Good heavens - so many points:
PPruNe radar: Thanks
Dog on Wheels: Well done - not an easy post to write!
Cleared to Land 27 Left: You don't need to be a spotter. I take the **ss out of spotters, but if anyone tried the same with me BECAUSE I know an ATC Worthy fact about an aircraft type they would get a right mouthful! You don't need to be a spotter, but I personally believe a general interest in aviation is so very important and a pre-requisite for the application form. You don't need to know too much, as CATC has A/C Characteristics Lesson's in the syllabus. (And there is a very good self-study CBT).
It is all about professional pride.
Anyway, good luck to the next generation of 6 weekers. If anyone comes to us, see ya then!
