Some assumptions on this thread are worrying.
Porco Rosso,
Just as an aside they've changed the rules for 2.5nm spacing and we're now going to be able to do it much more often than we have in the past.
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.
120.4, anytime you want to refuse doing 2.5 is fine by me!!!
411A, you're coming down the ILS at 160 to 4 in your lovely old L1011, as instructed, with a medium 5 miles behind you, and an A320 now about 2.5 miles in front of you which has just reduced back to 120kts at 6 miles rather than 4 without telling us. Please tell us all how we can 'accomodate' that to your satisfaction
