New drone regulation has been introduced here in Ireland. How it will be policed, I don't know? https://www.iaa.ie/news/2015/12/17/drone-registration-to-commence-on-21st-december-2015
I saw that this morning. Sub 1kg pretty much includes everything, bar maybe little FPV racers and some fixed wing foamies. Do you think they're in cahoots with the FAA?
From what I have read in the papers regarding to enforcement, the Gardai(Irish Police) are insisting it is up to the Irish Aviation authority to police the drive with the assistance of the other/or whoever. Here's the good news for them is that owners of unregistered UAV's could be fined up to €27,000, nice little lousy money spinner.
They might find it causes them more of an administration headache than it's worth, which may also be the case in America? Have to wait and see I guess.
