Revision of Special Visual Flight Rules (SVFR) Weather Minima Criteria for Operations Within the London & London City CTRs

We are conducting a review of the weather minima applied to operations under Special Visual Flight Rules (SVFR) within the London Control Zone and the London City Control Zone (the London CTRs).

Since 2013 a number of questions have been raised regarding the suitability of the existing weather minima to maintain the high standard of aviation safety in this operating environment. Work undertaken has identified a number of areas of concern, including the changing urban landscape and proliferation of tall buildings, changing traffic density and traffic mix, the introduction of drones and the plans for Advanced Air Mobility (AAM), for example.

The CAA proposes a change to the SVFR weather minima and the purpose of this engagement period is to seek views, opinions and feedback from the stakeholder community.
