Help With Comm

[Zedd]

Hi All,

Just about to do my final comm test and need to finish a comm prep before this happens. Was wondering if anyone out there could help me answer a few questions. It would be greatly appreciated.

1. Is the speed restriction of 250kts at 40nm into johanesburg still in force?
2. Difference between Radar Identified, Radar Controlled and Radar Vectors
3. What are the South African rules with regard to the Approach Ban.
4. ICAO missed approach procedures during a circling approach.
5. ICAO altimeter setting procedure.
6. Allowed reductions on take off minimas for Lanseria departure aerodrome

Thanks for the help,
Zedd
