• The CAA has a dedicated portal for proposed changes to UK airspace being assessed against the CAP 1616 process. It provides communities and all interested stakeholders with a one-stop shop of information about designs of UK airspace that might impact them and an easy way to provide their views about changes. 

    The portal can be accessed here: https://airspacechange.caa.co.uk

    Changes can be located by searching for specific locations or by browsing each change being proposed by airports or other organisations (change sponsors).

    We will be removing access to our CAP 1616 airspace change proposal pages on this website over the coming weeks, as all content has been migrated over to the standalone airspace change portal. All airspace changes following CAP 725 process will remain on this website. 


    The airspace change process ensures that when the CAA decides whether or not to approve a proposal to change UK airspace, it does so in an impartial and evidence based way that takes proper account of the needs and interests of all affected stakeholders.

    The revised process introduces additional CAA scrutiny and validation of sponsors' work and evidence as they develop proposals; increased requirements relating to transparency and engagement; and introduced new opportunities for those impacted by proposals to have their voices heard.

    There are several different types of airspace change, with different CAA requirements depending on whether a proposal is for a permanent or temporary change. You can find out about the different categories of airspace change.

    Airspace changes vary greatly in terms of size and complexity, so the CAA has developed four Levels in which to categorise changes, depending on their potential impact. The change process is applied proportionately according to the Level of the change. You can find out about the different Levels of airspace change.

    During the airspace change process, a proposal must pass a series of gateways. We hold monthly Gateway Assessment meetings to review and sign off documentation showing that the criteria to proceed have been met. For a proposal to be considered at a Gateway Assessment meeting, the change sponsor must have submitted all of the relevant material to the CAA at least two weeks in advance of the meeting.

    Any aeronautical data associated with airspace change bound for the UK Aeronautical Information Publication (AIP) must be fit for purpose and in line with the necessary aeronautical data quality (ADQ) requirements as set out in EU Reg 73/2010 and further described in CAP 1054.

    The CAA Aeronautical Data Template is our preferred data exchange format and provides a vehicle for the data originator to submit and gain regulatory approval of AIP bound data and supporting metadata associated with CAP 1616 Airspace Design submissions in a consistent manner which is in line with the requirements of ADQ-IR. The scope of the data involved can be found in Annex A of CAP 1054. Please also read the Aeronautical Data Associated with Airspace Design (CAP 1616)
