The problem with DEC commands as we saw with the ASL entries is the highly variable standards of the applicants and those that arrive into the CX training system. Some were excellent, some were trainable and some were, as an American FO said to me at the time, "Don't you guys know who this is, he is unemployable in the USA ."
That was when CX had a robust (some would say anal and up themselves) training system. I believe nobody who got through as an ASL captain was unsafe. The politics of their admission was appalling, just as now, but I fear that now the training system will have been directed to have a, "bums on LHS at any cost," approach.
