FLIGHT INSTRUMENTS
ALTIMETER
The Altimeter displays barometric altitude values in
feet on a rolling number gauge using a moving tape. The
Altimeter displays the following information:
• Altitude values
• Altitude reference bug
• Altitude trend vector
• Altitude reference box
• Barometric setting box
• Metric display

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 Reference Bug
The Altitude Reference bug is displayed at the reference
altitude or the edge of the tape (whichever is closer to the
current altitude) to provide increased altitude awareness.
To set the altitude reference bug:
1. 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
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 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 of the Altitude Reference box. The Altitude Ref
-
erence box is not part of the autopilot altitude preselect
system and is used to aide the pilot in altitude control.
Barometric Setting Box
The Barometric Setting box displays the barometric
pressure in inches of mercury (in Hg) or hectopascals
(hPa).
To select barometric pressure:
1. Turn the large BAR
O knob to select the
desired setting.
