BIK - if PPRUNE is only for Professional pilots then why do you post?
If you are who others infer you are then you are certainly not and never have been a Professional Pilot. Owning your own aircraft is not a qualification for that and of course that would be, therefore, (another) arrogant and disrespectful assumption for you to make such claim. I believe one, two or more pilots who grew from GA would support that point.
BTW I am a Pilot and I was a 'PAYE' pilot so I guess that makes me a professional pilot. I did not pay for my licence, pay for my aircraft and just go for a jolly old fly and then call myself a professional pilot with the biggest and best knowledge of all things aviation. Bit different mate!
Touche' for me - but again why do you again arrogantly insult a part of the industry (ATC) when you have no qualification and clearly little knowledge of? Most ATC's I have met, have or do fly. They and the airport operators provide a valid angle and input to this debate. Why oh why should you wish to exclude them?
