Parliament and the Government are responsible for setting the CAA’s statutory objectives, outlining our functions and responsibilities, and providing guidance to us.
During Stage 5 of the CAP 1616 airspace change process, under certain circumstances, the Secretary of State may decide to 'call-in’ an airspace change proposal.
If the Secretary of State takes the decision to call-in an airspace change proposal, the Secretary of State becomes the decision maker, instead of the CAA.
The Secretary of State must be satisfied that one of three call-in criteria apply. These criteria are that the proposed change:
- is of strategic national importance or,
- could have a significant impact (positive or negative) on economic growth of the United Kingdom, or
- could both lead to a change in noise distribution resulting in a 10,000 net increase in the number of people subjected to a noise level of at least 54 dB LAeq 16hr and have an identified adverse impact on health and quality of life.
When we receive a call-in request, we will provide an assessment to the Secretary of State as to whether the proposal meets one or more of these call-in criteria. The Secretary of State has provided the CAA with guidance on the meaning of these criteria.
The Secretary of State may not determine that the proposal will be decided by them if the proposed change is:
- submitted by, or on behalf of, the Ministry of Defence, or
- directly related to a planning decision which had already been determined by the Secretary of State or another planning authority which involved detailed consideration of changes to flight paths in UK airspace, consequential on the proposed development, which the sponsor has taken into account when developing its proposal.
Who can make a call-in request
Anyone can ask the Secretary of State to call-in an airspace change proposal, but even if an airspace change proposal meets the criteria, there is no obligation on the Secretary of State to agree to call-in the proposal.
Submitting a call-in request
Where an airspace change is being considered under the previous CAP 725 process
A call-in request should be submitted in writing within four weeks of the CAA indicating on its website the date that the change sponsor’s formal airspace change proposal has been received by the CAA. The request should be emailed to: airspace.regulation@caa.co.uk
Where an airspace change is being considered under the current CAP 1616 process
A call-in request should be submitted via the Airspace Change Portal within four weeks of the CAA indicating on the portal the date that the change sponsor’s formal airspace change proposal has been received by the CAA.
In either case, requests made outside of that four-week window will not be considered.
In response to the request, the call-in criteria are assessed to determine whether the proposal is eligible to be called-in. The Secretary of State will decide whether the proposal is eligible to be called-in and whether it will be called in. The Secretary of State aims to do so within eight weeks of the proposal being submitted.
