Hi all,
I have come on here to find the answers to some questions controllers in Shannon High Level have for London controllers. I am doing it on pprune in order to cut out the middle (project) man, official line,ect ect. I am not looking for procedures to be established or rules laid down, just some opinions from London controllers!!
The big question today is about EGLL arrivals between 0400z and 0800z. Procedure says the traffic is restricted to fl 330 by Slany/Bakur/Evrin, with the use of FL310 and FL290 as required.
Recently after some sort of consultation with London about spacing between EGLL arrivals, a staff notice was issued stating that staff should endevour to provide "daylight" between the aircraft. This is brilliantly vague and is no help whatsoever.
At the moment, there are a few trains of thought on the matter:
1. Try our best to get 10+ miles between all EGLL and LTMA traffic, mostly using mach numbers.
2. Try to get some space between the arrivals, mostly less than 10 miles, but opening up with matching mach numbers.
3. Sod it, they are going to the hold anyway, just pile them in at different levels
4. Call london and ask for some aircraft to be sent to S9 on the Gibso or Merly track
I understand it is impractical and unfair to heavily restrict traffic west of 12W, which can make it difficult to get 10+ miles by STU, especially when faster (747, 777) are behind the slower aircraft (757,767,A30 ect).
If the London controllers could tell us what THEIR exit conditions are for LTMA arrivals on the east side of S8/S35 are then it might help us understand the best way to present the traffic. There is little point in working hard to provide 15nm in trail if London only need 10nm on handover to the next sector!
Some of the Shannon controllers are reluctant to ask what way London controllers would like the traffic presented to them, for reasons unknown to me...
Any suggestions?
