PPRuNe Radar,
The problem is that he is ignoring the UK AIP
That is exactly my point.........when is it OK for ATC to ignore the AIP and not for the pilot to do the same?
You are quite correct, radio equipped aircraft are required to inform ATS of changes to a flight plan to avoid unnecessary alerting action. That is why radio equipped aircraft are treated differently to non-radio in the MATS 1.
Put yourself in somewhere like Alaska with the UK AIP and ATS system. Would you treat flight plans in the same way?........ignoring flights wo depart but don't turn up?
Regards,
DFC
