First of all I have no issue with your last paragraph in the most part. It is the other ones I take issue with. I never said I was Capt Smoothride. The issue in question was that the charter client was not comfortable with the f/o. I don't know why and not able to find out. I believe it was due to the f/o's interaction with the client. But in a small two aircraft charter operation, if a $60k a month client requests something, if it doesn't adversely effect safety, he generally gets it. In the corporate enviroment, if it doesn't adversely effect safety, what the CEO, COB or President wants, they get. Remember, if they become unhappy with the service (and this is a service business) it is you the gets the ax, not the VP who you answer to. Safety is another issue. Remember these people directly sign your paycheck. At this level, they don't have to be reasonable, they are the boss and they know it. I have seen a pilot fired because he didn't use enough brake on landing. And a flight department shut down because the pilots ran an aircraft off the end of a runway. Airline crews are a little more fortunate in that the passengers have very little input in who flys the aircraft. About the only thing they can do if they are unhappy is put their butts on someone else's airline. While airline crews are more or less insulated from these issues, in the charter or corporate world, I fight the battles that are important and save my political capital for the times I need it. Like being told to go below minimums or use a runway that is too short, etc.
As a check airman, I generally know what I have to work with, as I most likely did their checkride. But checkrides do differ from regular line flying. And a checkride is just your authorization to go out and learn. Back when I just a simple line pilot, the first leg a new f/o flew would normally be a non-passenger leg. It usually ended up being the first leg of the day. And Yes, it was because I wanted to see what I had to work with. And I don't apoligize about it either. I was fortunate to work with some very excellent Captains early in my career and the advice they each gave me when I upgraded was very similar.
Use good judgement.
Know your limits.
Know your F/O's limits.
Fight the battles you need to fight.
And stop putting words into my mouth. The main thing I have been advocating is that PIC's must exercise good judgement. They must keep in mind not only their limitations but also the F/O's limitations and use that information accordingly. And it varies from aircraft to aircraft and from operator to operator. A Part 121, B737 operator going between long ILS runways has different considerations than a Part 135 air ambulance Lear 24 operator doing night flights into Mexico.
I expect and insist that my f/o's know the aircraft systems and procedures. But it has been my experience that you have to start flying the aircraft before you really start to learn it. By that I mean all the little things they seem to miss in ground school. Like how do you unstick a frozen brake on the runup pad. Or how do you deal with a stuck start valve. That fuel rolling up over the tip tank, did someone forget the fuel cap or is the vent line check valve stuck. You don't learn that in ground school, you learn about that when it happens to you. And my f/o's and I quiz each other on limitations and emergency items. Usually before checkrides. I try to keep it from being too much like a checkride, mostly to prevent personality issues.
