FLIGHT INSTRUMENTS
ALTIMETER
The Altimeter displays 1,000 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 current altitude is displayed in the black pointer.
The Altimeter also displays a reference to the height above the ground; refer to Radar Altimeter discussion
later in this section for more information.
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
Selected Altitude.
Setting the Selected Altitude:
Turn the
ALT SEL
Knob to set the Selected Altitude in 100-ft increments (increments reduce to 10 feet for
approach) up to the aircraft’s service ceiling. 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 for the Selected Altitude.
If desired, press the
ALT SEL
Knob to synchronize the selected altitude to the displayed altitude to the nearest
10 ft.
