5.5.4.11.3.1 Honeywell (Bendix/King) 2XXX Series Radars
This section describes Post-Installation System Configuration and Calibration of the Bendix/King RDR-
2000 and RDR-2100 Radar Systems using the GTN 7XX. The CM 2000 Configuration Module for the
WXR must be configured using the Honeywell (Bendix/King) KPA 900 Configuration Module
Programmer Kit (P/N 050-03311-0000) in conjunction with a personal computer. Refer to the
configuration module programmer operator’s guide for detailed setup instructions. Follow the instructions
for the programmer, and any required weather radar settings contained in Section C.17.
Weather Radar Calibration Mode
Place the WXR in calibration mode as follows:
1. Go to the Weather Radar page in the External Systems page group.
2. Set the Radar Mode to Test.
3. Touch the Calibration key and wait for the WXR to enter calibration mode – all status indicators
will flash briefly to indicate that the radar is in calibration mode.
Antenna Clearance Check
Perform the antenna clearance check as follows:
1. Ensure that the WXR is in calibration mode.
2. Adjust the Gain field to a value of -26.5 to -28.0, and set the Tilt Settings field to 14.75°U. This
will initiate the antenna clearance scan. The antenna will move to each of the extreme positions to
determine that there is no interference with antenna movement and all scan motors are working
properly.
Stabilization Calibration
Perform the WXR stabilization calibration as follows:
1. Ensure that the radar is in calibration mode.
2. Note the Roll Trim value for re-entry following the stabilization calibration procedure. Adjust the
Roll Trim field to 0.000.
3. Beginning with the 400 Hz REF GAIN procedure in Section 2.4.4.1, follow the instructions in
Section 2.4.4.1 of the RDR 2000 Installation Manual (Honeywell P/N 006-00643-0007) or the
RDR 2100 Installation Manual (Honeywell P/N 006-00648-0002).
4. If the roll trim value was recorded from the previous WXR indicator or noted in step 2, set the
Roll Trim field on the GTN 7XX to this value.
5.5.4.11.3.2 Honeywell (Bendix/King) RDS 8X Series Radars
This section describes Post-Installation System Configuration and Calibration of the Bendix/King
RDS-81 (RS 811A) and RDS-82 (RS 181A) Systems using the GTN 7XX.
Weather Radar Calibration Mode
Place the WXR in calibration mode as follows:
1. Go to the Weather Radar page in the WXR page group.
2. Set the Radar Mode to Test.
3. Touch the Calibration key and wait for the WXR to enter calibration mode – the RX TX box will
turn red when the radar enters calibration mode.
