BENDIX/KING
The radar antenna may be observed from the front of the aircraft during the following procedures
because the radar is not transmitting while in the TEST mode. However, the MPEL boundary
should always be observed when the radar is operational.
If the ART 2000 is installed in a EFS 10 or EFIS 40/50 system with software level 08 or earlier,
proceed to Section 2.4.4.2.
If the ART 2000 is installed in an EFIS 40/50 system with software level 09 or above, proceed to
Section 2.4.4.3.
2.4.4.1 Stabilization Calibration with Radar Indicator
The following procedure assumes that either analog or ARINC 429 stabilization inputs are
present. The following procedures may also be used if an IN 812A Radar Indicator is used in the
system.
The following procedures are performed by utilizing the GAIN knob, RANGE buttons and the
mode buttons on the radar indicator.
Enter the maintenance mode by performing the following procedure.
A. Set the radar function selector to TEST. Turn the GAIN knob to minimum.
B. Set the antenna tilt to full up and select 240 NM range.
C. Simultaneously press the Wx and WxA or Wx/WxA and VP buttons (depending on whether
Vertical Profile is supported by the indicator) to display the maintenance menu. See
2-3.
D. Press the RANGE UP button to display the RT CALIBRATION DATA page. See
E. Upon display of the RT CALIBRATION DATA page with the system in calibration mode,
the fault fields will flash briefly. No faults should be displayed when the fields stop flashing.
This verifies calibration mode is entered. Adjust Roll Trim for 0
F. 400 Hz REF GAIN
If an ARINC 429 gyro is being used, proceed to Step K.
1. Set the tilt table to 0
2. Adjust the GAIN knob for a GAIN POT setting between -28 and -30 (see
2-10). An 01 should be displayed in the AZIMUTH COUNT field
Page 2-22
NOTE
Failure to perform Steps A and B will prevent the
ART from entering calibration mode. If more than
one radar indicator is installed in the system, all but
one indicator must be in the OFF or SBY position in
order for the system to enter the calibration mode.
