The Civil Aviation Authority (CAA) and National Air Traffic Services Ltd (NATS) are working collaboratively with all Stakeholders to support the implementation of aeronautical data quality requirements in the United Kingdom by providing regulatory oversight of
data chains from origination to publication by Aeronautical Information Services (AIS).
As advised in the
Information Notice IN-2017/019 (11 May 2017), the CAA has updated the oversight programme to include verification of the compliance of Aerodrome Operators with the data requirements contained in Commission Regulation EU 139/2014, applicable to EASA certificated aerodromes and
Commission Regulation EU 73/2010 (Aeronautical Data Quality), applicable to EASA certificated aerodromes and all aerodromes with Instrument Flight Procedures (IFP).
Aerodrome Operators are expected to demonstrate their compliance during audits of aeronautical data and information activities. When an Aerodrome Operator fails to provide evidence that aerodrome survey is compliant with
EU 139/2014 and
EU 73/2010, it will be required to deliver a full initial survey before the date of their next scheduled 5-year Instrument Flight Procedure review and that should be reflected in the corrective action and implementation plan.
The CAA will provide aerodrome survey guidance for Aerodrome Operators and other data originators (including contracted activities), which will support compliance with the Regulation (EU) 139/2014 and ICAO Annex 4, Annex 11 and Annex 14.
The CAA guidance will complement existing AMC and GM to EU 139/2014 and the
Eurocontrol - Terrain and Obstacle Data Manual and should therefore be used in conjunction with those documents. The guidance will be published as a new CAP in Q3 2018 and will replace CAP 232 applicability for EASA certificated aerodromes and all aerodromes with Instrument Flight Procedures.
One of the key requirements of the aeronautical data regulations is the establishment of formal arrangements between all parties involved in the exchange of aeronautical data and by 1 May 2018 NATS AIS will send formal arrangement templates to Accountable Managers and registered data sponsors.
Formal arrangements with NATS shall be signed on behalf of an organisation by the Accountable Manager or a competent person formally appointed by the Accountable Manager to be directly responsible for all aeronautical data activities and aeronautical information provision activities at
the aerodrome. This should be provided within 15 working days from the delivery date. In due course, the signatory will be required to provide a full list of authorised individuals, who are responsible for submitting changes to AIS products within a clearly defined scope of authorised changes (data items).
The signatory will also be responsible for updating and maintaining this list on a regular basis.
As described in IN-2017/019, NATS is currently implementing a new aeronautical information management system, known as project ‘AURORA’ which has been specifically designed to meet EU 73/2010 and Eurocontrol Specifications. It is intended to be fully operational from Q4 2018.
Only signatories of organisations who have a signed Formal Arrangement with NATS will be allowed to nominate users to have access to the Data Originators Portal and act on their behalf. Every individual user will be required to register on the portal and will be assigned the authorisations
and responsibilities of those previously documented in their organisations formal arrangements.
Any entity that has not received a formal arrangement template from NATS by 18 May 2018 and consider themselves responsible for originating data and submitting changes to AIS products should contact the AIS Supervisor at
The UK CAA organised a workshop for data originators to help stakeholders meet ADQ requirements.
