If the altitude is displayed in feet, the Altimeter shows 600 feet of barometric altitude at a time, with numeric
labels and major tick marks displayed at intervals of 100 feet. Minor tick marks are at intervals of 20 feet.
If the altitude is displayed in meters, the Altimeter shows 180 meters of barometric altitude at a time, with
numeric labels and major tick market displayed at intervals of 50 meters. Minor tick marks are at intervals of
10 meters. The name of the selected units, 'FEET' or 'METERS', appears near the bottom of the altimeter.
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. See the AFCS Section for more information about
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 altitude alert value has been set, this altitude is also available for the Selected Altitude while turning
the ALT Knob.

The crew can choose to display overlays for the indicated altitude and Selected Altitude using complementary
display units without changing the scale of the Altimeter. For example, if the Altimeter is displaying feet, the
system can show a metric overlay for the indicated and selected altitudes without changing the scale or display
units of the Altimeter.
