Turbulence Detection
The optional Turbulence Detection feature, available with the GWX 70/75, identifies
areas of turbulence associated with precipitation using the color magenta (GWX 70) or
white (GWX 75) during a horizontal scan. The magenta or white areas represent precipi-
tation moving at a high rate of speed either toward or away from the radar antenna, using
Doppler radar measurements. This feature cannot detect areas of Clear Air Turbulence.
Enabling/Disabling Turbulence Detection during a Horizontal Scan:
1) Select the 'Map - Weather Radar' Page.
2) With the radar in weather mode, press the Features Softkey.
3) To activate or deactivate the turbulence detection feature, press the TURB
Softkey. Turbulence detection is enabled when the softkey annunciator is
green; turbulence detection is disabled when the softkey annunciator is
gray. The system indicates the current turbulence detection feature status
in the upper right of the 'Map - Weather Radar' Page.
