Air Traffic Management: EC 550/2004 (Provision of Air Navigation Services in the Single European Sky)

Motivation and benefits

When issuing the Commission Regulation 550/2004, the European Union prescribed requirements for the provision of air navigation services in the single European sky (service provision regulation).

Article 3 of this regulation allows the National Supervisory Authorities (NSA) to delegate full or parts of inspections and surveys referred to tasks defined in article 2 of this regulation to qualified entity.

These inspections and surveys are based on article 6 (Common Requirements). The requirements are put into force with the Commission Regulations EU 2017/373 and EU 2019/317 which define the common requirements for the provision of air navigation services.

Additionally, air navigation service providers who have inspections and surveys performed directly by the NSA may use the competence of recognised organisations within their internal audit system to show compliance with the common requirements.

  • ensuring safe and efficient provision of air navigation services
  • providing the basis for the certification of air navigation service providers as delegated by through the National Supervisory Authority
  • allowing the compliance with article 6 of EC 550/2004 for NSAs
Target group
  • all National Supervisory Authorities of the EU member states
  • aviation authorities of non EU member states, who are willing to use SES CR in national legislation
  • air navigation service providers, where inspections and surveys are performed by the NSA itself

Based on the guidance material developed by Eurocontrol in the SESIS programme, audit rules and checklists have been developed to provide a documented evidence of compliance to the full set of requirements laid down in EU 2017/373.

As scope of requirements has been extended from finance to safety and security and service quality, a team of competent auditors is required. All auditors accredited
for SES CR have ANS and completed the auditor competence programme, which is surveyed by the Austrian Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation and Technology.
