If it's any consolation at all, I started with NATS in 1992 wanting to work at an airport. To my (then) disappointment my course was designated all area. The initial disappointment was
VERY short once we got on with things, although in those days we did still do the aerodrome rating course. I then managed to flunk my training at a later stage and I'm now ADC/APR at a regional airport, so it all turned out for me. Sometimes these things just take a little time
My advice? Go to the college, do the course, get to your unit and enjoy!
