DavidReidUK,
<< No, they aren't saying that at all. The document is clear that airport operators can propose a different separation standard (with suitable procedures) as an alternative means of compliance (Section 4):
"The CAA will consider an application from aerodrome licence holders to apply an alternative specific Heavy/Heavy aircraft departure wake turbulence separation."
(and would require)
"In addition to promulgation of the alternative separation standard in UK AIP AD2, evidence that aircraft operators were aware of and content with the local variation."
That's "alternative" as in an alternative to 4nm separation (subject to a safety case, obviously).>>

Sorry now completely lost me in this gobblydeegook.
We are still no nearer at all in the answer as to what exactly is likely to be proposed.Perhaps thats the idea to confuse everyone
Perhaps we should now and wait to see what they propose if they write it in understandable English that is
