EDITORIAL PRACTICES AND

MATERIALS REQUIRING FURTHER DEVELOPMENT


EDITORIAL PRACTICES


1. The text of the amendment is arranged to show new, deleted or moved text
and new text requiring further development or to provide notes on actions
required. Text that has been moved is annotated with the new location at
the end of the text or paragraph, i.e. (Moved to 3.8.2.2). Moved text in
its new location is annotated with the original paragraph number, i.e.
(3.2.13). Examples:


New agreed upon text in BLUE

Line through deleted or moved text

Text requiring further review in RED

Notes on further actions required in RED

Moved text with line through and new location, i.e. (Moved to
3.8.2.2)

Moved text in its new location is annotated with the original
paragraph number, i.e. (3.3.13)

2. A document change history of version numbers is listed for new
iterations of the draft.


3. Changes to the current version during coordination with group members
will be shaded as follows:

Changes to agreed upon text in BLUE

Line through changes to deleted or moved text

Changes to text requiring further review in RED

4. Group members will use "track changes" to make annotations and comments.
The annotations and comments will be included in a spreadsheet and
provided for all members to review as needed.


5. The final draft will show deleted text with a line through it and new
text highlighted with grey shading in accordance with the ICAO practice.


6. The rationale for the revisions will be included in future work on the
draft amendments or in a list referencing each Chapter or paragraph
affected.


mATERIALS REQUIRING FURTHER DEVELOPMENT


7. The draft paragraphs concerning the subject areas listed below were
considered for inclusion in draft Amendment 37 to Annex 15, section
3.8.1, however, were removed and were determined to require further
consideration/development and most likely as guidance materials:


Life cycle management:


Recommendation.- Information life cycle management policies,
processes, practices, and tools should be used to align the quality
assurance requirements of aeronautical information and aeronautical data
with the most appropriate and cost effective infrastructure from origin
through to final disposition. This should include alignment with workflow
processes through management policies and service levels associated with
applications, metadata, information, and data.


Action: Possibly change to more simplified text and incorporate as
future guidance possibly in the QMS Manual, in Doc 8126 or the new PANS-
AIM.


Data handling:


When processes or parts of processes used in the production, storage,
handling, processing, transfer and distribution of aeronautical data are
subject to automation, they shall be:


a) automated to a level commensurate with the context of the data
process;


b) automated to optimize the allocation and interaction of human
and machine to achieve a high degree of safety and quality
benefits from the process;


c) designed to avoid the introduction of data errors; and


d) designed to detect errors in received/input data.


Recommendation.- Data should be entered systematically, from point of
origination to information delivery to meet the integrity of data
requirements as specified in X.X.X for routine, critical, and essential
data.


Note: The systematic entry and delivery of data may be achieved by
employing automation, standard data exchange formats and system
interfaces.


Action: Review and ensure inclusion of concepts that are needed in Doc
8126.


Evidence of data quality:


Aeronautical information and aeronautical data provided to the AIS shall
include evidence of compliance with data quality requirements.


Accuracy and resolution requirements shall be achieved at data origination
and maintained through to publication to the next intended user, including,
whenever the resolution of a data item is reduced or changed, or the data
is translated into a different coordinate reference system or unit of
measurement.


The origin and change history for each data item shall be recorded and
shall be made available for audit;


The aeronautical data or aeronautical information shall be complete; any
missing items shall be declared and resolved;


Data origination, production, storage, handling, processing, transfer or
distribution processes used for each data item shall be defined and shall
be adequate for the assigned level of integrity of the data item;


Data validation and verification processes shall be adequate for the
assigned integrity level of the data item;


Manual or semi-automated data processes shall be performed by trained and
qualified staff, with clearly defined roles and responsibilities;


Tools and/or software used to support or implement the processes shall be
suitable for the purpose;


An effective error reporting, measurement and corrective action process
shall be in operation.


The AIS shall ensure that:


a) the aeronautical information and aeronautical data provided to
them are made available to the next intended user with
sufficient quality to meet the intended use;


b) error reporting, feedback and rectification mechanisms are
established and operated;


c) problems identified during aeronautical information and
aeronautical data origination, production, storage, handling
and processing, or those identified by users after
publication, are recorded and reported;


d) all problems reported concerning aeronautical information and
aeronautical data are analyzed and the necessary corrective
actions are determined;


e) all errors, inconsistencies and anomalies detected in critical
and essential aeronautical information and aeronautical data
are urgently resolved;


f) affected data users are warned of errors, taking into account
the integrity level of the aeronautical information and
aeronautical data; and


g) error feedback from data users and is facilitated and
encouraged.


Action: Review and ensure inclusion of the necessary concepts in the
QMS Manual.


Data protection processes:


Electronic aeronautical data sets shall be protected by the inclusion in
the data sets of a 32-bit cyclic redundancy check (CRC) implemented by the
application dealing with the data sets. This shall apply to the protection
of all integrity levels of data sets as specified in 3.2.10. (3.2.12)


Note 1.- This requirement does not apply to the communications systems used
for the transfer of data sets. (3.2.12, Note 1)


Note 2.- Guidance material on the use of a 32-bit CRC algorithm to
implement a protection of electronic aeronautical data sets is contained in
the Aeronautical Information Services Manual (Doc 8126). (3.2.12, Note 2)


Where the physical size of data exceeds that which may be protected at the
required level of integrity by a single CRC, multiple CRC values shall be
used. (New text)


Prior to publication by the AIS, aeronautical data shall be given an
appropriate level of security protection during storage and exchange to
ensure that the data cannot be accidentally changed or subjected to
unauthorised access and/or alteration. (New text)


The exchange of aeronautical data shall be protected by a suitable
authentication process, such that recipients are able to confirm that the
data has been transmitted by an authorised source. (New text)


Action: Review and ensure inclusion in Doc 8126.
