WEATHER RADAR SYSTEM
The airplane may be equipped with P-660 or P-880 weather radar
models and 12 inch antenna. For additional information on functions
and operations, refer to the manufacturer’s manual.
The weather radar system is designed for detection and analysis of
precipitation in storms along the flight path of the airplane. The system
provides the flight crew with visual indications regarding turbulence
content (P-880 only) and rainfall intensity.
Precipitation intensity level is displayed in four bright colors (magenta,
red, yellow and green) contrasted against a deep black background on
the PFDs’ and MFDs’ radar mode field. Magenta represents the
heaviest rainfall intensity while green indicates the lightest.
The radar may also be used for ground mapping. When operating in
ground mapping mode, prominent landmarks are displayed, which
allows identification of coastlines, mountainous regions, cities or even
large structures.
