Huh, I think I've flown with that guy...hell, I think he's our check airman. Let me guess, he's an old timer who thinks gps is less reliable than vor's, thinks analog gauges make more sense, fadec's are a waste of money, FMS's make people stupid, still files every airway and intersection on flight plans...blah blah blah.
Just jokin, but seriously, is he comfortable with new technology? I can't count how many times I've answered the PF's question of "What the hell is it doing?" with "Exactly what you told it to do".
No, he knows how to use FMS's. In fact he is now a Flight Safety Instructor. But, I have flown with that guy you mentioned above. Maybe not the exact same guy, but the same guy.
