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^note and in particular Article 44(1)(a) thereof,Whereas:

(1)Commission Implementing Regulation (EU) 2018/1048^note lays down airspace usage requirements and operating procedures concerning performance-based navigation (PBN).

(2)Implementing Regulation (EU) 2018/1048 requires the implementation of air traffic services (ATS) routes in accordance with the requirements of the area navigation (RNAV) 5 specification for all single European sky (SES) en route operations.

(3)The RNAV 5 specification was developed to support operations in continental airspace. The specification requirements for the loss of the aircraft’s navigation function are not compatible with operations in oceanic or remote continental en route airspace, so the use of such specification could result in potential safety regression.

(4)Both RNAV 10 and required navigation performance (RNP) 4 are navigation specifications that were specifically designed by the International Civil Aviation Organization (ICAO) to support en route operations in oceanic and remote continental airspace, which is also part of the SES. Therefore, they can ensure consistency between the aircraft performance requirements (the PBN specification) and the navigational performance required for such operations.

(5)The use of the RNAV 10 or RNP 4 specifications in oceanic and remote continental airspace ensures harmonised ATS route implementation.

(6)Use of the radius to fix (RF) functionality and/or altitude constraints together with RNP 1 standard instrument departure (SID) and standard instrument arrival (STAR) routes should be subject to local needs.

(7)Commission Implementing Regulation (EU) 2021/2237^note introduced the new ICAO approach classification, which no longer differentiates between CAT IIIA and CAT IIIB operations; alignment with the current definition of CAT III operations in EU legislation is deemed necessary.

(8)Implementing Regulation (EU) 2018/1048 should therefore be amended accordingly.

(9)The European Union Aviation Safety Agency has proposed measures in its Opinion No 03/2024^note in accordance with Article 76(1) of Regulation (EU) 2018/1139.

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