vice versa. Once the baro setting
display is visible the rotary knobs
may be used to manually adjust the
baro setting if automatic baro correc-
tion is not available.
12. ALTITUDE ARM (ARM) BUT-
TON - When pushed will toggle alti-
tude arming on or off. When ALT
ARM is annunciated, the autopilot
will capture the altitude alerter dis-
played altitude (provided the aircraft
is climbing or descending in VS to
the displayed altitude). When the
autopilot is engaged, ALT arming is
automatic upon altitude alerter alti-
tude selection via the rotary knobs.
Note that the alerter functions are
independent of the arming process
thus providing full time alerting, even
when the autopilot is disengaged.
13. ALTITUDE ALERTER/VERTI-
CAL SPEED/BARO SETTING DIS-
PLAY - Normally displays the alti-
tude alerter selected altitude. If the
UP or DN button is pushed while in
VS hold, the display changes to the
command reference for the VS
mode in FPM for 3 seconds. If the
BARO button is pushed, the display
changes to the autopilot baro setting
in either IN HG or HPA for 3 sec-
onds.
NOTE: This display may be dashed
for up to 3 minutes on start up if a
blind encoder is installed which
requires a warm up period.
14. ALTITUDE ALERT (ALERT)
ANNUNCIATION - The ALERT
annunciate is illuminated 1000 ft.
prior to the selected altitude, extin-
guishes 200 ft. prior to the selected
altitude and illuminates momentarily
when the selected altitude is
reached. Once the selected altitude
is reached a flashing ALERT illumi-
nation signifies that the 200 ft. “safe
band” has been exceeded and will
remain illuminated until 1000 ft. from
the selected altitude. Associated with
the visual alerting is an aural alert (5
short tones) which occurs 1000 feet
from the selected altitude upon
approaching the altitude and 200
feet from the selected altitude on
leaving the altitude.
15. PITCH TRIM (PT) ANNUNCIA-
TION - A flashing PT with arrows
indicates the direction of required
pitch trim. A solid PT without an
arrow head is an indication of a pitch
trim fault. During manual electric trim
operation (autopilot disengaged),
detection of a stuck MET switch will
be indicated by a solid PT. When the
fault is corrected, the annunciation
will extinguish.
16. PITCH MODE DISPLAY -
Displays the active and armed pitch
modes (VS, ALT, ARM, ALT and
GS).
17. ROLL MODE DISPLAY -
Displays the active and armed roll
modes (ROL, HDG, NAV ARM,
NAV, APR ARM, APR, REV ARM,
REV, GS ARM). Also displayed will
be flashing AP annunciation (5 sec-
onds) at each autopilot disconnect
accompanied by an aural tone (for 2
seconds).
18. AUTOPILOT ENGAGED (AP)
ANNUNCIATION - Illuminates when-
ever the autopilot is engaged.
Flashes during pilot initiated or auto-
matic disengagement. Only applica-
ble for software versions 03/01 or
later.
