Mode and Data
Display
This display normally
shows operating modes and
associated numerical data. It is
also used to display setup mode
screens and the setting of
associated numerical data.
When displaying operating
modes, the left side shows
lateral data and the right side
shows vertical data. (See figure
below) The upper left display
labeled
TRK shows the
electronic DG slaved to GPS
track. When the GPS track is
not available
TRK will be
replaced by BANK , which
means the autopilot now uses
its internal gyros for bank angle
control. The lower left display
labeled
SEL shows the selected
direction of flight when in the
standard track mode. When in
the gyro mode, the lower left
shows the current selected bank
angle. The upper right display
shows altitude or selected
altitude, and the lower right
display shows either selected
vertical speed or selected
airspeed.
The vertical space between
the left and right hand display
area is used to show pitch trim.
This display consists of four
horizontal bars spaced
vertically as the rungs on a
ladder, and are made to move
up or down when the aircraft is
in need of being trimmed.
In the upper left where
direction is shown, a flashing
indicator is present in the center
left of the display. When there
is no GPS signal present the
display will show
NO GPS .
When there is no GPS position
information the indicator will
be a flashing period, and the
display will show
NO FIX .
Once GPS position data
becomes valid the indicator will
be a flashing asterisk, and the
display will show
GPS OK . If
GPS flight plan information is
being received over the serial
channel or if GPS steering
information is being received, a
flashing plus sign will indicate
the presence of a useable
steering (GPSS mode) or
waypoint to waypoint (GPS
NAV mode) signal.
A cursor in the form of an
underline is shown beneath the
SEL numerals. This is used to
indicate that an underlined
number will be set by rotation
of the encoder knob.
