AIS.TR.240 Data limitations

ANNOTATION

(a)The objective of such an annotation is to notify the users of the AIS products including their aeronautical data that specific quality requirements are not met and may, therefore, compel limitations in the operational use of the relevant aeronautical data.

(b)The following principles apply:

(1)the solution applies for both the eAIP and paper AIP;

(2)the use of the ‘asterisk’ is undesirable because it is already used for WGS-84 issues;

(3)the non-compliance covers all parts of the AIP, i.e. textual aeronautical data and charts; and

(4)non-compliant aeronautical data items shall be individually and explicitly identified and the use of any general statement with the intention of covering a range of data items shall be avoided.

(c)The AIP section GEN 1.7 is used to identify non-compliant aeronautical data items. A new sub-header should be introduced at the end of the current section named ‘Data non-compliant with European Commission Regulation (EU) 2017/373’.

(d)Within AIP GEN 1.7, the following two alternatives are proposed. The choice of which depends on national practicalities being based either on the amount of annotations to be published or on individual existing operational or technical constraints.

(1)Annotation alternative 1 Alternative 1 is recommended if the number of identified non-compliances covers no more than two AIP pages. The relevant non-compliant data items shall be listed in a table, including as a minimum: — specific data item; — AIP section(s) concerned; — reason for non-compliance; — Notes/remarks. Proposed table format:

(2)Annotation alternative 2 Alternative 2 is recommended if the number of non-compliances extends more than two AIP pages. It should then contain a general (global) statement to indicate ‘Several data items are not compliant with the given regulation – details can be found online via <link>’. The link shall direct the user to a list on the website which must support compliance with minimum requirements: the list must be accessible online. Note: The indication of ‘available on request’, or similar, is clearly insufficient. The list must be kept up to date and fully synchronised (consistent) with the AIP update cycles, as relevant. This list should be in the form of a table as indicated under alternative 1 noting that it will be made available to users as an extra element outside the AIP.
