So, what I'm hearing here is a reluctance to call in fatigued because of the chance of having to explain my decision to an ACP?

This is why we get paid the big bucks. If I have to make a safety decision based on a fatigued situation, I'm going to do it. Also, as a Captain, if my F/O is fatigued, We're BOTH fatigued. I won't leave him hangin' out there all by himself like I had a Captain do to me.

Let's see, end up in a flaming ball of fire at the end of the runway or talk to some knuckle-head cubicle driver in a set of dockers and cheap loafers....Hmmmm. Tough Choice!
