Litebulbs, please get your logic sorted out! You said
Flying aeroplanes does not make you a good leader. I am reasonably sure that leadership is not a prime measure, when promoting a first officer to command. It would never have been in the job role. Hiding behind the law of the sky, does not promote good leadership skills.
In most other jobs, leaders are selected because of their leadership skills. This is true for cabin crew. is it the same for flight crew?
So do you have any doubt the pilot has leadership skills or not? Because to say
I would never say that a Captain would not be able to manage as you have said. If I had any doubt, I would not fly.
is a contradiction. this thread is convoluted enough without people making contradictory statements! You evidently don't have confidence that leadership/management skills are adequately assessed at 'promotion to captain'-time!
