Update - January 2022
The UK Civil Aviation Authority has launched a feedback exercise on its report setting out its draft findings into the Cotswold Region as part of our regional airspace classification review. The report sets out our findings on the airspace usage, including an overview of the different airspace authorities operating within the region, as well as the type and scale of aviation activity in the region. The report presents an overview of our evidence and recommendations, together with an initial plan of volumes to be taken to the amend stage of the procedure.
We are asking for feedback on our methodology used in deciding on the volumes proposed as part of our initial plan; as we want to make sure we haven’t misinterpreted any of the feedback received.
This information will be used to inform the airspace volumes we take forward to the amend stage of the procedure, as well as our approach to our other recommendations.

Update - August 2021
The UK Civil Aviation Authority's procedure to review the classification of airspace (CAP 1991) requires us to regularly consider whether to carry out a review of airspace classification; to carry out a review (including consulting airspace users) where we consider a change might be made; and to amend the classification as we consider appropriate.
We have decided to carry out our first review in the Cotswold Region and have produced a report which details what we know about airspace usage within the Cotswold Region, taking airspace composition, existing Airspace Change Proposals (ACPs) and safety data into account.
We invite stakeholders to review this report and to use it as background information to enable them to share their experiences of operating within this region through our online survey. This survey closes on 30th September 2021.
We have also produced a document answering some of the reoccurring questions asked by stakeholders in relation to the CAA’s Airspace Classification Review procedure. This particularly aims to assist those participating in this, our first review, of airspace in the Cotswold Region.

Update - April 2021
We have completed our detailed analysis of the consultation responses received from our call for suggested airspace for review, which was held between December 2019 and March 2020.
To support the information supplied in the consultation, additional data is required to enable us to move some proposals towards the Amend phase of the Airspace Classification Review process.
Read more details in this Airspace Classification update.
Update - January 2021
We identified 55 distinct airspace volumes from the consultation responses received in March last year. The review will identify those areas which have the potential of moving them to the Amend phase.
We have published more details in our January 2021 Airspace Classification update.
Update - December 2020
We will have a team in place early 2021 to deliver this work.
We have examined each of the proposed volumes to determine which could be taken forward to the “Amend” phase. In line with CAP1991 proposals were considered as suitable for this procedure where the following factors did not apply:
- Would the change have an adverse effect on military operations;
- Does the volume sit within airspace that is currently the subject of a change in airspace design through the CAP1616 Airspace Change Proposal (ACP) process;
- Does the volume sit within airspace that will be assessed by the CAA as part of the ACP post implementation review (PIR) process; or
- Does the proposal have a significant environmental or operational impact?
Effective December 2020, the CAA was given the function, by the Government, to review the classification of airspace and to amend them where appropriate. This function means that we must regularly consider whether to review the current classifications of airspace, consult airspace users as part of that review where we consider a change to classification might be made, and amend it ourselves in accordance with our classification review procedure.
We are also required to seek to ensure that the amount of controlled airspace is the minimum required to maintain a high standard of air safety and, subject to overriding national security or defence requirements, that the needs of all airspace users are reflected on an equitable basis.
What is airspace classification?
The Air Navigation Directions have long required the CAA to publish a national policy for the classification of airspace. ICAO requires that States determine those portions of airspace where air traffic services will be provided and, where it is so determined, whether air traffic control service or flight information service are provided. In turn, the airspace is designated according to the type of air traffic service provided and in accordance with the ICAO airspace classification system. Air traffic control service is provided to all flights within airspace classes A to D and to those flights operating in accordance with the instrument flight rules (IFR) in class E airspace; these are known as ‘controlled airspace’ classifications. Flight information service may be provided to all flights in class G (uncontrolled airspace) and to visual flight rules (VFR) flights in Class E airspace.
The procedure for reviewing airspace classification
The procedure is set out in CAP 1991 Procedure for the review of airspace classification and has three distinct stages:
- Consider, in which the CAA commits to carrying out a review of airspace classifications every two years, with the possibility to defer the review by up to one year.
- Review, in which we use appropriate intelligence, including continuous monitoring of airspace safety, access or utilisation issues, and data via our FCS1522 UK Airspace Access or Refusal of Air Traffic Services Report Form, to draw up a plan that lists airspace volumes where a case could be made for a proposed amendment to the classification, and a proposed schedule for when we will address them. We consult organisations in the Airspace Modernisation Strategy governance structure that represent airspace users in order to draw up a refined plan.
- Amend, in which, for each airspace volume identified, the CAA further develops a formal proposal for amending the classification, with essential input from the designated controlling authority for the airspace concerned, and then consults those impacted by the final proposals.
We are also providing a short summary of the procedure.
The procedure is completely separate from the airspace change process set out in CAP 1616.
Volumes of airspace to be reviewed in 2021
The first tranche of volumes of airspace that we will be looking to review in 2021 will be announced shortly. We will commence work on the first of these immediately with existing CAA resources, with our new dedicated team starting to arrive in January 2021.
All related documentation concerning this work will be published here, including:
- the status of the current review cycle (the stage, progress so far, proposed schedule)
- where the Review stage is in progress, details of any plan, draft or final, that lists airspace volumes where a case could be made for proposing an amendment to the classification (or for an alternative airspace management solution if this is a more proportionate response)
- where the Amend stage is in progress, details of any proposal for amending the classification that the CAA has made, and links to any public consultation (which will be accessed via the CAA’s consultation website)
- the CAA’s decision on any amendment
- the implementation arrangements for an amendment that has been approved by the CAA’s Airspace Regulation team
- a report by the CAA on the effectiveness of an amendment (or the alternative airspace management solution, as applicable), one year after implementation.
