HAZARD AVOIDANCE
Displaying Precipitation weather information:
1) Select the MAP Softkey (for the PFD Inset Map, select the INSET Softkey). This step is not necessary on the
Weather Data Link (CNXT) Page.
2) Press the PRECIP Softkey.
The system displays either base or composite NEXRAD imagery, depending on the region.

Radar Reflectivity Type
Composite Reflectivity
Base Reflectivity
The base reflectivity precipitation weather product shows the radar returns from the perspective of a single
antenna tilt angle. The composite reflectivity precipitation weather product shows the highest radar energy
received from multiple antenna tilt angles. The display of the information is color-coded to indicate the
intensity of the echoes and the type of precipitation.
All weather product legends can be viewed on the Weather Data Link (CNXT) Page. For the Precipitation
legend (Figure 6-69), select the LEGEND Softkey when Precipitation is selected for display.

The display of No Radar Coverage is enabled when Precipitation is selected for display. Areas where
precipitation radar coverage is not currently available or is not being collected are indicated in gray shade of
purple. A white boundary line with white tick marks depicts the selected coverage area of the Connext Data
Request. This boundary encloses the precipitation data when this weather product is displayed.
Reflectivity
Reflectivity is the amount of transmitted power returned to the radar receiver. Colors on the Precipitation
display directly correlate to the level of detected reflectivity. Reflectivity as it relates to hazardous weather
can be very complex.
The role of radar is essentially to detect moisture in the atmosphere. Simply put, certain types of weather
reflect radar better than others. The intensity of a radar reflection is not necessarily an indication of the
weather hazard level. For instance, wet hail returns a strong radar reflection, while dry hail does not. Both
wet and dry hail can be extremely hazardous.
