Page 9: Chapter 1, System Description
Chapter Chapter System Description System Description General Description ® The Stormscope Series II Weather Mapping System, model WX-1000 (figure 1-1) detects electrical discharges from thunderstorms up to 200 nautical miles away and displays the thunderstorm locations relative to your aircraft. The WX-1000 also provides checklists and timing functions. -
Page 10: Antenna
System Description The Stormscope system is a passive system so there is no transmitter and no harmful transmissions. The system operates as well on the ground as in the air, thereby giving the pilot important planning information before takeoff. The following paragraphs describe the three major compo- nents of the Stormscope system. -

System Description the discharge signals into range and bearing data then stores the data in memory. The Stormscope system then displays discharges as storm cells as described in the next paragraph. The Stormscope system plots a “+” symbol (discharge point) on the display when it detects associated discharges within the selected range and view. - Page 13 System Description • Display output to an EFIS display unit via ARINC 429 bus outputs, or to a radar indicator via the BFG Radar Graphics Computer model RGC250. The EFIS display unit or RGC250/ radar indicator can be in place of the standard WX-1000 display, or in addition to the WX- 1000 display.

Page 15: Chapter 2, Storm Mapping Principles
Chapter Chapter Storm Mapping Storm Mapping Principles Principles Anatomy of a Thunderstorm The Stormscope model WX-1000 is intended to help pilots avoid the dangers associated with thunderstorms (convective wind shear, lightning, icing, tornadoes, etc.). The Stormscope system locates thunderstorms by detecting the electrical discharges that thunderstorms always generate. - Page 16 Storm Mapping Principles b. The friction between the opposing air currents causes electrical charges in the area to separate. As positive (+) and negative (–) electrical charges are separated, they accumulate in masses of similar charges (positive charges near the top of the cloud and negative charges near the bottom).
-
Page 17: Stages Of A Thunderstorm
Storm Mapping Principles convective wind shear increases, the rate of electrical discharges increases at an increasing rate. This relationship means that if you find the electrical discharges, you’ve found the wind shear. Stages of a Thunderstorm All thunderstorms begin as cumulus clouds, build to an intense mature stage, and finally dissipate. - Page 18 Storm Mapping Principles UHF radio waves in the direction of interest and then receiving echoes from water droplets, whereas the Storm- scope system operates by receiving signals already present in the atmosphere due to electrical discharges. The Stormscope system analyzes the unique characteristics of these signals, their signal strength, and their varying rates of recurrence to determine the location and intensity of the thunderstorms that generated the discharges.

This process continues to replace old discharge points with new ones to make sure that discharge points on the screen represent the most recent electrical discharges.

Operation corresponds to the distance from the aircraft to the outer range ring on the screen. The Stormscope system stores electrical discharge information for all ranges simultaneously to provide you with an instant, up-to-date display of electrical discharge activity when you select a new range. As you move from one range to the next, the 25 nmi range is always indicated by a solid ring to advise you of your close proximity to thunderstorms. -
