         COMMISSION IMPLEMENTING REGULATION (EU) 2020/469
         of 14 February 2020
         amending Regulation (EU) No 923/2012, Regulation (EU) No 139/2014 and Regulation (EU) 2017/373 as regards requirements for air traffic management/air navigation services, design of airspace structures and data quality, runway safety and repealing Regulation (EC) No 73/2010
         (Text with EEA relevance)
         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 points (c) and (g) of Article 36(1), points (a) and (f) of Article 43(1) and Article 44(1) thereof,
         Whereas:

                     (1)

                     Commission Regulation (EU) No 923/2012 (2) lays down the common rules of the air and operational provisions regarding services and procedures in air navigation applicable to general air traffic (the so called ‘rules of the air’).

                     (2)

                     Commission Regulation (EU) No 139/2014 (3) lays down requirements and administrative procedures related to aerodromes, including their management, operation, certification and oversight.

                     (3)

                     Commission Regulation (EU) 2017/373 (4) lays down common requirements for providers of air traffic management/air navigation services (‘ATM/ANS’) and other air traffic management network functions (‘ATM network functions’) for general air traffic and their oversight.

                     (4)

                     In order to ensure a high level of civil aviation safety in the Union, flight crews should be required to report to the air traffic service units, when the runway braking action they encounter is not as good as reported to them. Those reporting obligations should be set out in Implementing Regulation (EU) No 923/2012.

                     (5)

                     On 31 March 2016 the International Civil Aviation Organisation (‘the ICAO’) adopted Amendment 77-A to Annex 3 to the Convention on International Civil Aviation, signed on 7 December 1944 in Chicago (the ‘Chicago Convention’) aiming at improving the provision of information on hazardous meteorological conditions, enhancing situational awareness and contributing to a more efficient routing, including circumvention of hazardous meteorological conditions. That amendment is applicable in ICAO Contracting States as of 10 November 2016 and it should be reflected in Regulation (EU) 2017/373, in particular in the provisions on meteorological services (Annex V – Part-MET).

                     (6)

                     Regulation (EU) 2017/373 should reflect the state of the art in aviation safety, as well as best practices and scientific and technical progress in aeronautical information services (‘AIS’). Therefore, amendments to Regulation (EU) 2017/373 should be based on the applicable ICAO Standards and recommended practices (‘SARPs’), in particular on the Sixteenth Edition of Annex 15 ‘Aeronautical Information Services’ to the Chicago Convention, while drawing on the experience of the Union in AIS provision and ensuring proportionality according to the size, type and complexity of the AIS provider (‘AISP’).

                     (7)

                     On 31 March 2016 ICAO adopted also Amendment 77-B to Annex 3 to the Chicago Convention which aims at reducing runway excursion incidents and accidents. That Amendment 77-B to Annex 3 will be applicable in the ICAO Contracting States as of 5 November 2020. That amendment should also be reflected in Regulation (EU) 2017/373, in particular in the requirements laid down in Annex V as regards the provision of meteorological services and in Annex VI as regards the provision of aeronautical information services.

                     (8)

                     Pilots should be informed through notices to airmen when a runway is temporarily unavailable due to marking works. In order to increase runway safety, pilots intending to operate on a specially prepared winter runway or on a slippery wet runway should be appropriately informed. The dissemination of friction measurements to pilots should not be allowed because friction measurements are not correlated with aeroplane performance.

                     (9)

                     Common technical rules for the design of airspace structures as well as common requirements for service providers of flight procedure design (‘FPD’) should be established in Regulation (EU) 2017/373 to ensure that the airspace structures and flight procedures are properly designed, surveyed and validated before they can be deployed and used by aircraft.

                     (10)

                     Flight procedures and any changes thereto can affect the safety of flight operations at the aerodrome. Consequently, a clear link between the existing Regulation (EU) No 139/2014 and Regulation (EU) 2017/373 should be introduced.

                     (11)

                     With the adoption of the Seventh Edition of Annex 10 to the Chicago Convention on ‘Aeronautical Telecommunications’ (Volume II) published in July 2016, the Fifteenth Edition of Annex 11 to the Chicago Convention on ‘Air Traffic Services’ and the Sixteenth Edition of Doc 4444 ‘Procedures for Air Navigation Services – Air Traffic Management (PANS ATM)’, the ICAO adopted new ICAO SARPs on aviation safety in the provision of air traffic services (‘ATS’).

                     (12)

                     For those reasons, and in order to ensure the uniform implementation and compliance with the essential requirements set out in point 2.3 of Annex VIII to Regulation (EU) 2018/1139, Regulation (EU) 2017/373 should be amended accordingly.

                     (13)

                     Regulation (EU) No 923/2012 and Regulation (EU) 2017/373 should also include detailed provisions with regard to the availability and the conditions for the use of the Very-high frequency (VHF) emergency channel.

                     (14)

                     Additionally, taking into account the impact of ATM/ANS on pilot actions and aerodrome operations, those new measures should also be reflected in the relevant provisions of Regulation (EU) No 923/2012.

                     (15)

                     Those new measures include also detailed provisions on the quality of aeronautical data and aeronautical information and therefore Regulation (EU) No 73/2010 (5) should be repealed.

                     (16)

                     The industry and the competent authorities of the Мember States should be given sufficient time to adapt to the measures introduced by this Regulation.

                     (17)

                     The measures provided for in this Regulation are based on Opinion, 02/2018, Opinion 03/2018 and Opinion 03/2019 of the European Union Aviation Safety Agency in accordance with point (b) and (c) of Article 75(2) and Article 76(1) of Regulation (EU) 2018/1139.

                     (18)

                     The measures provided for in this Regulation are in accordance with the opinion of the committee established by Article 127 of Regulation (EU) 2018/1139.

                                                                  obstacle data;

                                                                  geographical position data.

                                                      (b)

                                                      The tables of the aeronautical data catalogue are composed of the following columns:

                                                                  (1)

                                                                  (9)

                                                                  origination type: data is identified as surveyed, calculated or declared;

                                                                  (10)

                                                                  publication resolution;

                                                                  (11)

                                             Note for items 2 and 3 under point (b): the classification of a catalogue element as subject, property or sub-property does not impose a certain data model.

                                             Note for item 7 under point (b): for those fixes and points that serve a dual purpose, e.g. holding point and missed approach point, the higher accuracy applies. Accuracy requirements for obstacle and terrain data are based on a 90 % confidence level.

                                             Note for item 10 under point (b): the publication resolutions for geographical position data (latitude and longitude) are applicable to coordinates formatted in degrees, minutes, seconds. When a different format is used (such as degrees with decimals for digital data sets) or when the location is significantly further to the north/south, the publication resolution needs to be commensurate with the accuracy requirements.
