Reduction inside 4 miles is a huge problem. At some units the tower needs to take this into consideration as radar only provides the 'gap' to 4 miles and this is published in pt2.
The problem for them (The folk in the VCR) is that crew can fly the same plane differently, the plane may well be empty, there could be training on the flight deck, the weather may play a part as well.
Good point HD, a miss read thread?
So what is the problem at Heathrow, you have two runways and falling traffic!
Joke over, although a good debate though!
Bye the way, the post actually says final approach speed and no ref to 4 miles or inside, was that the reason for the Orson post?
