Doc 9157, Part 5 Amendment No. 1 20/1/20 AERODROME DESIGN MANUAL PART 5. ELECTRICAL SYSTEMS SECOND EDITION AMENDMENT NO. 1 To incorporate this amendment a replace existing pages v, viii, 5-6 and 5-7 with new pages v, viii, and 5-6 to 5-10 dated 20/1/20 b record the entry of this amendment on page iii.
v 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. IMPLEMENTATION The material herein is intended to provide assistance to States for implementation of Annex 14 Aerodromes, Volume I Aerodrome Design and Operations, specifications and thereby help to ensure their uniform application. However, the designer should be aware that local electrical codes may take precedence. FUTURE DEVELOPMENTS In order to keep this manual relevant and accurate, suggestions for improving it in terms of format, content or presentation are welcome. Any such recommendation or suggestion will be examined and, if found suitable, will be included in regular updates to the manual. Regular revision will ensure that the manual remains both pertinent and accurate. Comments on this manual should be addressed to The Secretary General International Civil Aviation Organization 999 Robert-Bourassa Boulevard Montral, Qubec H3C 5H7 Canada The next edition of this manual will include recommendations of, and be in-line with, the future IEC 61820 Standard system design and installation requirements for constant current series circuits for aeronautical ground lighting, expected for 2018. 20/1/20 No. 1
