GACA Updates Airfield Ground and Obstruction Lighting Standards

GACA’s recent update to the airfield ground and obstruction lighting standards introduces a detailed compliance checklist that every Saudi airport owner and contractor must follow. The changes affect equipment specifications, testing procedures and documentation, and they create a clear path for safe, regulated operations.

Why GACA revised the standards

The General Authority of Civil Aviation released the revised documents through its official portal to align Saudi airfield lighting with the latest international safety practices. The update consolidates earlier amendments, adds photometric performance thresholds, and requires electronic monitoring for both runway edge lights and obstruction beacons. It also clarifies the classification of low, medium and high‑intensity obstruction lights, tying each class to a specific maintenance interval.

What the new checklist means on the ground

For owners, the checklist translates into a series of concrete actions. First, every existing fixture must be inspected against the new photometric values; any lamp that falls short must be replaced with a certified unit. Second, the control architecture is required to support real‑time status reporting, meaning that older relay‑based panels often need an upgrade to an AGL Control & Monitoring system. Third, documentation now has to include a signed compliance matrix that references the specific GACA form numbers available on the authority’s website.

Contractors face tighter project timelines. The testing phase, which previously could be scheduled loosely, now has defined windows – typically within 30 days of installation – to capture night‑time performance data. Failure to submit the required test reports on time can delay the issuance of the operational licence for the airfield.

Both owners and contractors must also plan for periodic verification. GACA mandates a full audit every two years, with a mid‑term visual inspection at the 12‑month mark. The audit checklist is now a single downloadable PDF that lists each light type, required intensity, and the monitoring interval.

How Northlane can help you meet the requirements

Northlane Solutions has built a supply chain that matches the new GACA specifications point‑for‑point. Our catalog of Airfield Ground Lighting includes runway edge LEDs, taxiway fixtures and approach lighting systems that meet the updated photometric thresholds. For obstruction beacons, we provide low, medium and high‑intensity models that carry the GACA‑approved certification label.

Our engineering team can design an AGL control architecture that satisfies the real‑time reporting clause. The AGL Control & Monitoring service integrates with existing power distribution, adds fault‑logging capabilities and produces the electronic status files that GACA now expects.

Beyond supply, we offer a full‑service compliance package: on‑site photometric testing, preparation of the compliance matrix, and submission support for the authority’s forms. Maintenance contracts are also available, ensuring that your lighting stays within the performance envelope throughout the two‑year audit cycle.

Observations from recent Saudi projects

In a recent runway upgrade at a regional airport in the Eastern Province, we replaced legacy halogen edge lights with LED units that exceed the new intensity requirements by 15 percent. The project required a temporary control panel upgrade; our AGL monitoring solution was installed in parallel, allowing the airport to pass the 30‑day test window without a single reschedule.

A separate heliport development in Riyadh used our Obstruction Lighting offering. The client opted for solar‑powered high‑intensity beacons to meet the sustainability clause added to the GACA update. Our team handled the installation, performed the required night‑time photometric verification, and filed the compliance documents on the authority’s portal.

Both cases illustrate how early engagement with a certified supplier reduces the risk of non‑compliance and keeps project timelines on track.

FAQ

What are the key new performance thresholds?

GACA now specifies minimum candela values for runway edge, taxiway and approach lights, as well as distinct intensity ranges for low, medium and high‑intensity obstruction beacons. The exact numbers are listed in the updated standard’s annex.

When must existing lighting be upgraded?

Any installation that does not meet the new photometric values must be brought into compliance before the next scheduled audit. For most airports this means completing replacements within the current two‑year audit cycle.

How does Northlane ensure our installation passes GACA’s test?

We supply fixtures that carry the required certification, perform on‑site photometric testing, generate the compliance matrix and submit the electronic status reports through the GACA portal.

What post‑installation support is available?

Northlane offers maintenance contracts that include periodic inspections, spare‑part provisioning and firmware updates for control systems. Our service team remains on call to address any compliance queries that arise during the audit periods.
