MP,
Good on you for talking about the situation you found yourself in and the punishment the CAA gave you. I think it demonstrates laudable self criticism and am not sure many posters in this forum would do the same given the circumstances.
There are many "perfect pilots" on this forum whose egos exist in a rareified reality. Firstly they would never ever get into the situation you got into and that would enable them to be highly critical of your judgement
etc... . Furthermore they would go on to accuse you of using the thread as a confessional -
.
Dear dear...
Certain expressions come to mind but the politest one contains the words "pride" and "fall"...
So, MP; all the best with progressing your professional flying career, I'm pretty certain you won't let a navigational ballsup of this scale happen to you again, and that when you are captain of the heavy that has to go around because of an infringer you will view the situation more forgivingly.
None of us are perfect, (not even me!)
