Hazard Avoidance
Removing Ground Clutter
The optional Ground Clutter Suppression (GCS) feature which is available on either
the GWX 70/75, the system can distinguish between reflected ground returns (such as
terrain features and buildings) and airborne weather phenomena. Ground clutter may be
most pronounced when using a low antenna tilt angle, or when approaching mountainous
terrain.
NOTE: The GCS feature of the airborne weather radar may remove the display
of low-intensity precipitation in addition to ground returns when the feature
is enabled.

annunciator is green; ground clutter suppression is disabled when the

displayed as red bands along the outer range ring at the approximate azimuth of the de-
tected returns.
If a Weather Alert is detected within ±10° of the aircraft heading, and the WX ALRT
Softkey is enabled, the system also displays an alert on the PFD in the Alerts Window.
