As far as standard seperation, i'll cover below FL245 coz I can't remember the RVSM stuff!
Analogue Radar Data:
3 Miles - When authorised below FL245
5 Miles - In Azimuth (side 2 side) - Between centes of radar returns and the returns do not overlap
5 Miles - In Range - Both a/c must be in coverage from same radar source
Plot Extracted data:
3 Miles - When authorised below FL245
5 Miles - In Azimuth - Both a/c within 80NM of known radar source
5 Miles - In range - Both a/c must be in coverage from same radar source
10 Miles - One or both aircraft outside 80 miles from single source but may be reduced by Authority.
I will be amazed if you are expected to know any of that for a board but, i think thats ure answer!
