Take over
If the captain decides to go below mins with nothing in sight, take over the aicrcraft and get the hell out of there! Not only is this the correct answer on for any self-respecting airline's interview, it's the only thing you, as a self-respecting individual, should do. How dare anyone place you, and/or the pax, in danger! What gives him the right to perform anything for which he was not trained and is assuredly deemed unsafe by the FAA?
If there are any repercussions or ramifications persuant to your decision to stay alive and physically intact following such an event, then quit your job and go somewhere else, either in aviation or outside thereof. No one or thing in civilian aviation is worth risking your life for............especially for simply quelling your fears of reprisals or future career detriments! If during any subsequent interviews you are questioned about your aforementioned decision, leave that interview and go somewhere else as well!
The government has spent untold billions of dollars trying to find out why airplanes crash and how to prevent their future occurences. The cockpit voice recorder is one of the devices spawned from their quest and it is not intended to defend you following a cockpit confrontation. It is there to allow the dead to speak with a very loud voice and appologize for not speaking up sooner. The primary contributing factors in most aircraft accidents have been determined to be "lack of crew communication, coordination and assertion"................in other words,"CRM." Which, by the way does not stand for, "Captain runs the Machine."
Bruised egos and timid subordinate crew members have long been the reasons why so many unnecessary and easily-preventable accidents (on purposes?) have occured. It's time for this nonsense to stop!
Modern aircraft don't have two pilots just so one of them can "run the radios." All of my F/Os are explicitly directed to call my attention to anything that they may feel is amiss. If I'm wrong, I say to them, "Thank you." If they're wrong, I say, "Thank you for questioning me and not being afraid to speak up." There should never be any embarrassment or hesitation when it comes to questioning the "other guy."
I'd much rather be challenged by an F/O (even when I'm right) than be buried because he was trying not to hurt my feelings or his career.
Careers are replaceable, lives are not!
Oh, by the way, Wiggums, if your captain gets pissed because you "called the tower" right at the MAP, his actions are probably justified since he didn't tell you to do so (Did he?).
If he did tell you to call the tower, he's an idiot for geting pissed and an even bigger one for being in such a hurry to have you "call the tower" at such a task-oriented time. Shouldn't he be worried about aviating rather than communicating?
Don't ever die "with a mike in your hand!"
