This page contains details about all airspace change proposals being developed under the CAA's
revised airspace change process, introduced on January 2018. You can find airspace change proposals being developed under the previous process
on this page.
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.

Level 1 changes impact on aircraft operating below 7,000 ft and are therefore most likely to affect noise experienced by people on the ground.
Airspace change proposals in all four Levels can be found under the name of their Sponsor below.
Some airspace change proposals are still being developed under the old airspace change process, and are not contained on this part of the website. These are developed and assessed in a different way, and can be found
