What is separation
One mile between aircraft when visual separation does not apply (ignoring the vertical plane and wake turbulance)...
Radar, procedural, 'deemed' etc, is all about proving the minimum separation standard exists; that is one mile, laterally, and longitudinally...
All the standards used have a buffer or tollerance built in; but essentially they all achieve the same standard, which is one mile separation.

One of my favorites over here that I haven't seen mentioned is diverging courses... We got to use that here in the approach control facilities where they are using a single site radar... You get two aircraft that are diverging by at least 15 degrees and you get target resolution (there is space between the two radar targets <we call it green between>.) and we can then discontinue vertical separation, so you can see someone a half mile off your wing come blasting through your altitudes as they pry away from you <G>...
Wish we could use that enroute <sigh>...

Spitoon and 5miles baby
Jesus you two lighten up if people actually read what was posted and not what they think they have read perhaps these forums would be put to better use, instead of just a chat room for the self important and self opinionated

So here is a question for all you ATCO's out there. What is the separation between an a/c flying in class a airspace working area control whose standard separation is 5 miles and an a/c working approach control in class d airspace which ajoins the class a airspace but its minimum separation is 3 miles. Is the separation between adjoining airspace 3 or 5 miles?

Without knowing the exact details of your unit...
I seem to remember that the ability to use 3 miles separation required details already highlighted, such as distance from radar head and so on, but also:
Both aircraft under the control of one controller or co-located controllers where direct coordination was possible (or some-such MATS-speak).
In the case you mention, these criteria would not seem to apply, so 5 miles required. Which makes sense, using the worst case is better than hoping for the best!

ILS 119.5
Radar separation is normaly 5 NM, can be more, depends on national regulations. It can be reduced to 3 NM as well and to 2,5 NM on the final approach but within 10 NM only. Radar separation from the next sector is normaly half of radar separation of that one you apply, it is valid also for the next sector to apply the same rule and you are radar separated.
I hope it helps,
