6.4 WX-500 Lightning Sensor Strike Test
With a WX-500 lightning sensor installed and set up, the Maintenance Mode page will have a Lightning
Strike Test key which enables you to test the lightning sensor.
➤ To perform the Lightning Strike Test:
1. On the Maintenance Mode page, press Lightning Strike Test.
2. The Map page opens and displays a single strike on the 15 mile range and 45 degrees relative
bearing. If the strike does not appear in that position, there may be a heading source, wiring, or
MFD setup problem.
3. Rotate the aircraft to the 4 cardinal compass points and perform the strike test. The strike should
display at 45 degrees relative bearing at each heading point
6.5 Traffic Test
After completing all configuration procedures, confirm that the MFD is configured for the correct Traffic
sensor.
6.6 ORBCOMM Satellite Reception (EX500 Only)
Two-Way satellite networks transmit very low power signals that the EX500 must receive. If the
antenna is not properly installed or if there is excessive electromagnetic interference (such as a nearby
radio transmitter, ground power cart, or inadequately grounded avionics), the system will not achieve
successful reception.
➤ To assess system performance.
1. Bring the aircraft to an area with the clearest view of the sky to the horizon.
2. Monitor the Datalink Info table (Figure 19), for a few minutes (up to 5) under each of the following
conditions:
■ Other Avionics OFF
■ Avionics ON
■ Engines at idle
■ Engines at takeoff power.
3. With a satellite in view, the signal strength and quality should peak above the following values:
Maintenance Mode > System Info > Datalink >
Two-Way Datalink Info
Trip Page > Two-Way Datalink Status
Signal strength > -118 dBm
(-130 is lowest, -100 is highest)
Signal Strength > 4, (scale of 1-10)
Estimated SNR (EbNo) > 10 dB Signal Quality > 4, (scale of 1-10)
Segment errors = Less than 10% Message Quality = 10, (scale of 1-10)
