VH,
Anyone that has flown "corporate" understands the situation...."I/we just have to make this meeting....no matter what we just got to be there...a lot is depending upon this meeting....mindset."
Call it CRM or just plain old commonsense...if one is to err....do it on the side of safety. The "doing" of that is where the problems come in.
Diplomacy and deference can only go so far in these situations and at some point if it gets to that point where one must hoist the BS flag.....run it up the flagpole in a very smart (as in quickly with elan) military fashion.
I always assumed when the other pilot asks what I think of the weather....he really is making a declarative statement and not an interrrogatory. I rarely said things were right as rain but usually suggested I was having second thoughts as well, thus making his decision much more likely to be the cautious one.
We can learn from others.....but one must make sure the bolder way is within good safe parameters.
