ATS Requirements Overview

The purpose of these pages is to provide a convenient reference point for service providers and operators of various aeronautical radio stations in respect of the major regulatory requirements and associated documents.

The following links on this page provide references to various sources of requirements and CAPs relevant to each type of service and aeronautical radio station.


The complexity of the various regulatory requirements and Institutional Arrangements is depicted in Figure 1.

NOTE: The European ATM Regulatory Framework is subject to considerable development, but under which SES and EASA high-level Regulations co-exist.  EASA ATM Regulations now consist of Implementing Rules developed under the Basic EASA Regulations 216/2008 (as amended by Regulation 1108/2009, but which are still subject to elements of the SES high-level Regulations, in particular the Service Provision Regulation (Regulation 550/2004). In due course it is expected that the relevant parts of these SES Regulations will be amended to bring them into line with the Basic EASA Regulation.
In view of the time scales involved in updating various types of promulgated material, references in these web pages to EU Level Regulations may not be up to date and it is advised that readers take note of any information promulgated via means such as CAP Amendments, CAA Information Notices and website information.

The following three EASA ATM Implementing Rules are relevant to ATM/ANS:

  • Commission Regulation  (EU) No. 805/2011 on ATCO Licences (in force from 31 August 2011);
  • Commission Regulation (EU) No 1034/2011 on safety oversight in ATM and ANS (in force from 7 November 2011);
  • Commission Regulation (EU) No 1035/2011 on common requirements for ANS provision (in force from 7 November 2011). 

The former ATCO Directive (2006/23/EC), now replaced by the ATCO Regulation above, was repealed by the amended Basic EASA Regulation (Regulation (EC) No 1108/2009.  The new Common Requirements and Safety Oversight Regulations respectively repealed their SES equivalents, Regulation (EC) 2096/2005 and Regulation (EC) 1315/2007.  It is expected that now that these subjects are within the rule-making scope of EASA, further evolutions of these Regulations can be expected during 2012.

References to the earlier regulations will be removed from promulgated material, including related CAPs and web pages in due course.

For various service providers and operators of aeronautical radio stations, the regulatory requirements differ. These pages provide the main areas of interest for these various service providers across:

  • Certification and Designation
  • SMS, Hazard Identification, Risk Assessment & Mitigation
  • Operational Procedures, Facilities & Arrangements
  • Personnel Licensing, Certification & Competence
  • Equipment & Interoperability

In addition to requirements related to safety, the various regulations also cover Capacity, Security, Economic and Quality requirements (included within the Single European Sky Common Requirements).

As EASA Regulations and Implementing Rules are developed, they will be promulgated to stakeholders either directly by EASA or by the CAA. The resulting EASA Regulations and Implementing Rules will be placed in the appropriate areas of interest on these pages. The EASA website provides details of regulatory developments.

The CAA also maintains a web page providing details of EASA Regulatory Developments.

In addition to these requirements, there are European Convergence and Safety Plans which have within them requirements to be met in certain time scales and applicable to certain ANSPs. Such plans include the European Single Sky Implementation (ESSIP) and Single European Sky ATM Research (SESAR). As these plans develop, various stakeholders and ANSPs will be engaged in consultation as to how they may be implemented.

For further information regarding the charges for the activities identified on these pages, please see the CAA Scheme of Charges relating to Aerodrome Licensing and Aerodrome Air Traffic Services Regulation and Personnel Licensing.
