WEATHER DETECTION
AUTOMATIC WEATHER MODE
(ALL/ALL WX or ON PATH/ PATH WX)
GENERAL DESCRIPTION
The ALL/ALL WX and ON PATH/ PATH WX
modes provide weather, turbulence, and
predictive windshear detection. The system processes the data to fill
the 3D memory and extracts the selected data for display. When a
PWS event is detected, an icon is shown on the display. Returns
determined to be ground clutter are not shown.
Weather targets are color-coded by the intensity of the return. The
display correlation to approximate rainfall (with Gain set to AUTO) is as
follows:
Reflectivity Color Codes (Gain at AUTO)
Color Returns Reflectivity Rainfall Rate
Black Very light or none Less than 20 dBZ
Less than 0.7 mm/hr
(0.028 in/hr)
Green Light 20 – 30 dBZ
0.7 – 4 mm/hr
(0.028 – 0.16 in/hr)
Yellow Medium 30 – 40 dBZ
4 – 12 mm/hr
(0.16 – 0.47 in/hr)
Red Strong 40 dBZ or greater
Greater than 12 mm/hr
(0.47 in/hr)
Magenta Turbulence N/A N/A
ON PATH/ PATH WX WEATHER
The RDR-4000 fills the 3D memory with all the detected weather in front
of the aircraft out to 320 nm, and from ground level up to 60,000 ft mean
sea level (MSL). The RDR-4000 displays weather along the flight path
(designated
flight path weather) using solid colors. All other weather is
designated as off path weather. When in the ON PATH/ PATH WX
mode, only the on path weather is displayed.
The nominal flight path weather envelope is ±4,000 ft with respect to the
expected flight path. At cruise altitudes above 29,000 ft MSL, the floor
of the envelope is extended down to 25,000 ft MSL when necessary to
ensure that relevant convective activity is displayed. On the ground and
during departure or approach, the ceiling of the envelope is fixed at
10,000 ft MSL. This provides approximately 10 minutes of look-ahead.
