25. Aeronautical data
(1)Determination and reporting of air traffic services-related aeronautical data shall be in accordance with the accuracy and integrity requirements specified in Tables I to 5 set out in the Fifth Schedule while taking into account the established quality system procedures.(2)Accuracy requirements for aeronautical data are based upon a 95 per cent confidence level, and in that respect three types of positional data shall be identified—(ii)calculated points derived from mathematical calculations from the known surveyed points of points in space or fixes; and(3)The Air navigation Service Provider shall ensure that integrity of aeronautical data is maintained throughout the data process from survey or origin to the next intended user.(4)The validation and verification procedures shall be based on the applicable integrity classification for—(a)routine data to avoid corruption throughout the processing of the data;(b)essential data to ensure corruption does not occur at any stage of the entire process and may include additional processes as needed to address potential risks in the overall system architecture to further assure data integrity at this level; and(c)critical data to assure corruption does not occur at any stage of the entire process and include additional integrity assurance procedures to fully mitigate the effects of faults identified by thorough analysis of the overall system architecture as potential data integrity risks.(5)Electronic aeronautical data sets shall be protected by the inclusion in the data sets of a 32-bit cyclic redundancy check implemented by the application dealing with the data sets and shall apply to the protection of all integrity levels of data sets as specified in subregulation (4).(6)Geographical coordinates indicating latitude and longitude shall be determined and reported to the aeronautical information services authority in terms of the World GeodeticSystem-1984(WGS-84) geodetic reference datum, identifying those geographical coordinates which have been transformed into WGS-84 coordinates by mathematical means and whose accuracy of original field work does not meet the requirements in Table 1, of the Fifth Schedule.(7)The order of accuracy of the field work and determinations and calculations derived there from shall be such that the resulting operational navigation data for the phases of flight will be within the maximum deviations, with respect to an appropriate reference frame, as indicated in the tables contained in Fifth schedule.
