ICAO 9157 PART 5 AMD 1 PDF

FOREWORD

Proper design, installation and maintenance of electrical systems for visual navigation aids, are prerequisites for the safety, regularity, and efficiency of civil aviation. To this end, this manual provides guidance on the design and installation of electrical systems for aerodrome lighting.

The electrical systems for aerodrome lighting include features which are not usually involved in other electrical installations. This manual therefore examines not only the general features of electrical practices and installations, but also those features which are of special significance for aerodrome installations. It is assumed that readers of the manual will be familiar with electrical circuits and general design concepts, but may not be knowledgeable of certain features of aerodrome installations which are less frequently encountered in other installations. It is important to note that the material presented in this manual is intended to complement national safety codes related to electrical installations.

This manual does not examine electrical systems for buildings located at an airport. Similarly, this manual does not deal with the maintenance of electrical systems. For guidance on this latter issue, the reader is advised to refer to the Airport Services Manual (Doc 9137), Part 9 — Airport Maintenance Practices.
