FLIGHT INSTRUMENTS
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.
Setting the Selected Altitude:
Turn the
ALT
Knob to set the Selected Altitude in 100-ft increments (increments reduce to 10 feet for approach)
up to the aircraft’s service ceiling.
If set, 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 2-10). Note that the altitude tape does not change scale.
Displaying altitude in meters:
1)
Select the
PFD
Softkey to display the second-level softkeys.
2)
Select the
ALT
UNIT
Softkey.
3)
Select the
METERS
Softkey to turn on metric altitude readouts.
4)
Select 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.
