Procedure – Upper Over Fin Fairing – INSTALLED –
SUBTASK AMM-34-40-50-071-A-701-002
A.
Test Set-Up
NOTE: With the WX-PA antenna placed on top of the fin fairing cap (over the
Stormscope antenna), the Stormscope unit will plot data on the GPS 400W
display at a farther range than the range selected on the WX-PA. This is because
of the greater offset distance between the WX-PA antenna and the Stormscope
antenna. For example, in the following steps, a test range of 30 NM is selected
and the resulting displayed strikes occur at approximately 50 NM.
IMPORTANT!
If for any reason the WX-PA tester produces “double image” lightning
strikes on the Garmin 400W display, where the programmed strike pattern appears and
additional strikes appear on a reciprocal bearing (180° away), then the Upper Over Fin
Fairing must be removed and the “Procedure (Upper Over Fin Fairing NOT Installed)”
must be performed. Refer to
SUBTASK AMM-34-40-50-071-A-701-001
.
NOTE: Operator should be familiar with the WX-PA Portable Analyzer Kit.
(1) Make sure that all aircraft power is off.
(2) Attach the WX-PA test set’s antenna on top of the vertical tail fin fairing cap (over the
Stormscope antenna).
(a) Position the WX-PA antenna on the fin fairing cap 5.75 inches aft of the top
center fastener.
•
If necessary, use tape to secure WX-PA antenna to the fin fairing cap; see
(b) Be sure to align the WX-PA antenna’s arrow pointing forward, centered on the
top of the fairing.
(3) Route the WX-PA antenna cable away from the aircraft.
(a) Connect the antenna cable to the WX-PA test box.
(b) DO NOT POWER UP THE TEST SET.
(4) On the IPL set the SYS BATT and START BATT switches to the ON (up) position
and BUS TIE to AUTO (up) position.
