@mad_jock - Thanks yes I have seen that and it the opening line is where my question is
"Is this flight Private? Public Transport? or Aerial Work? => See the Air navigation Order 200, Article 130"
This refers to something that does not exist now.
@mickjoebill - thanks
I have now located CAP 393
http://www.caa.co.uk/docs/33/CAP393.pdf Section 259 to 270 Part 34.
Anyone have an understanding of this in relation to my OP
