Summary
The last iteration to be accepted into the CAA’s Airspace Modernisation Strategy (AMS) was Iteration 2 in January 2022.
Since then, we have accepted Airspace Change Organising Group (ACOG)’s proposed ‘clustering’ approach to master plan development, grouping proposals geographically.
Following a public engagement exercise, ACOG expect to submit an Iteration 3 covering the Scottish cluster for assessment in early 2024. This will be followed by the remaining clusters in due course.
Next steps
Prior to the submission of Iteration 3, ACOG is required to run a public engagement exercise to gather the views of individual stakeholders on the development of the master plan at a strategic level. This engagement exercise supplements the CAP 1616 consultations for each airspace change proposal.
More information about ACOG’s engagement can be found on acog.aero. ACOG also distribute a quarterly newsletter which you can sign up to here.
