Eye - with regard to PNF querying any setting, clearance, etc. - My last company had what I reckoned was an excellent policy which dictated that, when either pilot was unsure ("Was that heading 220 or 200?") the PNF immediately queried it with ATC. Too often a junior FO will not feel able to do so with a Captain of the crusty variety ("I darned well TOLD you it was 220, you young whippersnapper, but you didn't believe me") so such a policy takes the possible argument out of the equation.
And Vectors:-
Your very nice Guild Chairman invited me to speak at the last conference. He had hoped that I would upset as many people as I did at the NCL ShAirSpace Forum. Unfortunately I failed to live up to his expectations.
Sorry Richard!
I have no particular problem with the concept of upsetting people if it gets topics out and aired, and a "free and frank" exchange of views going!
