David I haven't stepped in until now, have just been watching this and other posts grow, with morbid fasination.
What you have in your hands as a PPL holder is a licence to learn, nothing more nothing less. You have met the basic requirements needed to hold the licence, nothing more.
I was told by one of the many examiners that I have had that with the PPL the examiner was happy for me to fly him as a passenger. With the CPL he was happy for me to fly his family. With the ATPL, I leave you to guess that.
Please be aware that the examiner passed you for one reason, on the day you carried out the sections of the PPL test to the required level of competence, nothing more.
It is a licence to learn, many have gone before you who don't want you to make the same mistakes they did. Please learn from them.
Its an unforgiving enviornment we operate in, when it goes wrong it tends to big time. Don't let your attitude make you the next statistic.
