DD IEC TS 62143 pdf download – Electrical installations for lighting and beaconing of aerodromes — Aeronautical ground lighting systems — Guidelines for the development of a safety lifecycle methodology
1 Scope
This technical specification:
outlines a methodology to address the safety at all lifecycle phases of an AGL system,including the evaluation，design，procurement，manufacture，installation，commissioning,operational use, maintenance,modification, and decommissioning of the AGL system;
NOTE 1 This document contains guidelines of a high-level, objective-based, and non-prescriptive nature.Thisis intended to permit a flexible approach to meeting the requirements.
applies to an AGL system at an aerodrome or heliport which provides visual guidance to apilot and is provided, operated and maintained by the aerodrome authority;
NOTE 2 This document may apply to all or a part of an AGL system as required by the aerodrome authority.The equipment covered shall be defined and listed in the AGL safety case (see 5.6).Any subsequent additionor modification to the AGL system shall be notified as directed in 7.7.3.
applies primarily to a new AGL system;
NOTElt may also be applied to an existing AGL system or to an existing AGL system that is being modified;however，the relevant documentation for the project phases may not be available. Therefore,retrospectiveaction to cover the applicable lifecycle phases could be carried out or alternative means of providing safetyinformation should be developed, e.g. historical data.
covers all aspects of safety, including:
. operational (functional safety of the AGL system;
. electrical safety for the installation，maintenance and decommissioning of the AGL
system;
. environmental safety and electromagnetic compatibility (EMC);. health and safety at work.
supports a regulatory regime based on the auditing of a safety management system at anaerodrome，where the safety management system provides documented evidence thatsafety has been or is being addressed at all phases of the lifecycle.This applies equally toa project to install AGL or the routine operational use and maintenance of the AGL.

3Definitions
For the purpose of this International Standard the following definitions apply.
3.1
aerodrome authority
organisation accountable for the safety and security of persons，aircraft operations andfacilities at an aerodrome
3.2
AGL safety case
a controlled document,or set of controlled documents，which clearly and comprehensivelypresents sufficient arguments，evidence and assumptions that all foreseeable hazards havebeen identified and controlled for both engineering and operational areas to demonstrate thatanAGL system is adequately safe
3.3
AGL system safety lifecycle
the safety activities involved in the implementation of an AGL system, occurring during a periodof time that starts at the concept phase of the system and finishes when it is no longeravailable for use and has been decommissioned
3.4
hazard
potential source of harm
NOTEThe term includes hazards to persons arising within a short time scale (for example, fire and explosion) andalso those that have a long-term efect on a person’s health (for example,release of a toxic substance).
3.5
hazard analysis
activity of identifying and evaluating those hazards, often following from some initiating event,that can lead to an accident
3.6
hazardous event
occurrence，with possible hazardous consequences,arising as the result of a hazardouscondition
3.7
impact analysis
activity of determining the effect that a change to a function or component in a system will haveon other functions or components in that system as well as on other systems.
3.8
safety audit
systematic and independent examination to determine whether the procedures specific to thesafety requirements comply with the planned arrangements, are implemented effectively andare suitable to achieve the specified objectives
