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 above the Selected Altitude.
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 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.
