Been enjoying this thread, and it has caused me to think about some issues I've had. Zero 121 experience, the mix of people definitely provides a different experience from 91.
I've got tons of time dual given, not just in Skyhawks (the bugsmasher version) but in king airs and high performance pistons twins. So I probably come into the cockpit of a multi crew jet with some annoying attributes.
I never hover over anything. I always ask the pilot flying what he thinks before i key the mike, and I always dig for criticism over a beer after our leg for the day. (Tough day if it's two legs)
With a fully qualled FO, we swap legs short of circumstances that would prevent it, and I've gotten shock with confidence building legs downs to mins that I was informed other captains would have never allowed.
That being said, I've received criticism from other (young inexperienced) FO's that I'm teaching or "quizzing". My perception on the "quizzing" would be me asking what would they would do or the occasional curiosity about his level knowledge of something. I view teaching from the left seat as part of my job. In the corporate world, in my experience, FO is a temporary position while everyone figures out you're ok to be a co-captain.
So I see the same animosity in some of the responses in this thread that I've perceived from a couple (millennial) young fellas flying next to me, and I'd like to improve as a captain, but I'd also like to know why you don't think the guy with the grey hair next to you shouldn't be giving you some guidance and mentoring.
It's difficult for me to find a balance between doing my job and letting them do their job and also trying to bring them along in the industry. (They can fly the airplane and I'm not talking about corrections of something wrong or dangerous. I'm talking about developing young guys/gals into captains.)
I hope i get some good responses and I hope this question helps out some other relatively inexperienced captains thinking similar things...
