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 (Figure 2-10). See the AFCS Section for more information about
Selected Altitude.

A magenta Altitude Trend Vector extends up or down the left of the altitude tape.  The end extends to 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.

 Turn the ALT SEL Knob to set the Selected Altitude in 100-ft increments.  When meters are displayed, Selected 
Altitude is adjusted in 50 meter increments.

If set, the Minimum Descent Altitude/Decision Height (MDA/DH) value is also available as a Selected Altitude 
setting.
