Weather Display
CAUTION: NEXRAD weather data should only be used for long-range planning purposes.
Inherent delays and relative age of the WX data can be experienced. NEXRAD weather
cannot be used for short-term weather avoidance.
NEXRAD
High resolution radar image of radar reflectivity and lighting strikes.
Reflectivity is the amount of transmitted power returned to the radar receiver. The NEXRAD colors directly
correlate to the level of detected reflectivity from the radar.
To enable/disable NEXRAD press [MAP] -> [WX] -> [NXRD ON/OFF]
NEXRAD DATA AGE
The current age of the NEXRAD data is shown in the lower right hand corner of the map, 4 minutes old in
this example.
NEXRAD LIMITATIONS
• NEXRAD base reflectivity does not provide sufficient information to determine cloud layers or precipitation
characteristics. You cannot distinguish between wet snow, wet hail, and rain.
