Altitude Values
The 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.
Altitude Select Bug
The Altitude Select Bug is displayed at the Selected
Altitude or the edge of the tape (whichever is closer to
the current altitude) to provide increased altitude aware-
ness. This altitude also appears in the Selected Altitude
Box above the Altimeter.
To set the Selected Altitude bug:
Turn the ALT knobs to set the Selected Altitude
bug. The
small ALT
knob sets the hundreds and
the large ALT knob sets the thousands.
Altitude Trend Vector
The vertical, magenta line extends up or down the al-
titude scale located left of the numeric labels. The end
of the trend vector displays approximately what altitude
will be reached in six seconds if the current rate of vertical
speed is maintained. The trend vector is absent if altitude
remains constant or if any data needed to calculate it is not
available due to a system failure.
Selected Altitude Box
The Selected Altitude box is located above the Altim-
eter and displays, in feet, the altitude selected by turning
the
ALT knobs. The metric value, when selected, is dis-
played on top of the Selected Altitude box.
Barometric Setting Box
The Barometric Setting Box displays the barometric
pressure in inches of mercury (in Hg) or hectopascals
(hPa).
To select barometric pressure:
Turn the
large BARO
(outer) knob to select
the desired setting.
