- do the inspection after flap/slat extension at more than the flap/slat limiting speed (VFE) (Ref. AMM TASK 05-51-13-200-001).
(2) With the warning message on the upper ECAM DU: "VLE........280/.67":
- do the inspection after landing gear extension at more than the geardown limiting speed (VLE). (Ref. AMM TASK 05-51-12-200-001).
(3) With the warning message on the upper ECAM DU: "VMO/MMO.......350/.82":
R (a) In the avionics compartment, on the panel 188VU, make sure that R the L/G DOWN VMO/MMO SELECTION switch 22FP is safetied in the position related to the aircraft last flight conditions: - in normal flight condition the switch 22FP must be safetied with lockwire in NORM position
- in flight, with landing gear down condition, the switch 22FP must be at L/G DN.
