So the comparison is 'flawed' is it? I agree that the comparison between a solicitor and accountant is more common than between a solicitor and airline pilot, but if you engage your brain you will see the similarities.
It is telling that, like in so many of your contributions on this site, you have failed to engage with any of the counter-arguments put to you. Instead, you seem content to decide whether a profession is a profession based purely on whether it has an institute with a royal charter! Are you aware of the self-serving and self-protecting nature of the traditional professional bodies? How many regular and mandatory assessments do solicitors sit once they have qualified? Doctors? Accountants? It almost seems that you are arguing that the CAA does not set standards. Please do elaborate, it is most interesting!
