Centaurus,
Just curious,why descend at 250kts with one engine until 13000ft? Would you want to get there sooner with 300kts or 320kts?
Had 6 flaps related faults upon approach. IMHO,best thing to do is recycle flap lever,if no good,select to a smaller flap setting(as per split flap checklist) go somewhere to hold,wait at least 2 mins before proceed further into the checklist.Somehow after a short wait,the split protection hydraulic cutout resets
itself and you will see the flaps retract to the smaller position(if the drives are ok).Then reselect flap as schedule,99% normal config for landing.
