3. For WX-500, set the following options:
■ Sensor – Select between the lightning sensor and a simulation program (WX-500 only). The
normal selection is the sensor name (“Avidyne TWX670” or “WX-500”). The WX-500
simulation setting is used in conjunction with the demo mode on the sensor to simulate
operations on the ground.
■ Operating Mode – The normal operating mode is weather. Demo is used to simulate lightning
operations. For the WX-500, Noise Monitor mode is used during noise mapping tests. See the
WX-500 installation manual for testing procedures.
■ Port – Set the MFD RS-232 port that is connected to the lightning sensor to match the aircraft
wiring.
■ Stab Type—Select the source of stabilization for use by the WX-500. Stabilization aids in
correctly positioning strikes when the aircraft is turning. The choices are:
◆ Synchro to WX500—a remote compass system that generates and transmits synchro
signals received by the WX-500. This heading data can also be used by the MFD to orient
the map.
◆ Stepper—a remote compass system that generates and transmits stepper signals
received by the WX-500. This heading data can also be used by the MFD to orient the
map. See the Map Heading Setup section.
◆ Use Map Heading/Track—The WX-500 uses orientation information supplied by the
MFD based on the Map Heading configuration, described in Section 5.11, “Map Heading
Source Setup” on page 64. The WX-500 receives heading or track data from the MFD via
RS232. Heading will be sent from the MFD only if GPS/FMS is the heading source via
ARINC 429.
The best method of stabilization is a heading source (synchro or stepper input to the WX-500
or Map Heading). The next best method is Track. The wiring and WX-500 jumpers must agree
with the setup on the MFD.
■ Enable Lightning Ahead Warning?—Enables display of the Lightning Ahead warning
message in the message bar when checked and disables it when not checked.
■ Antenna on Top?—Indicates that the sensor antenna is mounted on top of your aircraft when
checked and that it is mounted on the bottom of your aircraft when not checked.
