PREDICTIVE HAIL AND LIGHTNING (Hazard Display Feature)

If the Hazard Display Configuration of the radar system is installed,
icons will be displayed on top of the reflectivity to identify areas that
have the signature characteristics of hail, lightning, or both.
For hazard display use the following procedure:
1. System Control: 1 or 2 (dual system) or 1
(single system)
2. HZD Pushbutton: Engaged
3. Mode: ALL/ALL WX or
ON PATH/ PATH WX
4. Range: As desired.
The radar does not directly detect hail or lightning; it analyzes the data
in the 3D memory to identify areas that have a high probability of
containing these hazards.
Hail and lightning icons indicate that conditions in the associated
weather cell are conducive to the development of hail or lightning. They
do not guarantee that hail or lightning will be present, nor does the
absence of an icon guarantee that the condition will not be present.
Note that an icon cannot indicate the exact location of any expected hail
or lightning. Treat the entire weather cell or area as a threat.
See PLANNING A PATH on page 40 for details on how to utilize the
information provided by the Hail and Lightning Icons.
