Most of the CKA I have flown with are stellar pilots and are as humble as they are kind. They know they have a job to do and do it with the big picture in mind.
There are a few who just don’t get it. They feel that they have to be a hard ass and enforce arbitrary rule violations no matter the circumstances in which they occur. These are the guys you hate flying with. I had one debrief me that I needed to take the checklist all the way out of the holder when I read it because it looked bad. I always made sure the checklist was visible when I pull it halfway out.
I just chuckled and said ok thanks.
