AGL Comparison Library

Important Notice, Disclaimer & Limitation of Liability

Please read before relying on any content on this page.

1. Purpose and intended users. This page is an independent educational and informational reference for competent, suitably trained and authorised airfield ground lighting (AGL), aerodrome electrical and project personnel. It is not professional engineering, legal or regulatory advice, and using it does not create any professional or client relationship.
2. A comparison is not a requirement or a recommendation. Tables, “at a glance” summaries, pros and cons, and statements of which option is typical, preferred or better are simplified and general. They are not specifications, designs, approved procedures or instructions, and the right choice depends on your project specification, the aerodrome’s category and approved design, and the competent regulator. Nothing here is an endorsement of any technology, product, supplier or method.
3. Standards and regulations. References to ICAO Annex 14 and other ICAO documents, FAA advisory circulars and orders, IEC, IEEE, ISO, BIS, DGCA, AAI and other standards are paraphrased summaries for orientation, not official text. They may be incomplete or out of date, and editions and amendments are revised from time to time. Consult the current official documents. Following this content does not guarantee compliance with any law, standard, contract or regulatory approval. Contract, specification and official requirements always prevail.
4. Safety. Work on series circuits, constant current regulators (CCRs), isolating transformers, cables, connectors and control 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.
5. Aviation operations. Explanations of how lights, signs and systems are used by pilots, vehicle operators or air traffic control are for understanding only and are not operational procedures or instructions. Nothing here authorises return to service, a change of operating category (CAT I/II/III), a NOTAM, a flight-inspection outcome or any aerodrome certification decision. These rest with the aerodrome operator, the air navigation service provider and the competent regulator.
6. Values and figures. Power, current, voltage, photometric, dimensional and time values, categories and tolerances are generic and indicative. Real installations differ by design, make, model, age and condition. Do not use them as design, sizing, test or acceptance criteria without checking the current official source and the manufacturer’s data.
7. Costs, energy and lifecycle. Statements about cost, energy saving, lifetime, reliability or maintenance effort are illustrative tendencies, not measured results, forecasts or guarantees, and are not financial, investment or procurement advice.
8. Generic content; no warranty. Content is provided “as is” and “as available”, without warranty of any kind, express or implied, including accuracy, completeness, currency or fitness for a particular purpose.
9. Limitation of liability. To the fullest extent permitted by applicable law, Precision AGL Academy and its owners, authors and contributors are not liable for any injury, death, loss, damage, downtime, penalty, contractual dispute or regulatory consequence, whether direct or indirect, arising from the use of, reliance on, or inability to use this content. Nothing in this notice excludes or limits any liability that cannot lawfully be excluded or limited.
10. Independence and trademarks. This is an independent publication, not affiliated with or endorsed by ICAO, the FAA, the IEC, IEEE, ISO, BIS, DGCA, AAI, any airport, regulator, certification body or equipment manufacturer. Third-party names, document numbers, standard designations and trademarks belong to their respective owners and are used for identification only.
