Autopilot - For use with Autopilots that use both RS-232 and ARINC 429 data. The transmitted labels
are as follows:
001 Distance To Waypoint (BCD) 012 Ground Speed (BCD)
101 Selected Heading
114 Desired Track (True)
117G Vertical Deviation
147G Magnetic Variation
206 Indicated Airspeed
251 Distance To Waypoint
320 Magnetic Heading
371G Manufacturer ID
ARINC 429 Inputs:
Garmin GPS – Receives GPS labels from a 4XX/5XX series unit. A second selection is used to
determine if the GPS input is from NAV 1 or NAV 2.
Garmin VOR/ILS – Receives VOR/ILS labels from a 4XX/5XX series unit. A second selection is used
to determine if the GPS input is from NAV 1 or NAV 2.
7.4.9 GPS Configuration Page (multiple GDU installations only)
The GPS Configuration Page allows selecting the GPS source for each GDU. Each installed GDU can
select either the GPS antenna directly connected to that GDU, or 'No GPS Antenna Connected'. If 'No
GPS Antenna Connected' is selected, that GDU will use GPS data from the GDU that is connected to a
GPS Antenna. Only one GDU need be connected to a GPS Antenna, that GDU will "share" the GPS info
will all other GDUs. This page does not appear if only a single GDU (and no GSU 73) is installed.
Failure of a single GDU or GPS antenna (in a multi-display/multi-antenna installation)
would cause the system to use GPS information from the remaining functional GDU. If
no GPS data is available from any operating GDU, the remaining GDUs will use GPS
position data from an external GPS navigator (GNS 4XX/5XX). Accuracy will be
degraded when using an external GPS navigator.
1. In configuration mode, use the FMS Joystick to select the GPS Page.
2. Use the FMS Joystick to select the desired configurable item and make the desired change.
Then press the ENT Key or use the FMS Joystick to select the next item. Press the FMS
Joystick to move the cursor to the page selection menu when finished.
