Frequently Asked Questions
8 questionsShort answers about the AGL Component Library: what it covers, how to search it, what each component page contains and how to use the values.
Q1What is the AGL Component Library?
The AGL Component Library is a reference catalog of 350 Airfield Ground Lighting components in 22 categories, from runway, taxiway and approach lighting to PAPI/VASI, beacons, obstruction lights, signage, transformers, connectors and control and monitoring equipment.
Q2What categories does the library cover?
The 22 categories are Runway Lighting Components, Taxiway Lighting, Approach Lighting, Visual Glide Slope Systems, Obstruction Lighting, Airport Beacon Systems, Wind & Weather, Sign Boards, CCR & Power Systems, Isolating Transformers, Connectors & Cables, Light Fixture Parts, Mounting Accessories, Control & Monitoring, Navigation Aids, Airfield Sensors, Electrical Infrastructure, Photometry Equipment, Maintenance Equipment, Airport Infrastructure, LED Electronics and Smart Airport Components.
Q3How do I find a specific AGL component?
Use the search box to search by component name or description, or use the category filters to narrow the list. Each result links to that component's own page.
Q4What information does each component page give?
Component pages cover what the part is, where it is used, how it works, typical technical parameters, applicable standards, inspection and maintenance intervals, common field issues and a short FAQ.
Q5Which standards do the component pages reference?
They cite ICAO Annex 14, FAA advisory circulars such as the AC 150/5345 and AC 150/5340 series, IEC standards such as IEC TS 61827, and Indian standards such as IS 7785, depending on the component.
Q6Can I use the typical values on component pages as a design or procurement specification?
No. The values are typical figures for reference and learning. For design, procurement or compliance work, always check the current edition of the applicable standard, your regulator's requirements and the manufacturer's datasheet.
Q7What are the featured deep-dive guides?
They are 13 longer guides on major AGL systems, such as runway lighting, listed at the top of the library, and they sit above the individual part pages for readers who want a system-level overview.
Q8Where can I learn how these components work together as a system?
Precision AGL Academy teaches the complete AGL system, from fundamentals through design, installation, testing, photometry, commissioning, maintenance and troubleshooting. The library catalogs the individual parts, while the Academy covers how they fit together.

Important Notice, Disclaimer & Limitation of Liability
Please read before relying on any content on this page.
- Purpose and intended users. This library is an independent educational and informational reference for competent, suitably trained and authorised airfield ground lighting (AGL) and aerodrome electrical personnel. It is not professional engineering, legal or regulatory advice, and using it does not create any professional or client relationship.
- Safety. Work on series circuits, constant current regulators (CCRs), isolating transformers, cables, connectors and lighting equipment can be fatal. Always apply the aerodrome’s permit-to-work and isolation/LOTO procedures, prove dead, use correctly rated instruments and PPE, and follow the manufacturer’s instructions. Nothing here authorises work on live equipment or the bypassing of any safety device or interlock.
- Aviation operations. Nothing here authorises installation, modification, energisation, adjustment, return to service, a change of operating category (CAT I/II/III), a NOTAM or any aerodrome certification or approval decision. These rest with the aerodrome operator, the air navigation service provider and the competent regulator.
- Specifications, ratings and typical values. Descriptions, parameters, ratings, dimensions, photometric values, wattages, service lives, maintenance tasks and intervals, failure modes, certifications (for example CE, FCC, UL or IEC marks) and part or type designations are general, typical and indicative. They may not match any particular product, make, model or version, and they are not a datasheet, design, specification, selection, sizing, procurement or acceptance criterion. The manufacturer’s current documents, the approved design and the project specification prevail.
- Standards and regulations. References to ICAO, FAA, IEC, IEEE, ISO, BIS, DGCA and other standards are paraphrased summaries for orientation only. They may be incomplete or out of date, and standards are revised from time to time. Consult the current official editions.
