Well, if that's your standard of competency it's time for me to stop flying! In my book a COMPETENT pilot should not make such an INCOMPETENT mistake as this.
Hotel Tango, I am struggling to comprehend your post. Are you suggesting that because you have such a high level of competence you are you not going to make a mistake of this magnitude - or any mistake?
Or perhaps you are suggesting that there are competent mistakes and incompetent mistakes - and that the only mistakes you make fall into the competent category?
If you don't believe that you have the potential to succumb to any of the psychological factors that effect human performance, then I would suggest you haven't learned much about flying yet.
