PART D Data origination

1.The surveying of radio navigation aids and the origination of calculated or derived data whose coordinates are published in the AIP shall be carried out in accordance with appropriate standards and at least in accordance with the relevant ICAO provisions referred to in point 20 of Annex III.

2.All surveyed data shall be referenced to WGS-84 as specified in the ICAO provisions referred to in point 2 of Annex III.

3.A geoid model, sufficient to meet the ICAO provisions referred to in point 3 of Annex III and the aeronautical data and aeronautical information quality requirements laid down in Annex IV, shall be used in order that all vertical data (surveyed, calculated or derived) may be expressed relative to mean sea level via the Earth Gravitational Model 1996. A ‘geoid’ means the equipotential surface in the gravity field of the Earth, which coincides with the undisturbed mean sea level extended continuously through the continents.

4.Surveyed, calculated and derived data shall be maintained throughout the lifetime of each data item.

5.Survey data categorised as critical or essential data shall be subject to a full initial survey, and thereafter shall be monitored for changes on a yearly basis, as a minimum. Where changes are detected, re-survey of the relevant data shall be undertaken.

6.The following electronic survey data capture and storage techniques shall be employed:

(a)

reference point coordinates shall be loaded to the surveying equipment by digital data transfer;

(b)

the measurements in the field shall be stored digitally;

(c)

raw data shall be digitally transferred and loaded into the processing software.

7.All survey data categorised as critical data shall be subject to sufficient additional measurement to identify survey errors not detectable by single measurement.

8.Aeronautical data and aeronautical information shall be validated and verified prior to use in deriving or calculating other data.
