shall also provide assurance of the applicability period of
intended use of aeronautical data as well as that the agreed
distribution dates will be met.
3.2.6 The order of accuracy for aeronautical data, based
upon a 95 per cent confidence level, shall be as specified in
Annex 11, Chapter 2, and Annex 14, Volumes I and 11,
Chapter 2. In that respect, three types of positional data shall be
identified: surveyed points (runway thresholds, navigation aid
positions, etc.), calculated points (mathematical calculations
from the known surveyed points of points in spaceJfixes) and
declared points (flight information region boundary points).
3.2.7 States shall ensure that the order of publication
resolution of aeronautical data shall be that as specified in
Appendices 1 and 7.
3.2.8 Contracting States shall ensure that the integrity of
aeronautical data is maintained throughout the data process
from surveylorigin to distribution to the next intended user.
Aeronautical data integrity requirements shall be based upon
the potential risk resulting from the corruption of data and
upon the use to which the data item is put. Consequently, the
following classifications and data integrity levels shall apply:
a) critical data, integrity level 1 x there is a high
probabi.lity when using corrupted critical data that the
continued safe flight and landing of an aircraft would be
severely at risk with the potential for catastrophe;
continued safe flight and landing of an aircraft would be
severely at risk with the potential for catastrophe; and
c) routine data, integrity level 1 x lo3: there is a very low
probability when using corrupted routine data that the
continued safe flight and landing of an aircraft would be
severely at risk with the potential for catastrophe.
3.2.9 Aeronautical data quality requirements related to
classification and data integrity shall be as provided in
Tables A7-1 to A7-5 of Appendix 7.
3.2.10 Protection of electronic aeronautical data while
stored or in transit shall be totally monitored by the cyclic
redundancy check (CRC). To achieve protection of the integrity
level of critical and essential aeronautical data as classified in
3.2.8, a 32- or 24-bit CRC algorithm shall apply respectively.
3.2.1 1 Recommendation.- To achieve protection of the
integrity level of routine aeronautical data as classified in
3.2.8, a 16-bit CRC algorithm should apply.
3.2.12 Material to be issued as part of the Integrated
Aeronautical Information Package shall be thoroughly checked
and coordinated with the responsible services before it is submitted
to the aeronautical information service, in order to
make certain that all necessary information has been included
and that it is correct in detail prior to distribution. Validation
and verification procedures shall be established which ensure
that quality requirements (accuracy, resolution, integrity) and
traceability of aeronautical data are met.
Note.- Guidance material on the liaison with other related
services is contained in the Aeronautical Information Services
Manual (Doc 8126).
3.2.13 Demonstration of compliance of the quality system
applied shall be by audit. If nonconformity is identified,
initiating action to correct its cause shall be determined and
taken. All audit observations and remedial actions shall be
evidenced and properly documented.
Note.- Guidance material on the aeronautical data quality
requirements (accuracy, resolution, integrity, protection and
traceability) is contained in the World Geodetic System -
1984 (WGS-84) ~ a n u a(lD oc 9674). Supporting material in
respect of the provisions of Appendices I and 7 related to
publication resolution and integrity of aeronautical data is
contained in RTCA Document DO-201A and European
Organization for Civil Aviation Equipment (EUROCAE)
Document ED-77 - Industry Requirements for Aeronautical
Information.
3.3 Exchange of aeronautical informatioddata
b) essential data, integrity level 1 x lo-': there is a low 3.3.1 Each State shall designate the office to which all
probability when using corrupted essential data that the elements of the Integrated Aeronautical Information Package
2511 1/04 3 -2
Chapter 3 Annex 15 - Aeronautical Information Services
originated by other States shall be addressed. Such an office
shall be qualified to deal with requests for informatioddata
originated by other States.
3.3.2 Where a State designates more than one international
NOTAM office, it shall define the extent of responsibility and
the tenitory covered by each office.
3.3.3 An aeronautical information service shall arrange, as
