ALTIMETER
The Altimeter displays 600 feet of barometric altitude values at a time on a rolling number gauge using a
moving tape. Numeric labels and major tick marks are shown at intervals of 100 feet. Minor tick marks are at
intervals of 20 feet. The current altitude is displayed in the black pointer.
The Selected Altitude is displayed above the Altimeter in the box indicated by a selection bug symbol. A bug
corresponding to this altitude is shown on the tape; if the Selected Altitude exceeds the range shown on the
tape, the bug appears at the corresponding edge of the tape. The metric value, when selected, is displayed in a
separate box above the Selected Altitude.
Setting the Selected Altitude:
Turn the ALT Knob to set the Selected Altitude (large knob for 1000-ft increments, small for 100-ft
increments).
The minimum descent altitude/decision height (MDA/DH) value is also available for the Selected Altitude.

Selected and current altitudes can also be displayed in meters (readouts displayed above the normal readouts
in feet; Figure 2-11). Note that the altitude tape does not change scale.
Displaying altitude in meters:
1) Press the PFD Softkey to display the second-level softkeys.
2) Press the ALT UNIT Softkey.
3) Press the METERS Softkey to turn on metric altitude readouts (see Figure 2-11).
4) Press the BACK Softkey to return to the top-level softkeys.
A magenta Altitude Trend Vector extends up or down the left of the altitude tape, the end resting at the
approximate altitude to be reached in 6 seconds at the current vertical speed. The trend vector is not shown if
altitude remains constant or if data needed for calculation is not available due to a system failure.
