London Southend Airport (LSA) is a stakeholder in the development of the wider UK Airspace Modernisation Strategy that is sponsored by the Department for Transport and has been developed by the CAA. Please read more information.

This will see a once in a lifetime opportunity to modernise airspace, in particular in the SE region of the UK, that has not had any significant changes for the last 50 years. LSA have filed an Airspace Change Proposal (ACP) to support this strategy. LSA has appointed Cyrrus to support us with the development of the ACP.

Learn more about LSA’s progress with this ACP.

Following the original submission of the Stage 2a and 2b documentation for the January 23 Gateway, the CAA were not satisfied that the change sponsor (LSA) had met the requirements of the Process. The CAA did not approve progress to the next Step. Further explanation for the decision is contained in the published document: Develop & Assess Gateway Outcome – January 2023.

LSA have worked on addressing the comments raised by the CAA and resubmitted the documentation for the December 23 gateway. LSA were informed on Friday 15th December that the CAA were not satisfied that the change sponsor had met the requirements of the process and LSA are not approved to move forward with the ACP. A link to LSA’s progress with this ACP can be found here (Airspace change proposal public view (

LSA will advise on next steps in the new year once all of the feedback has been fully digested.

Once LSA has successfully passed through the gateway (a decision is expected in December 23), work will begin on Stage 3 ‘Consult’. There are 4 parts to Stage 3:

  1. Stage 3A: Consultation Preparation
  2. Stage 3B: Consultation Approval > Gateway
  3. Stage 3C: Commence Consultation
  4. Stage 3D: Collate and Review Responses

Further information is available here on the CAP1616 process that LSA is required to follow.

More information will be published on this webpage when available.
