In February 2018, the CAA published further information for stakeholders in the TANS sector (CAP 1633), following the SDG review of transitions.

In February 2017, we published the results of Steer Davies Gleave's reviews of the TANS transitions at Birmingham and Gatwick airports. The reviews found that that no issues had emerged so far in terms of the continuity or quality of service, but identified a number of challenges that had emerged between the incoming and outgoing providers. The reports contained a number of recommendations to the CAA and other stakeholders to help facilitate future transitions. Andrew Haines (the CAA's Chief Executive) wrote to stakeholders advising them of the main recommendations.

In October 2016, the European Commission published its decision that the market for terminal air navigation services in the UK is contestable (no. 2016/1940). The decision applies until 31 December 2019.

In December 2015, the CAA's Chief Executive advised stakeholders that he expected airports and TANS providers to respond positively to the expected decision by the European Commission that the market conditions exist in the UK for the provision of terminal air navigation services.
