No. 21, 24), shown on the right-hand side of the Attitude Display
(Figure 2-19). A numerical rolling drum readout indicating altitude values to the closest
20 feet is provided adjacent to the fixed 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
Figure 2-19
other digits on the tape. Negative altitudes are indicated by a "-" sign preceding the
Altitude Tape
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 Top 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. 19). For more information
on using the Altitude Alerter, see Chapter 3 and Chapter 4.
