I don't think that the United MEC's point is that one airlines proceedure is better than another. The issue is that there are significant changes being made to the proceedures that the United pilots are having to follow that they are not being adequately trained for. It would obviously be better to have everyone run thru the proceedures in a sim or at least an FBS before going live with them, but the company isn't willing to pay for it. You can argue over whether or not that is necessary, but it is no doubt safer. I believe that two LCA resigned over the issue. As for advising the CO MEC first, that would have been prudent, but at the same time the CO MEC has done things to get the United MEC's back up including the intransigence on pay banding and demanding pay records for all of the United pilots. Cooperation is a double edged sword.
