(Ref. AMM TASK 29-10-00-863-003).
NOTE: The Blue and/or Green hydraulic system(s) operate(s) the slat system. If necessary, use the alternative hydraulic system.
NOTE: If you use the Blue Hydraulic System, an ECAM S/CTL SLAT SYS 2 FAULT message will show. This message can be ignored.
NOTE: If you use the Green Hydraulic System, an ECAM S/CTL SLAT SYS 1 FAULT message will show. This message can be ignored.
(3) Set the ECAM system to on (Ref. AMM TASK 31-60-00-860-001). D. Make sure that this(these) circuit breaker(s) is(are) closed:
