Airspace4All has carried out an audit of the extant CTR/CTA airspace in the UK, along with all associated SID/STAR routing. Using a baseline of the commercial air traffic containment principles (ICAO) employed elsewhere in Europe, Airspace4All will produce a detailed statistical report on how the volumes of terminal airspace in the UK could be designed more efficiently.

However, mindful of the ongoing development of the CAA’s Airspace Modernisation Strategy and the potential future needs of Part-ATS, Airspace4All will aim to balance the results of this audit against other commercial airspace design initiatives (including FASI-N and FASI-S) to help inform the many Airspace Change Proposals currently in the pipeline.
