When I was learning in Canada (Shearwater, NS), there was a colour coding scheme used when booking out on the radio with ATC:
- Red - Student Pilot
- Yellow - PPL < 100hrs
- Blue - PPL >= 100 hrs
- Green - Instructor / CPL
This worked very well. Also, when I was completing my PPL @ Bournemouth, when booking out by phone, we sometimes used Code A / B / C / D (similar categories to above) - that seemed to die out.
I fully endorse Evil J's suggestion that it should be a standard part of the booking out routine. Certainly in Canada, it seemed like the ATCOs were a little bit more precise with their instructions, gave you chance to digest each message and gave you info in 'bite size chunks'.
