TR-1 TRANSMITTER/RECEIVER 
The Transmitter/Receiver contains the electronics necessary to transmit, receive, and process the radar pulses used to detect turbulence, windshear, weather, and terrain targets.  It also contains the system integrity monitoring and self test electronics.  The TR-1 is located in the radome in the base of the antenna drive. 
 
DA-1A/B WITH FP30-1 ANTENNA DRIVE 
The component parts of the antenna drive are the DA-1A (single) or DA-1B (dual) Antenna Drive and the FP30-1 flat-plate array.  The antenna drive, located within the radome, forms the microwave energy into a 3 degree beam.  The antenna also receives the return microwave energy, after reflection by weather formations or other objects, and routes these signals to the transmitter/receiver for processing.  The antenna drive scans a 160 degree sector in azimuth and ±15 degrees in elevation (tilt). 
 

 

CP-1A/1B CONTROL PANELS 
The CP-1A/1B contains all controls for operating the radar system except those located on display units or electronic flight display control panels.  The CP-1A is used in a single system configuration while the CP-1B is the dual system control panel. 
One new aspect of the RDR-4000 is the ability to show two different radar display views simultaneously.  The left side of the control panel controls the left side display (Captain) and the right side of the control panel controls the right side display (First Officer).  The flight crew can operate each side independently without impacting radar performance, achieving maximum weather information display. 
ELECTRONIC FLIGHT DISPLAY 
The Electronic Flight Display is not part of the RDR-4000 system, but is where the radar mode or status, weather returns, windshear, turbulence, and ground map data are displayed.  This picture is intended as an example only.  Your equipment may vary.
 
 
The Electronic Flight Display Control Panel is not part of the RDR-4000 system, but is used to select Weather Radar (WXR) for display.  This picture is intended as an example only.  Your equipment may vary.
 

 

OPERATING CONTROLS 
When WXR is not selected on the display system, no radar display is shown.  While in the air, or on the ground if the radar has been auto-activated by qualifiers, the radar will nevertheless continue to operate, constantly updating the 3D memory so that current radar data is immediately available whenever WXR is selected.  (Typical auto-activation qualifiers are Engine at Take-Off Thrust Setting or both Oil Pressure Active and Transponder On.  See AUTOMATIC WINDSHEAR ACTIVATION on page 14.) 
When approaching a gate, deselect WXR on all displays and/or select TEST on the control panel to prevent the radar from transmitting.
SYSTEM CONTROL
(CP-1B)
L: Selects left system for normal weather operation. 
R: Selects right system for normal weather operation. 
(CP-1A)
NORM: Normal weather operation. 
 
(CP-1A/CP-1B)
TEST: Selects test mode and provides a test pattern to allow verification of system operation and fault isolation.  While on the ground, the system test will also exercise the windshear aural and visual alerts shortly after being selected.  If the system control is placed in TEST while in flight, the display will show the test pattern, but no windshear aural or visual alerts will be annunciated.  If a windshear event is detected while in the test mode, the display will switch to weather with the windshear icon overlaid, and warning or caution annunciations will be triggered, as appropriate.  

MODE SELECTION
 
MAP – Displays Full Coverage Ground Map 
 
AUTO – Automatic Weather Presentation Mode  Provides display of windshear out to 5 nm, turbulence out to 40 nm and weather out to 320 nm. Secondary weather returns are shown with black stripes through them.
