Not sure what you guys have been told, but this is certainly not the case. The rules have been changed so as to, in effect, 'legalise' the situations where FIN has aimed for 3 and got anywhere between 2.5 and 3. The inbound spacing to LL will still be 3 miles, whereas separation can now legally be anything down to 2.5 miles. The rules on when we adopt 2.5 miles spacing have not changed.
Gonzo, this has been sold to us as a change in procedure partly to tie up with what actually happens in practice but also to increase the envelope when 2.5nm can be used.

Take a look at the opening paragraph of our SI if you can get hold of it.

As for the tail wagging the dog. I don't try and do 2.5nm, or even 3nm spacing, for fun. I do it because that is what is required to to keep the airlines happy at a capacity constrained airport.

If one part of the airline industry is demanding maximum landing rate every hour of the day and another part of the same industry is saying we can't fly the required profile then the airlines need to sit down and agree exactly what is acceptable to them and what isn't then tell us in a co-ordinated fashion.
