caa logo CAA: Update on Daventry CTA 6 Airspace Amendment

After a comprehensive review, the UK Civil Aviation Authority is withdrawing its proposal to amend the base level of Daventry Control Area (CTA) 6 airspace due to safety concerns identified through analysis with NATS En-Route Plc (NERL). 

The CAA had proposed to raise the lower limit of Daventry CTA 6 by 2000 feet vertically from FL65 to FL85, in line with our findings that the base levels of Daventry CTA 6 appear to be used infrequently. The proposal did not include any changes to the amount of CAS above FL85.

By raising the lower limit of CTA 6 the base of this volume of airspace would then be aligned to the lower limit of the adjacent airspace volume: Daventry CTA 14. It was, therefore, further proposed that for simplification both areas be combined into a single block of airspace as the defining limits would have been identical for both CTAs (FL85 to FL195).
