Altitude Reference Bug
The Altitude Reference Bug is displayed at the refer-
ence altitude to provide increased altitude awareness. If
the reference altitude is above or below the displayed alti-
tude scale, the Altitude Reference Bug is displayed at the
top or bottom edge of the tape, respectively.
To set the altitude reference bug:
Turn the ALT knobs to set the altitude reference

bug. The small ALT knob sets the hundreds and
the large ALT knob sets the thousands. This
altitude also appears in the altitude reference
box above the altimeter.
Altitude Trend Vector
This 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 the altitude
will be in 6 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 avail-
able due to a system failure.

Altitude Reference Box

The Altitude Reference box displays the reference alti-
tude in feet. The metric value, when selected, is displayed
on top the Altitude Reference box.

Barometric Setting Box

The Barometric Setting box displays the baromet-
ric pressure in inches of mercury (IN.) or hectopascals
(hPa).
To select barometric pressure:
Turn the large BARO knob to select the
