Official Journal EN of the European Union L series 2025/2143 24.10.2025 COMMISSION IMPLEMENTING REGULATION(EU) 2025/2143 of 23 October 2025 amending Regulation (EU) 2015/340 as regards the introduction of competency-based training and assessment and virtual training of air traffic controllers THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EU) 2018/1139 of the European Parliament and of the Council of 4 July 2018 on common rules in the field of civil aviation and establishing a European Union Aviation Safety Agency, and amending Regulations
(EC) No 2111/2005, (EC) No 1008/2008, (EU) No 996/2010, (EU) No 376/2014 and Directives 2014/30/EU and 2014/53/EU of the European Parliament and of the Council, and repealing Regulations (EC) No 552/2004 and (EC) No 216/2008 of the European Parliament and of the Council and Council Regulation (EEC) No 3922/91(1), and in particular Article 50(1), points (b) and (c), and Article 53(1) thereof,
Whereas:
(1) Commission Regulation (EU) 2015/340(2) lays down the technical requirements and administrative procedures relating to air traffic controllers’ licences and certificates.
(2) The limited flexibility and availability of air traffic controller resources in the Union restrict the capacity of the European Air Traffic Management (‘ATM’) system. Therefore, adaptations to the regulatory framework concerning the licensing and qualification of air traffic controllers are needed.
(3) To better cater for the needs of air navigation service providers in terms of qualified and available personnel, the required level of competence set out in Regulation (EU) 2015/340 should be further streamlined to ensure that the applied training methodology and syllabi ensure a common training output and thus positively contribute to the operational needs.
(4) To enable a streamlined training output, the regulatory framework for air traffic controller training in the Union should be enhanced by setting out the required performance standards applying the principles of competency-based training and assessment (‘CBTA’), which is also the International Civil Aviation Organization (ICAO) preferred route to all aviation personnel licensing.
(5) To better contribute to the application of the CBTA methodology for air traffic controllers’ training, the CBTA methodology should be established setting out the performance standards to be met by instructors and assessors, by applying the same CBTA principles.
(6) Following the experience gained during the COVID-19 pandemic, enabling the virtualisation of training for air traffic controllers could be beneficial. With virtual training, geographical separation of students, instructors and assessors should not pose a limitation to the facilitation of air traffic controller training.
(7) To enable air traffic services providers and air traffic controller training organisations to adapt, respectively, their unit competence schemes and their training plans and training courses, the date of application of this Regulation should be deferred.

(2) Commission Regulation (EU) 2015/340 of 20 February 2015 laying down technical requirements and administrative procedures relating to air traffic controllers’ licences and certificates pursuant to Regulation (EC) No 216/2008 of the European Parliament and of the Council, amending Commission Implementing Regulation (EU) No 923/2012 and repealing Commission Regulation (EU) No 805/2011 (OJ L 63, 6.3.2015, p. 1, ELI: http://data.europa.eu/eli/reg/2015/340/oj).
ELI: http://data.europa.eu/eli/reg_impl/2025/2143/oj 1/21EN OJ L, 24.10.2025
(8) To avoid discontinuity in the training process, certificates of completion of certain courses that started prior to the date of application of this Regulation should be accepted for the purpose of the issue, revalidation or renewal of the relevant licences, ratings and endorsements, provided that the training and the assessment have been completed by 30 June 2029.
(9) Regulation (EU) 2015/340 should therefore be amended accordingly.
