Smash Bugger:
I note that you mention the "No Technical Objection" caveat that I guess your airline uses to allow the use of F/Ds below MDA on NPA approaches however I have had a chance to review my own airline's manuals and, guess what, we do not have this facility!! Perhaps many other operators are the same?
As I said before, I chose to answer a simple question in GENERAL terms and you jump in here and criticise me in very SPECIFIC terms for not being 100% accurate!
Please explain to me how your posting has helped the OP in his understanding of Airbus procedures?
