Aug 01/05 CES A. Aircraft Maintenance Configuration
(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002)
(2) Do the ADIRS start procedure (Ref. AMM TASK 34-10-00-860-002)
(3) On the EFIS control panel of the FCU:
- set the mode selector switches to ARC
(4) on the center pedestal, on the WEATHER RADAR CONTROL-UNIT (3SQ), start the weather radar system.
(5) On the FO EFIS switching panel 500VU:
- push the PFD/ND/XFR pushbutton switch until the FO ND comes into view on the FO PFD DU
- make sure that the FO PFD potentiometer (8WT1) is in the center position.
B. Make sure that this(these) circuit breaker(s) is(are) closed:
