The IAA is currently undertaking a review of Irish Airspace - some vague details are available in AIC 002/2021
. Comments are open from pilots until 23rd April to email@example.com
. It's really important that you get your comments to this address asap. I get the feeling, and there are rumours, that controlled airspace will be lowered to 4,500ft across the entire FIR. There is also huge scope to reduce the footprint of Control Zones and open up airspace where it has never been needed in the past.
