ADR.OPS.A.010 Data quality requirements

GENERAL REQUIREMENTS The aerodrome operator should implement the procedures to:

(a)monitor data relevant to the aerodrome and available services originating from the aerodrome operator, and promulgated by the relevant air traffic services providers;

(b)notify the relevant aeronautical information services, and air traffic services providers of any changes necessary to ensure correct and complete data relevant to the aerodrome, and available services.

FORMAL ARRANGEMENTS

(a)Organisations concerned The aerodrome operator should have formal arrangements with public or private entities providing:

(1)air navigation services;

(2)services for the origination and provision of survey data;

(3)procedure design services;

(4)electronic terrain data; and

(5)electronic obstacle data, with which it exchanges aeronautical data and/or aeronautical information.

(b)Content of formal arrangements Such formal arrangements should include the following minimum content:

(1)aeronautical data to be provided;

(2)the quality requirements for each data item supplied according to the aeronautical data catalogue;

(3)the method(s) for demonstrating that the data provided conforms with the specified requirements;

(4)the action to be taken in the event of discovery of a data error, or inconsistency in any data provided;

(5)the following minimum criteria for notification of data changes:

(i)criteria for determining the timeliness of data provision based on the operational or safety significance of the change;

(ii)any prior notice of expected changes; and

(iii)the means to be adopted for notification;

(6)the party responsible for documenting data changes;

(7)data exchange details such as format or format change process;

(8)any limitations on the use of data;

(9)requirements for the production of data origination quality reports;

(10)metadata to be provided; and

(11)contingency requirements concerning the continuity of data provision.

CONTRACTED ACTIVITIES In case of contracted activities to external organisations for the origination of aeronautical data and aeronautical information, data origination requirements for such organisations are to be found in ATM/ANS.OR.085 of Annex III of Commission Implementing Regulation (EU) 2017/373.

URGENT DISTRIBUTION OF AERONAUTICAL INFORMATION The obligation to comply with the relevant provisions of ADR.OPS.A.010 (Data quality requirements) does not prevent the urgent distribution of aeronautical information necessary to ensure the safety of flight. It is recognised that, in this case, it is not always possible to comply with all the relevant provisions. However, it is also not possible to determine a priori in all cases where this exception may apply; hence this is dependent on a case-by-case individual assessment made by competent staff.

RESOLUTION

(a)Stating that resolution needs to be commensurate with the actual accuracy means that digital data needs to have sufficient resolution to maintain accuracy. Typically, if an accuracy of 0.1 unit is needed, then a resolution of 0.01 or 0.001 units would enable a data chain to preserve the accuracy without any issue. A finer resolution could be misleading as one could assume that it supports a finer accuracy. This factor range of 10 to 100 between accuracy and resolution is applicable regardless of the units of measurements used.

(b)The resolution should be enough to capture the accuracy of the data.

TRACEABILITY Traceability is supported by maintaining the metadata.
