This technical specification:
- Provides a methodology for ensuring safety throughout all lifecycle phases of an AGL (Approach Lighting) system, which includes evaluation, design, procurement, manufacturing, installation, commissioning, operational use, maintenance, modification, and decommissioning of the system.
Note 1: This document offers high-level, objective-based, non-prescriptive guidelines intended to allow for a flexible approach in meeting the requirements. - Is applicable to an AGL system at an aerodrome or heliport that offers visual guidance to pilots and is supplied, operated, and maintained by the aerodrome authority.
Note 2: The document may pertain to all or part of an AGL system as deemed necessary by the aerodrome authority. The equipment involved should be defined and listed in the AGL safety case (see section 5.6). Any subsequent additions or modifications to the AGL system must be reported as directed in section 7.7.3. - Primarily targets new AGL systems;
Note: It can also be applied to existing AGL systems or those undergoing modifications. However, relevant documentation for the various project phases may not be available. As a result, retrospective measures to cover applicable lifecycle phases may be implemented, or alternative methods for providing safety information, such as historical data, should be developed. - Addresses all safety aspects, including:
• Operational (functional) safety of the AGL system;
• Electrical safety during installation, maintenance, and decommissioning;
• Environmental safety and electromagnetic compatibility (EMC);
• Health and safety in the workplace. - Supports a regulatory framework that involves auditing a safety management system at an aerodrome. This system must provide documented evidence that safety considerations have been or are being addressed throughout all lifecycle phases. This applies to both projects for installing AGL systems and the routine operational use and maintenance of existing AGL systems.
