GENERAL

(a)Point (5) of Article 3 of Regulation (EU) 2018/1139 defines ATM/ANS as ‘the air traffic management functions and services as defined in point 10 of Article 2 of Regulation (EC) No 549/2004; the air navigation services defined in point 4 of Article 2 of that Regulation, including the network management functions and services referred to in Article 6 of Regulation (EC) No 551/2004, as well as services which augment signals emitted by satellites of core constellations of GNSS for the purpose of air navigation; flight procedures design; and services consisting in the origination and processing of data and formatting and delivering data to general air traffic for the purpose of air navigation’.

(b)It should, therefore, be noted that ‘ATM/ANS’ includes more services and functions than ‘air traffic management’ and ‘air navigation services’ together.

(c)It is important to note that ATS is included in ATM and ANS.

(d)As already defined, ‘ATM network functions’ refers to functions performed by the Network Manager in accordance with Regulation (EU) 2019/123.
