12.4.8.2 Weather Alert
The Weather Alert feature may be used to indicate the presence of heavy
precipitation beyond the currently displayed range and 80 to 320 NM from the
aircraft’s present position. Weather Alert targets appear as red bands along the
outer range ring at the approximate azimuth of the detected returns.
If a Weather Alert is detected within ±10° of the aircraft heading, a message
will be displayed in the Messages page. Touch the MSG key to view messages.

If the antenna tilt is adjusted too low, a weather alert can be generated by
ground returns. To avoid this issue, set the display range to less than 80 NM in
the terminal area. Weather alerts can also be deactivated in the terminal area.
