Overview
EN 50490:2008 (CENELEC / CLC) defines minimum technical requirements for units that provide selective switching and monitoring of individual or groups of lamps in an Aeronautical Ground Lighting (AGL) series circuit. The standard applies to units directly connected to the primary or secondary side of an AGL series circuit and is technology‑neutral. It excludes communication protocols and system‑level AGL behaviour. These units can be used as part of SMGCS or A‑SMGCS surface‑movement lighting systems.

The standard EN 50490:2008 provides comprehensive guidance on the technical requirements for aeronautical ground lighting control and monitoring systems, specifically focusing on units designed for selective switching and monitoring of individual lamps. Its scope is well-defined, addressing the essential framework needed for the electrical installations involved in aerodromes’ lighting and beaconing systems. One of the notable strengths of EN 50490:2008 is its independence from the specific technology utilized for switching or monitoring, ensuring versatility and widespread applicability in enhancing aeronautical ground lighting systems. By stipulating minimum general requirements, it serves as a foundational document that can be adapted across various implementations in aviation environments, ensuring consistency and reliability in ground lighting operations. Furthermore, the standard’s focus on units that are directly connected to the primary or secondary side of an AGL series circuit underscores its practical relevance in real-world settings. This specification ensures that stakeholders can implement effective monitoring and switching solutions to manage the lighting systems critical for the safe surface movement of aircraft. While the document does not delve into communication protocols or system aspects influencing AGL operations, its clarity in delineating the framework for lamp monitoring makes it a vital asset in the aeronautical sector. Moreover, the mention of the potential application of these units within the SMGCS and A-SMGCS systems highlights the standard’s importance in improving airport efficiency and safety through better visual guidance for aircraft movements. Overall, EN 50490:2008 is an essential standard that provides a significant contribution to the standardization of aeronautical ground lighting control, enhancing operational safety and efficiency.
EN 50490:2008は、空港の照明および信号用の電気設備に関する欧州標準であり、特に航空地上灯火（AGL）制御および監視システムのための技術要件を提供しています。この標準は、個々のランプまたはランプのグループを切り替えたり監視したりするためのユニットに関する一般的な最小要件を示しており、幅広い技術に依存しない点が特徴です。 この標準の強みは、AGLシリーズ回路に直接電気的に接続されたユニットに必要な選択的切替および/または監視機能を提供するための基準を明確に定義していることです。これにより、航空機の地上移動を指示または制御するための視覚的手助けとして、SMGCSまたはA-SMGCSの一部として使用できるユニットの基礎が固められています。 また、EN 50490:2008は通信プロトコルやアプリケーション手続きについては扱わず、AGL操作に影響を与えるシステムの側面についても言及しないため、各国が自国のニーズに合わせて柔軟に解釈し、適用することが可能です。このように、標準は急速に進化する技術に対しても適応力を持っており、業界の変化に対する柔軟な対応を促進します。 この標準は、着実な品質の保証と航空分野における安全性の向上に貢献しており、特に航空機の地上運用における重要な役割を果たします。そのため、EN 50490:2008は、航空関連業界において必要不可欠な基準であり、選択的切替および監視システムの実装を行う際の信頼できる指針として機能します。
Die Norm EN 50490:2008 bietet einen klaren und umfassenden Rahmen für die technischen Anforderungen an Systeme zur Steuerung und Überwachung der aeronautischen Bodenbeleuchtung (AGL) an Flugplätzen. Ihr Anwendungsbereich erstreckt sich auf Einheiten, die unabhängig von der verwendeten Technologie für das Schalten und/oder Überwachen einzelner oder gruppierter Lampen in einem AGL-Reihenschaltungssystem sind. Dies bedeutet, dass die Norm eine wesentliche Grundlage für die Entwicklung und Implementierung von steuerbaren Beleuchtungssystemen im Luftfahrtbereich darstellt. Ein hervorzuhebendes Stärkenmerkmal dieser Norm ist die klare Definition der Mindestanforderungen für die betreffenden Einheiten, die direkt elektrisch mit der Primär- oder Sekundärseite eines AGL-Reihenschaltungssystems verbunden sind. Dies sorgt für eine einheitliche Grundlage, die sowohl Herstellern als auch Betreibern hilft, die benötigten Funktionen für das selektive Schalten und Überwachen von Lampen effizient umzusetzen. Die Relevanz der EN 50490:2008 zeigt sich in der Notwendigkeit, die Sicherheit und Effizienz der Luftverkehrssteuerung durch visuelle Hilfen zu gewährleisten. Obwohl die Norm keine Kommunikationsprotokolle und Anwendungsverfahren abdeckt, konzentriert sie sich auf die wesentlichen technischen Anforderungen, die für den ordnungsgemäßen Betrieb von AGL-Systemen erforderlich sind. Die Einheiten, die gemäß dieser Norm entwickelt werden, können sowohl in einem Surface Movement Guidance Control System (SMGCS) als auch in einem Advanced Surface Movement Guidance and Control System (A-SMGCS) eingesetzt werden, um die Oberflächenbewegungen von Flugzeugen sicher zu leiten und zu steuern. Insgesamt trägt die EN 50490:2008 wesentlich zur Standardisierung und Verbesserung der aeronautischen Bodenbeleuchtung bei, indem sie klare Richtlinien bereitstellt, die sowohl die Sicherheit als auch die Effizienz des Luftverkehrs unterstützen.
