Dutch ELT
I have just spoken to 'the man who knows' at the ATC Netherlands AIS, Schipol regarding ELT/PLB in Dutch airspace.
He confirmed that for non-AOC flights a PLB is sufficient.
NOTE that he defined PLB as a PORTABLE Locator Beacon correctly registered as an approved device with the UK authorities (eg UK ELT Database, UKMCC, ARCC, RAF Kinloss) and NOT a Personal Loc Bcn 'as used by hill walkers' etc.
