• Regulation 2017/373, the “Air Traffic Management (ATM) / Air Navigation Services (ANS) Implementing Regulation” (ATM/ANS IR) took effect in law on 2 January 2020. The Regulation lays down common requirements for providers of ATM and ANS and other air traffic management network functions and their oversight and replaced Implementing Regulations (EU) 1034/2011, 1035/2011 and 482/2008.

    The ATM/ANS IR is based on ATM-related ICAO Standards, Recommended Practices (SARPs) and Procedures for Air Navigation Services (PANS).

  • Effective date

    With the exception of Annex VII (Part-DAT), which takes effect on 1 January 2019, Regulation 2017/373 takes effect on 2 January 2020. Parts AIS, ATS and FPD remain under development  and effective dates for each have yet to be proposed.

    UK regulatory changes

    Consideration will be given to amending the Air Navigation Order 2016 and/or the Single European Sky (national Supervisory Authority) Regulations 2013 in order to designate the CAA as the UK’s competent authority for the ATM IR.  Development of Part-ATS will generate amendments to the Standardised European Rules of the Air, which may in turn require amendment of The Rules of the Air Regulations 2015 and/or the permissions and general exemptions that support both.  The need for further UK legislative change has yet to be identified.

    The CAA publishes a consolidation of the Air Navigation Order, the Rules of the Air regulations and other legislation in CAP393 Air Navigation: The Order and Regulations

    In terms of non-legislative ATM regulatory material, it will be necessary for the CAA to review its ATM-related CAPs and amend these to reflect the ATM IR’s requirements.

    Industry engagement

    Initial engagement with industry regarding CAA implementation plans has been through its ATM IR Implementation Consultative Group. Various additional means of engagement are being identified and communications will be developed accordingly. These are expected to include NATMAC, GA Partnership, FASIIG, FASVIG, representative organisations or any combination of these. Focused consultation with interested stakeholders may be considered, as will more general public consultations.

    The ATM IR presents opportunities to evolve UK ATM arrangements on a sustainable basis; it also presents a number of challenges.  In moving forward we would wish to do so in close collaboration with industry.

    ATM IR Implementation Consultative Group

    The purpose of this focus group is to:

    • Create mutual CAA/industry awareness and understanding of the changes to requirements and the impacts of these resulting from the implementation of the ATM IR in the UK
    • Provide a forum for discussion and informal consultation on changes required by ATM IR implementation to ensure those changes are proportionate and appropriate to the risk posed, and costs are identified and minimised
    • Remain transparent to be open and keep regulations simple and user-friendly
    • Industry embers to represent their sector of the industry and to act as a liaison between the CAA and those whom they represent.

    The group's membership can be expected to evolve according to implementation activities and priorities.

    Relevant news

    The CAA will update its ATM IR web pages to reflect progress with both the rule’s development and the UK’s implementation of it. Industry will be notified of any such changes by means of ‘Skywise’ alerts (skywise.caa.co.uk)

    EU Exit

    At 23:00 on 31 December 2020 the UK left the European Union aviation system and as such is no longer part of European Union aviation institutions, including the European Union Aviation Safety Agency (EASA).

    We have published the law that now applies (i.e. those laws as retained (and amended in UK domestic law) under the European Union (Withdrawal) Act 2018) on a dedicated UK Regulations section of the CAA website.

    This includes UK Regulation (EU) 2017/373 ‘The ATM/ANS IR’ and its associated acceptable means of compliance (AMC) and guidance material (GM).


    Future Amendments

    Regulation (EU) 2020/469 which amends Regulation (EU) 2017/373 is due to become applicable in European law on 27 January 2022.  The CAA plans to initiate a rulemaking task in due course to consider the adoption of Regulation (EU) 2020/469 into UK law.
