Annex D makes interesting reading. 68 occurences over a period of 2 years 10 months i.e less tha one per fortnight. There do not appear to have been many if any significant conflicts.
More to the point a quick reading would seem to suggest that out of the 68 some were plainly outside the proposed class D i.e. No 48 -16nm north west, 53 - 6nm west low level, some may well have been outside, eg nos 22, 27,28, 34 etc. In all there appear to be about 25 + that do not clearly appear to have been within the proposed class D airspace; so over one-third. Two occurrences appear to be London Mil refusing to take traffic because of workload.
If one ignores the 25 we are left with 43 in a 34 month period so an average of 1.27 occurrences per month.
I'm due to fly from Norwich in a fortnight - do you think I should cancel?
