a couple of questions......
I'm doing part2 of selection next month and i've been swatting the booklet that was sent. there are a couple of points i don't understand and would appreciate a bit of guidance:
1. if class D and E are controlled airspace does that mean all aicraft have to be under radar control or can ris/ras be applied?
2. it says heathrow and the channel isl control zones are class A airspace and yet other zones are class d- why is this? and again what level of service must aircraft be under?
3. again to do with airspace classification and services. what class are CTA's and TMA's and what service must aircraft be under?
4. finally, do atco's always assign levels according to semi-circular or quadrantal levels or is this system only used by aircraft not under a service.
Apologies if these are dummy questions but thanks in advance.