이 표준 문서 EN 50490:2008은 공항의 조명 및 신호 장비에 필요한 전기 설치에 대한 기술적 요구사항을 정의하고 있습니다. 주요 초점은 항공기 지상 조명 제어 및 모니터링 시스템의 개별 조명 기구 선택 스위칭 및 모니터링을 위한 유닛에 대한 최소 프레임 요건을 제공하는 것입니다. 이 표준은 AGL(항공기 지상 조명) 시리즈 회로와 직접 전기적으로 연결될 필요가 있는 유닛에 적용되며, 조명 기구의 선택적 스위칭과 모니터링을 위한 필수 요소로 설정되어 있습니다. EN 50490:2008의 강점 중 하나는 다양한 기술에 독립적인 요구 사항을 제시하여, 사용자가 선택한 기술을 기반으로 조명 기구를 효율적으로 운영할 수 있도록 지원합니다. 이는 특히 여러 종류의 조명 기술이 공존하는 환경에서 유용하며, 유연성을 높이는 것이 큰 장점이라고 할 수 있습니다. 또한, 이 표준은 SMGCS(지상 이동 제어 시스템) 또는 A-SMGCS(고급 지상 이동 제어 시스템)의 일부로 사용되어, 항공기의 지상 이동을 시각적 보조 장치를 통해 안내하거나 제어하는 데 기여할 수 있습니다. 다만, 이 표준은 통신 프로토콜이나 응용 절차에 대해서는 다루지 않으며, AGL 운영에 영향을 미치는 시스템 측면을 다루지 않는다는 것을 명시하고 있습니다. 이는 한편으로는 표준의 범위를 명확하게 하고, 사용자가 필요한 정보를 집중적으로 찾아볼 수 있도록 도와줍니다. 전체적으로 EN 50490:2008은 항공 조명 분야에서 꼭 필요한 기술적 요구 사항을 제공함으로써, 조명 기구의 안전하고 효율적인 운영을 위한 기초를 공고히 해줍니다.
La norme EN 50490:2008 est un document fondamental pour les installations électriques destinées à l'éclairage et au balisage des aérodromes, spécifiquement pour les systèmes de contrôle et de surveillance de l'éclairage aéronautique au sol. Cette norme européenne établit des exigences techniques minimales générales pour les unités indépendantes, quelle que soit la technologie utilisée pour le fonctionnement ou la surveillance des lampes, qu'elles soient individuelles ou groupées dans un circuit AGL. L'un des points forts de cette norme réside dans sa capacité à s'appliquer aux unités directement connectées aux côtés primaire ou secondaire d'un circuit AGL, garantissant ainsi un contrôle sélectif et une surveillance efficace des lampes. Cela assure une grande flexibilité d'application, car ces unités peuvent faire partie intégrante d'un SMGCS ou d'un A-SMGCS, permettant ainsi de guider et de contrôler le mouvement au sol des aéronefs par le biais d’aides visuelles. Bien que la norme précise l'envergure des exigences techniques, il est essentiel de noter qu'elle ne couvre pas les protocoles de communication ni les procédures d'application. Cela pourrait être un aspect à considérer pour les utilisateurs souhaitant des solutions globales incluant à la fois le contrôle des lampes et les systèmes de communication. De plus, la norme ne traite pas des aspects systémiques qui influent sur le fonctionnement de l'AGL, ce qui souligne la nécessité pour les professionnels de se référer à d'autres documents normatifs pour une compréhension complète du système dans son ensemble. La pertinence de la norme EN 50490:2008 est évidente pour les opérateurs d'aérodromes cherchant à établir des installations conformes et efficaces pour l'éclairage et le balisage au sol. En fournissant des exigences claires et minimales, cette norme joue un rôle crucial dans l'amélioration de la sécurité des opérations au sol, tout en facilitant l'implémentation de solutions techniques adaptées aux besoins spécifiques de chaque aéroport.
