FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a Technical
Specification when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical Specifications are subject to review within three years of publication to decide
whether they can be transformed into International Standards.
IEC 61827, which is a Technical Specification, has been prepared by IEC technical
committee 97: Electrical installations for lighting and beaconing of aerodromes.

Enquiry draft Report on voting
97/98A/DTS 97/99/RVC
Full information on the voting for the approval of this Technical Specification can be found in
the report on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
2007. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
A bilingual version of this Technical Specification may be issued at a later date.

INTRODUCTION
Aeronautical ground lighting (AGL) at an aerodrome or heliport provides the pilot of an aircraft
with location, orientation and alignment information in adverse visibility conditions and at night.
This includes those aircraft in flight, i.e. on approach to or take off from the aerodrome, and
those aircraft and other vehicles moving on the aerodrome surface. The type of lighting is
dependent upon the aerodrome operations, type and density of traffic, aerodrome layout and
other environmental considerations and may be realised in many different forms. For the
purpose of this Technical Specification, the various types of lighting, referred to as AGL
services, are considered as components of the overall AGL system.
This Technical Specification describes the system component requirements and it deals with
the inset and elevated luminaires used in AGL.
This Technical Specification should be considered with the AGL requirements produced by the
International Civil Aviation Organisation (ICAO). ICAO requirements are published in the form
of annexes to the Chicago Convention on International Civil Aviation (1944) to which signatory
nations apply to the air traffic and navigation services within their control regions. The annexes
contain Standards and Recommended Practices (SARPs), describing performance
requirements, based on operational requirements, for the safety, regularity or efficiency of
international air navigation. Other ICAO publications contain additional procedures,
performance specifications and guidance material for the interpretation and implementation of
the SARPs.
Annex 14, Aerodromes (Volumes I and II), to the Convention contains the requirements for
aerodrome and heliport operations and includes those aspects relating to AGL. The Aerodrome
Design Manual Doc. 9157 Part 4 (Visual Aids) contains guidance material on the interpretation
of the AGL requirements in Annex 14, Aerodromes. Part 5 of the Aerodrome Design Manual
Doc. 9157 (Electrical Systems) contains technical information on the electrical supply and
installation of AGL Systems. Recommended maintenance policies and practices for AGL
Systems are contained in Part 9 of the Airport Services Manual Doc. 9137 (Airport Maintenance
Practices).
The safety and technical specifications, requirements and working practices within this
International Technical Specification are intended to be compatible with the Standards and
Recommended Practices contained in Annex 14, Aerodromes and to complement the
