15. Press MENU/ENTER to start the test.
16. Observe the MFD to ensure the proper positioning of the strikes, based on range and
azimuth settings on the WX-PA. Change the cardinal bearings and verify correct test
strikes. Verify the strikes are within 10 degrees of the selected azimuth and plot at 60NM
(1/2 120 NM).
17. Verify after 20 seconds of operation the strike counter reads 580 +/-40.
18. After testing for all ranges and bearings indicated, press 2ND then MENU/ENTER to
return to the main menu.
19. Select Circular Pattern mode on the WX-PA mode menu and press MENU/ENTER.
20. Select bottom mount antenna configuration on the WX-PA keyboard ("A" key).
The MFD should be set at 100 NM (or next highest available range) on the 360-
degree weather screen and in strike mode.
21. Use the F1 and F2 keys to select 120 NM range and press MENU/ENTER to start the
test. Verify the WX-500 plots discharge points at approximately 60 NM.
22. Observe the MFD to ensure the proper positioning of the test strikes. Verify the strikes
are within 10 degrees of the 30-degree azimuth increment and within 12 NM of 60 NM,
23. When complete, set WX-PA for 55 NM, set the MFD for 50 NM (or the next highest
available range) and repeat test.
24. On the MFD, verify the sensor plots points just outside of 25 NM and the strikes are
within 10 degrees of the 30-degree azimuth and within 5 NM of 27.5 NM.
25. Repeat above setting the MFD for 25 NM (or the next highest available range) and the
WX-PA for 15 NM.
26. On the MFD, verify the positioning of test strikes are within 10 degrees of azimuth and
within 2 NM of 7.5 NM.
27. Restart the G1000 in configuration mode by opening the PFD and MFD circuit breakers.
While holding the ENT keys on the PFDs and MFD, restore power by closing the PFDs
and MFD circuit breakers.
28. Select the OTHER page group on the MFD. The Map - Stormscope Map page is
shown by default.
If no other service is to be performed, continue to the return-to-service checks in Section 9.
