CAAIn addition to some revised base and upper levels, the new airways also include extra airspace in the vicinity of the Aberdeen CTRCTA.

The Civil Aviation Authority (CAA) has announced that the UK’s Class F airspace is to change. This follows the recommendations of an ICAO audit, changes to European legislation under the Single European Rules of the Air and a subsequent review of national airspace arrangements, which included a consultation with the aviation community.

Class F airspace has been established for many years in the UK Flight Information Regions (FIR) in the form of Advisory Routes (ADRs). These ADRs will be replaced either by Class E ‘airways’, which will be designated as Transponder Mandatory Zones (TMZs), or returned to Class G airspace. However, the dimensions of the new Class E airways will not necessarily mirror the exact dimensions of the ADRs they replace, the CAA pointed out. In addition to some revised base and upper levels, the new airways also include extra airspace in the vicinity of the Aberdeen CTR/CTA.
