Deep and fast,
Yes I use the 3nm per 1000ft as well.We really only have a problem with EMB145/135,and it is noticeable that they leave their descent very late.The other problem is that from certain headings,giving extended routing make it difficult to get them on the localiser.They are still at 240kts,so the radius of turn is large.It is better to give an orbit,or take them out of the sequence,both of which add a lot more miles and cost fuel.I also do not like trying to give a gap to Tower,having it eaten away with a/c boring down the ILS at 240 kts.
The other day I vectored 8 EMB145 during the course of one afternoon/evening.5 of them were too high.
I agree that it is time to put this to bed.However I won't be giving dog legs through final anymore.They will be re-positioned properly off the hold,or put to the back of the sequence.
