all foreign non-EASA aircraft (Annex II, homebuilts, microlights etc) from Dutch airspace.
Isn't the key in the wording, FOREIGN? Doesn't our CAA already do this - you don't see many N reg RV6's flying around the UK do you.
I am guessing that an N reg RV6 re-registered on the G or Dutch register or an RV6 built in the UK or Holland would be ok.
