PART A U.K. IAIP, aerodrome mapping and electronic obstacle data

1. The aeronautical data and aeronautical information referred to in points (a), (b) and (d) of the second subparagraph of Article 2(1) shall be provided according to a common data set specification which shall: U.K.

(a)

be documented either:

• by using the unified modelling language (UML), specified in the document referred to in point 13 of Annex III, in the form of class diagrams and associated definitions for classes, attributes, associations and lists of values, or

• by using a feature catalogue specified in accordance with the ISO standard referred to in point 25 of Annex III;

(b)

define, as individual data elements, each aeronautical feature for which the information is requested to be published in accordance with the ICAO standards referred to in point 10 of Annex III and the Eurocae document referred to in point 24 of Annex III;

(c)

provide for each attribute the definition of its allowable values in the form of a data type, a range of values or an enumerated list;

(d)

include the definition of a temporal model, UTC based, which can express the complete lifecycle of an aeronautical feature:

• from the creation date and time to the date and time of permanent withdrawal,

• including the permanent changes that create new baselines for that feature;

(e)

include the definition of the rules that may constrain the possible values of the feature properties or the temporal variation of these values. This shall include, as a minimum:

• constraints that impose accuracy, resolution and integrity for positional (horizontal and vertical) data,

• constraints that impose the timeliness of the data;

(f)

apply a naming convention for features, attributes and associations, which avoids the use of abbreviations;

(g)

base the description of geometrical elements (point, curve, surface) on the ISO standard referred to in point 14 of Annex III;

(h)

base the description of the metadata information on the ISO standard referred to in point 15 of Annex III;

(i)

include the metadata items listed in Annex I, Part C.

2. Regarding the ISO standards, the relevant certificate issued by an appropriately accredited organisation, shall be considered as a sufficient means of compliance. The parties referred to in Article 2(2) shall accept the disclosure of the documentation related to the certification to the national supervisory authority upon the latter’s request. U.K.
