D. Heading Input Check
(1)
On the WX-PA, select “Continuous Out” on the MODE MENU, then press the MENU/
ENTR button once (so that WX-PA indicates “PAUSED” and not “RUNNING”).
(2) On the WX-PA, press the FLAPS/A button to select top mount antenna configuration
(if not already selected).
(3) On the WX-PA, select a cardinal bearing of 180° and a range of 30 NM.
• Use F1 and F2 buttons to adjust range and the F3 and F4 buttons to adjust
bearing.
(4) On the WX-PA, with “Continuous Out” still selected on the MODE MENU, then press
the MENU/ENTR button once so that WX-PA indication changes from “PAUSED” to
“RUNNING”.

NOTE: Strike RATE will recede then ramp up toward 600 ± 200 strikes per minute
again.
(6) Observe the GPS 400W Lightning display to ensure proper positioning of the test
strikes, based on range and bearing settings on the WX-PA.
(a)
Make sure that test strikes appearing on the GPS 400W Lightning display are
plotted at 180 ± 10° and approximately 50 NM.
(7) Make sure that the Strike RATE counter is strikes (600 ± 200 strikes per minute).
(8) With aircraft magnetic heading active, turn the aircraft 45 ± 5° to the right.
(9) Make sure that previously plotted discharge points move approximately 45°
counterclockwise (approximately 135° relative on the GPS 400W display).
