HAZARD AVOIDANCE
6.1 WEATHER AVOIDANCE
STORMSCOPE® (OPTIONAL, COLUMBIA 350 ONLY)
WARNING: The Stormscope system is not intended to be used for hazardous thunderstorm penetration.
Weather information on the G1000 MFD is approved for weather avoidance only.
NOTE: Refer to the WX-500 User’s Guide for a detailed description of Stormscope operation.
NOTE: Heading information must be valid in order to display Stormscope lightning data on the Navigation
Map Page. If heading information is lost, strikes and/or cells will not be displayed on the Navigation Map
Page.
The Navigation Map Page (Figure 6-4) and Stormscope Page (Figure 6-8) display cell and strike data using
the yellow lightning strike symbols shown in Table 6-1.
The Stormscope® system detects electrical activity generated by cloud to cloud and cloud to ground lightning
strikes associated with hazardous convective weather. Stormscope receives electrical discharge information and
processes it to determine range and azimuth from the aircraft.
The detected electrical information is sent to the G1000 to plot the location of the thunderstorm activity on
the Navigation Map Page and the Stormscope Page.
Stormscope works on the ground as well as in the air giving planning information before takeoff.
