or X POINTR to determine the desired flight
director information.
Altimeter
Moving Tape Display Box
White numerals and tick marks on a transparent
rolling-tape display box indicate altitudes
currently above and below the current altitude.
Each minor tick mark indicates 20 feet,
and each major tick mark (with a number) indicates
100 feet.
Altitude Pointer
The current altitude (indicated in feet above
mean sea level) appears as a rolling numeric
display (white numbers on black) in the center
of the altitude display box (Figure 16-15).
This display has a pointer, which always points
at the center of the altitude tape.
Trend Vector
On the inside left edge of the tape, a magenta
trend vector indicates predicted altitude in 6
seconds at the current rate of altitude change.
Selected Altitude Bug and Box
A box at the top of the altitude display indicates
the preselected altitude. A corresponding
notched cyan bug appears on the right edge of
the altitude display at the selected altitude, or
at the end of the display if the selected altitude
is off scale. The reference altitude is selected
with the ALT SEL knob on the AFCS controller.
Reference Altitude Alerting
When the aircraft is more than 1,000 feet above
or below the reference altitude, the digits in
the selected altitude box are cyan on black

(see Figure 16-15). When the aircraft is at the
reference altitude (±1,000 feet), the colors reverse
(black digits on cyan). When approaching
within 1,000 feet of the reference altitude,
the digits and their background flash (alternate
colors) continuously for 5 seconds. When departing
the reference altitude by ±200 feet, the
digits flash amber on black for 5 seconds
(Figure 16-16).
Barometric Setting
A box at the bottom of the altitude tape indicates
the current altimeter setting in inches of mercury
(or hectoPascals, if set to metric values)
(Figure 16-17). To adjust the setting, rotate the
BARO knob on the right side of each PFD bezel.
The BARO settings on the pilot and copilot
PFDs can be synchronized through the PFD
setup menu window.
NOTE
If pilot and copilot PFD barometric
settings differ by more than .02
inches (of mercury), the barometric
setting boxes on both displays appear
with amber digits. The baro settings
for both PFDs can be synchronized.
Barometric Altitude Minimums and
Alerting
For altitude awareness, a barometric minimum
descent altitude (MDA, or decision height) can
be set (Figure 16-18). When active, the MDA
is displayed in a box labeled “BARO MIN” to
the lower left of the altimeter and on the altitude
tape with a bug (once the altitude is within
range of the tape). This altitude can be adjusted
in the BARO MIN field in the timer/references
window from 0 to 16,000 feet (in 10-foot increments
when using the small FMS knob). The
MDA is reset any time the power is cycled.
Metric/Standard Units of Measure
After pressing the PFD softkey, an ALT UNIT
softkey appears. It allows the display of the
digital altitude and barometric pressure indications
in metric values: altitudes in meters
(MT) and barometric pressure in hectoPascals
(hPA). The altitudes appear in boxes above
the normal digital displays, which continue to
display in feet. The moving-tape display continues
to display in feet. The barometric pressure
box at the bottom of the display changes
to hPA indications.
