3nm ???? Normally turn for a 1.5nm final in GIB, 1nm for the northerly runway in Figari, similar in a couple of the Greek islands that I've been to.
You let us, we can. Chances of letting us... Errm, probably small!
But the one I did do to 09L ended up on a 4nm final (sorry so slack, but we did have the gear out to get down!) Director was still cheeky enough to vector someone 3nm behind us - Took us by surprise when we noticed!
