Technical correction ATM/ANS 2026: what changes for airports and providers

Key data

Certified air navigation service providers in the EU have a regulatory correction on their agenda that they cannot ignore. The correction published on May 26, 2026 rectifies material errors in the Implementing Regulation (EU) 2020/469, a regulation that profoundly modified the rules on air traffic management (ATM) and air navigation services (ANS) throughout the European Union.

The problem with corrections of material errors is that, although they do not introduce new obligations from scratch, they can alter the exact scope of requirements already in force. If your organization implemented procedures based on the original version of Regulation (EU) 2020/469, this correction may change what the regulation actually requires.

What does this regulation establish?

The correction affects four specific technical areas of Implementing Regulation (EU) 2020/469. The following details the modified regulations and the matters affected:

The corrections focus specifically on four thematic blocks:

• Technical requirements for ATM/ANS providers: correction of errors in the requirements applicable to certified air traffic management and air navigation service providers.
• Airspace structure design: rectification of errors in the criteria for airspace design and classification.
• Aeronautical data quality: correction of errors in the quality standards applicable to aeronautical data published and distributed.
• Runway safety: rectification of errors in the operational and technical requirements related to runway safety at airports.

The original regulation now being corrected — Regulation (EU) 2020/469 — was published on February 14, 2020 and its initial version appeared in the EU Official Journal on April 3, 2020 (OJ L 104).

Economic and operational impact

Corrections of material errors in aeronautical technical regulations have a direct operational impact, although they do not always involve new costs. The real risk lies in two scenarios:

• Incorrectly implemented procedures: if the organization applied the erroneous version of the regulation, current operational procedures may not be compliant with the corrected regulation. This requires review and, where appropriate, updating of manuals, systems and training.
• Altered compliance deadlines: if the correction modifies dates or conditions for the application of certain requirements, already approved implementation plans may become outdated.

The economic impact will depend on the exact scope of each correction in the official text. However, the costs of review and adaptation are inevitable for any certified provider that has implemented procedures based on Regulation (EU) 2020/469.

In the case of Spain, ENAIRE is the certified air navigation service provider that manages Spanish airspace and is therefore the main affected party at the national level. Airports managed by AENA may also be affected regarding runway safety requirements.

Who does it affect?

• ENAIRE: air navigation service provider in Spain, directly affected by the corrected ATM/ANS requirements.
• EU airports: especially regarding runway safety requirements and aeronautical data quality.
• AENA: as airport operator, affected by the technical requirements for aerodromes of Regulation (EU) 139/2014.
• State Aviation Safety Agency (AESA): as Spanish civil aviation authority, must verify the impact of corrections on supervision and certification procedures.
• Other certified ATM/ANS providers in the EU: any organization certified under Regulation (EU) 2017/373 that has implemented procedures based on the original version of Regulation (EU) 2020/469.
• Regulatory compliance and quality departments: responsible for keeping operations manuals and safety management systems up to date.

Practical example

An air navigation service provider certified under Regulation (EU) 2017/373 implemented in 2021 an aeronautical data quality management procedure based on the requirements of Regulation (EU) 2020/469 as originally published in OJ L 104 of April 3, 2020.

If the correction now published rectifies a material error in the aeronautical data quality requirements — one of the four affected blocks — the procedure implemented in 2021 may not be compliant with the corrected regulation. The provider must:

1. Compare the original text with the corrected text in the aeronautical data quality block.
2. Identify whether the corrected error affects the requirements already implemented.
3. Update the procedure, operations manual and, where appropriate, staff training.
4. Document the review to demonstrate compliance to the competent authority (AESA in Spain).

This process, although it does not necessarily involve high economic cost, does require technical and legal review time that must be planned urgently.

What should companies do now?

1. Access the official text of the correction published in the EU Official Journal on May 26, 2026 and compare it with the original text of Regulation (EU) 2020/469 (OJ L 104, April 3, 2020).
2. Identify the blocks affected by the corrections: technical ATM/ANS requirements, airspace structure design, aeronautical data quality and runway safety.
3. Review current operational procedures in each of those blocks to verify whether they were implemented in accordance with the erroneous version or the corrected version.
4. Update manuals, systems and training in cases where the correction modifies the scope or requirements of already implemented procedures.
5. Coordinate with AESA (in the case of Spanish organizations) to confirm whether the competent authority has issued guidance on the implementation of the corrections.
6. Document all reviews and updates to demonstrate compliance with the corrected regulation to the supervisory authority.

Frequently asked questions

Q: Does this correction introduce new obligations?
A: No. Corrections of material errors rectify existing obligations, but may alter their exact scope or application conditions. The obligations themselves were already in force under the original Regulation (EU) 2020/469.

Q: When does the correction enter into force?
A: The published text does not specify an entry into force date. It is advisable to consult the official EU Official Journal or AESA for clarification on the applicable date.

Q: Does ENAIRE have to update its procedures?
A: Yes. ENAIRE, as a certified air navigation service provider, must review whether the corrected errors affect the procedures it has implemented and update them if necessary.

Q: What happens if we do not comply with the corrected regulation?
A: Non-compliance with applicable regulations can result in supervisory actions, sanctions or suspension of certification by the competent authority (AESA in Spain).

Q: Who should lead the review process in our organization?
A: The review should be coordinated between the legal/compliance department and the technical departments responsible for the affected operational areas (ATM/ANS, aerodrome operations, data quality, runway safety).
