Clearances 2
'There seems to be some confusion over the continued validity of a restriction when passed to another controler who doesn't confirm or repeat that restriction. As I understand it the limit must be re stated otherwise it no longer applies. For example, London will clear descent to be FL 200 10 mls before Strumble say, before reaching this one is handed over to Man who pass a lower clearance at Strumble but don't re iterate the 200 at 10 before, is one correct in assuming that it no longer applies?'
I was hoping for a definitive reply from the ATC guys. It would seem though that the issue is contentious. This surely is a potentially critical issue, anyone got the 'chapter and verse'?
