Totally agree with Keithl.
I too have a reputation for being a pedant when it comes to standards. For this, I am fully aware (although the FOs think I am not!) that I am one of the most unpopular Captains in their base.
FOs:us Captains were in your shoes once. Would you rather we didn't pick you up on sloppy operating and just tolerated it? We would like to think we are preparing you for your own command one day.
Some of the most tedious FOs to fly with are those who are perhaps in their second year of their first job, and tend to demonstrate the character flaws of being over confident and resilient to advice. I know..............I was one once!
