3M WX-11 Stormscope

The WX-11 Stormscope is more advanced than the WX-10 and WX-10A because it is gyro stabilized. It uses the bootstrap output from your HSI to keep the display oriented to the current aircraft heading during turns. On a Stormscope that is not gyro stabilized, after a turn, the pilot should clear the display to allow the activity to be detected on the new bearing. This is not necessary with the WX-11, since the display has "turned" with your aircraft. Consider this as an example: There are electrical discharges detected straight ahead. The pilot makes a 90 degree turn to the left. Now the display will correctly show the storm off the right wing. A display that is not gyro stabilized will still show the activity straight ahead until that information expires. This is a great feature to reduce pilot workload and improve situational awareness. Using a gyro-stabilized display is most helpful when maneuvering during departure and approach, when the pilot is busiest. The other WX-11 features are very similar to the WX-10 and WX-10A. The WX-11 System consists of a display, remote processor, and an antenna. This Stormscope offers thunderstorm information on a bright green CRT display. The more the dots on the display are clustered together, the stronger the storm activity. Up to 256 dots may be displayed. The WX-11 also has a Forward mode to concentrate the display and processing power on the airspace ahead of you. The WX-11 Stormscope features:

Choice of display ranges: 25, 50, 100, and 200 nm
Stores lightning data in all ranges simultaneously, making it easy and useful to toggle between them
360° view of surrounding airspace or 180° view of forward airspace
Clear function to help determine storm intensity and movement
Test function to verify proper operation
Gyro test function to verify proper heading input (If your HSI has an electronic fault output, the WX-11 can display a warning flag if detected.)
