IMHO, what is needed now, is the final investigation report. The A320 in this thread has now been redesigned, rebuilt several times and Airbus SOPs amended a dozen times by people with no knowledge or experience of A320 operations. If Airbus SOPs are deficient in this area, I'm sure Airbus would have informed all A320 operators by now; so give it a rest and read the entire contributions to this thread before suggesting a repetitive theory and how to fix it.
