MAINTENANCE MANUAL
g Set the Antenna Tilt to full Up (U 15.0)
h Set Range to 240 NM.
i From the Aux Page, enter Maintenance Mode, as described in Section 6.3,
"Using the Maintenance Mode Page" on page 25.
j Press "Radar Setup".
k Press "Calibration" to display the RT CALIBRATION DATA page. Upon display of
the RT CALIBRATION DATA page with the system in calibration mode, all fault
fields will flash briefly. This verifies that the system is in calibration mode.
l Starting at -30 , slowly adjust the gain control downward until the antenna
clearance scan begins. This should take place at a gain value no lower that -26.
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.
Calibrate Radar Pitch and Roll.
a Use the right outer knob to set ROLL TRIM to 0 degrees.
b Calibrate AHRS ARINC 429 Pitch Offset.
Level aircraft.
Adjust the GAIN buttons for a GAIN POT /2 setting to 11- or 12-.
Set the PITCH ANGLE field to 0.0 +/- 1.0 degrees.
To increment the value of the PITCH ANGLE, use the left inner knob to change
the TILT SETTING to between 5 and UP. When the TILT SETTING is set to
between 5 and 10 UP, the value of the PITCH ANGLE field will slowly increase.
To decrement the value of the PITCH ANGLE, use the left inner knob to change
the TILT SETTING to between 5 and 10 DOWN. When the TILT SETTING is set
to between 5 and 10 DOWN, the value of the PITCH ANGLE field will slowly
decrease.
When the desired setting is reached, quickly adjust the TILT SETTING to above
10 UP to lock in the setting.
c Calibrate AHRS ARINC 429 Roll Offset.
Verify that the aircraft is level.
Adjust the GAIN buttons for a GAIN POT setting to 7- or 9-.
Set the ROLL ANGLE field to 0.0 +/- 1.0 degrees.
To increment the value of the ROLL ANGLE, use the left inner knob to change
the TILT SETTING to between 5 and 10 UP. When the TILT SETTING is set to
between 5 and 10 UP, the value of the PITCH ANGLE field will slowly increase.
To decrement the value of the ROLL ANGLE, use the left inner knob to change
the TILT SETTING to between 5 and 10 DOWN. When the TILT SETTING is set
to between 5 and 10 DOWN, the value of the ROLL ANGLE field will slowly
decrease.
When the desired setting is reached, quickly adjust the TILT SETTING to above
10 UP to lock in the setting.
