INTERNATIONAL STANDARDS AND
RECOMMENDED PRACTICES
CHAIYTER 1. INTRODUCTION
The object of the aeronautical information service is to ensure
the flow of informatioddata necessary for the safety, regularity
and efficiency of international air navigation. The role and
importance of aeronautical informationfdata changed significantly
with the implementation of area navigation (RNAV),
required navigation performance (RNP) and airborne computerbased
navigation systems. Corrupt or erroneous aeronautical
informationldata can potentially affect the safety of air
navigation.
To satisfy the uniformity and consistency in the provision of
aeronautical informatioddata that is required for the operational
use by computer-based navigation systems, States shall,
as far as practicable, avoid standards and procedures other than
those established for international use.
These Standards and Recommended Practices are to be
used in conjunction with the Procedures for Air Navigation
Services - ICAO Abbreviations and Codes (PANS-ABC,
Doc 8400).
It is recognized that Supplementary Procedures may be
required in certain cases in. order to meet particular requirements
of the ICAO Regions.
Guidance material on the organization and operation of
aeronautical information services is contained in the Aemnautical
Information Services Manual (Doc 8 126).
ANNEX 15
CHAPTER 2. DEFINITIONS
When the following terms are used in the Standards and
Recommended Practices for aeronautical information services,
they have the following meanings:
Accuracy. A degree of conformance between the estimated or
measured value and the true value.
Note.- For measured positional data the accuracy is
normally expressed in terms of a distance fi.om a stated
position within which there is a defined confidence of the
true position falling.
AZSproduct. Aeronautical information provided in the f mof
the elements of the Integrated Aeronautical Information
Package (except NOTAM and PIB), including aeronautical
charts, or in the form of suitable electronic media.
Application. Manipulation and processing of data in support of
user requirements (IS0 19 104*).
ASHTAM. A special series NOTAM notifying by means of a
specific format change in activity of a volcano, a volcanic
eruption andlor volcanic ash cloud that is of significance to
aircraft operations.
Aeronautical data. A representation of aeronautical facts,
concepts or instructions in a formalized manner suitable for Assemble A Process of merging data from sources

processing.
Aeronautical information. Information resulting from the
assembly, analysis and formatting of aeronautical data. Note.- The assemble phase includes checking the data
and ensuring that detected errors and omissions are
