Altimeter - Garmin G1000 NXi Pilot's Manual

ALTIMETER

The Altimeter displays 600 feet of barometric altitude values at a time on a moving tape rolling number gauge.
Numeric labels and major tick marks are shown at intervals of 100 feet. Minor tick marks are at intervals of 20
feet. The indicated altitude is displayed inside 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 upper or lower edge of the tape. When the metric value is selected it is displayed
in a separate box below the Selected Altitude.
A magenta Altitude Trend Vector extends up or down the left of the altitude tape, with the end resting at the
approximate altitude to be reached in six 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.
Setting the Selected Altitude:
Turn the ALT Knob to set the Selected Altitude. Turn the large knob for 1000-ft increments, small knob for 100-
ft increments. If set to Metric mode, the large knob adjusts the Selected Altitude in 500-meter increments; the
small knob adjusts the Selected Altitude in 50-meter increments..
If a Minimum Descent Altitude/Decision Height (MDA/DH) value has been set, this altitude is also available for
the Selected Altitude while turning the ALT Knob.

Altitudes can also be displayed in meters as an overlay. Note that the altitude tape does not change scale.
Displaying the metric altitude overlay:
1) Press the PFD Opt Softkey to display the second-level softkeys.
2) Press the ALT Units Softkey.
3) Press the Meters Softkey to turn on metric altitude readouts.
4) Press the Back Softkey twice to return to the top-level softkeys.
