Rainboe,
We all make mistakes, I have made some as 'Captain' and have had them pointed out by my colleague before they became a safety risk. Thanks were in order and a debrief and review of my own performance. Not a problem in any way, just a good way of improving my own performance.
If you think you are a 'flying god' due to passing some airlines command course then good luck. They train/convert Captains based on commercial need, not necessarily skill/personality/capability or in your case lack of.
We are all now commercial entities, nothing more nothing less. When you hit the minimum requirements then they will feed you through the command minching machine and out you pop, as Rainboe, an all knowing, dismissive, bitter entity.
Cheers
W2P
