Heathrow Airport Heathrow Airspace Modernisation (FASI South)

29/08/2023: The CAA has requested information by way of clarification relating to statements and assumptions made in the Change Sponsor’s Stage 2 submission. The Change Sponsor sought to amend its timeline to provide this information, as agreed to by the CAA. The Gateway will be re-scheduled shortly. We will publish the expected date of the Gateway as soon as a date has been confirmed.

30/10/2023: The CAA has completed the Develop and Assess Gateway Assessment and is not satisfied that the change sponsor has met the requirements of the Process up to this point. The CAA does not approve progress to the next Step. Further explanation for this decision is contained in the published document 'Develop & Assess Gateway Outcome - October 2023'.

13/12/2023: The revised airspace change process (CAP 1616, Version 5) will be implemented on 02 January 2024. This ACP does not currently have a date scheduled for its Stage 2 Gateway and can therefore continue to follow the CAP 1616 Version 4 process requirements for this Gateway until Stage 2 is completed. Once this ACP passes the Stage 2 Gateway, and is approved to proceed to the next stage, it will need to follow the process requirements as set out in CAP 1616 Version 5.

19/03/2024: Until iteration three of the airspace change masterplan, including the updated programme plan has been assessed and accepted by the CAA and Department for Transport as co sponsors of airspace modernisation, the full indicative timeline for this ACP cannot be confirmed. The Gateways within the published document 'Indicative Timeline - March 2024' are subject to change.

The CAA has determined that it will review Stage 2 Develop & Assess for ACP-2021-056 exceptionally at an additional Gateway on 14 June 2024.

This decision to review this ACP outside of the published schedule is due to a number of factors including but not limited to:

• the demand across the scheduled Gateways;

• the available CAA resource;

• the complexity of the proposal and the outstanding areas required to be addressed to meet CAP 1616 requirements;

• the resubmission of an unsuccessful previous Gateway whereby the CAA has had exposure to some of the details within;

• the sponsors’ ability to meet the alternative submission deadline.

It must be noted that this extraordinary Gateway is applied on a by-exception and case by case basis only at the discretion of the CAA.
