UK – EU Transition, and UK Civil Aviation Regulations

The Department for Transport and CAA are co-sponsors of airspace modernisation. In 2018, we commissioned NATS (En Route) plc (NERL) to create a single coordinated implementation plan for airspace changes in the UK, known as the airspace change masterplan (or masterplan). Given the large number of parties involved in the development of the masterplan, including many airports and NERL itself, the co-sponsors required NERL to set up a separate and impartial unit, the Airspace Change Organising Group (ACOG), to develop the masterplan (as required by condition 10a of NERL’s Air Traffic Services Licence).

Further information about ACOG such as details on the members of its Steering Committee or ACOG’s stakeholder engagement activity, please visit ACOG's website.
