We initiated a review of the CAP1616 Airspace Change process in 2021, three years after its implementation and an updated version was implemented on 2 January 2024. The new version addresses key feedback themes identified through the review and focuses on providing simplification, clarification and proportionality. For more detailed information on the improvements that have been made, please see our Airspace Change Process page. 

For further information on transition arrangements, please see the CAP1616 review webpage.

A prime objective of the CAP1616 Airspace Change process is that it is as transparent as possible throughout and the CAA runs the Airspace Change Portal that holds all relevant information on individual airspace change proposals, including consultation responses. The Portal has been designed to provide communities and all interested stakeholders with a single source of information about designs of UK airspace that might impact them and an easy way to provide their views about changes.

The Airspace Change Portal is the primary source of information on all CAP1616 airspace change proposals and should be used to access more information about the airspace change process. The Portal’s About Airspace Change section details the:

  • types of airspace change
  • levels of airspace change
  • seven stage process for permanent changes to the notified airspace design
  • process for temporary changes to the notified airspace design and airspace trials
  • Planned and Permanent Redistribution of Air Traffic (permanent and temporary).

The Portal also explains how stakeholders can have their say and the steps in the process at which stakeholder feedback is sought. This information is also detailed in CAP1616 Airspace Change.
