What people in the UK should remember when they point the finger at Swiss ATC is that London controllers routenely accept aircraft from France northbound at the same level as westbound aircraft when both aircraft will cross Brookmans Park (BPK) beacon at the same time. They do this in "the anticipation" that they can change the level or vector the aircraft at a later time......Does this sound familiar?
Furthermore, the single computer that supplies data to the 4 UK atc centres and the busiest airports is switched off about once per week and when this single computer is off or as in recent cases has failed then the conflict alert system is not available to controllers.
Perhaps a UK ATC person could comment on the above.
