Antenna Location - GOODRICH Stormscope Series II Installation Manual

4. After completion of the self-test, verify that the WX-950 is in the weather mapping mode; 200 nmi,
360° view.
5. Verify that clockwise rotation of the OFF/BRT knob increases display brightness and counter-
clockwise rotation decreases brightness. The screen should be completely dark with the control fully
counter-clockwise. Adjust to a comfortable viewing level.
6. Verify operation of the pushbuttons:
a. Press softkey (A), i.e., MENU. This should cause the system menu to be displayed with " Weather
View" menu item highlighted.
b. Press softkey (B), i.e., 360° . The display should return to the weather mapping mode, 360°
Weather View at the 200 nmi range.
c. Press softkey (C), i.e., down-arrow. The weather view range should change to 100 nmi.
d. Press softkey (D), i.e, up-arrow. The weather view range should return to 200 nmi.
7. If correct results are obtained, the system is operating properly. Immediately report any problems to
our Customer Service Department at 1-800-453-0288 or 1-616-949-6600.

2.4 ANTENNA LOCATION

Because Stormscope® weather mapping systems detect electrical discharge activity, antenna placement
relative to other active electrical components is critical. The antenna must be placed at a location that is
free from excessive electrical interference. The ideal location varies from aircraft to aircraft. To ensure an
interference-free antenna location, every aircraft must be skimapped prior to installation of the
Stormscope® antenna. The skinmap must be done with the engines and all electrical systems operating.
Refer to the WX-SM Skinmapper Instruction Manual (P/N 78-8060-5874-5).
The Stormscope® requirement for an antenna ground plane and a noise free
environment complicates installation in aircraft with wood, fabric or
composite construction. Each aircraft needs to be analyzed individually for
the best antenna location. Before starting an installation in one of these
types of aircraft, contact Goodrich Avionics Systems Field Service
Engineering at (800) 453-0288 or (616) 949-6600.
