AIRFIELD GROUND LIGHTING FOR COMMERCIAL AIRPORTS

Commercial airports depend on reliable Airfield Ground Lighting (AGL) systems to support aircraft movement across runways, taxiways and other operational areas — providing visual guidance during take-off, landing and airfield movement.

Commercial airport projects may involve new installations, airport expansion, system upgrades, retrofit, rehabilitation, testing, commissioning and maintenance. Our application-focused approach considers the complete AGL system — lighting equipment, series circuits, electrical infrastructure, control interfaces and project requirements.

01 · Applications

AGL Applications for Commercial Airports

The applicable configuration for any commercial airport depends on the runway characteristics, operating requirements and approved project design.

Runway Lighting

Supports the visual identification and guidance functions associated with runway operations.

  • Runway edge lighting
  • Threshold lighting
  • Runway end lighting
  • Runway centreline lighting
  • Touchdown zone lighting
  • Approach lighting

Taxiway Lighting

Supports aircraft movement between runways, aprons and other operational areas of the airport.

  • Taxiway edge lighting
  • Taxiway centreline lighting
  • Stop bars
  • Runway guard lighting
  • Holding-position lighting
  • Lead-on and lead-off guidance

Approach & Visual Guidance

Approach lighting, visual approach guidance systems and airfield signs used to support aircraft operations.

  • Approach lighting systems
  • PAPI / APAPI where applicable
  • Airfield guidance signs
  • Runway identification & visual guidance
  • Associated control & monitoring interfaces

Taxiway lighting systems must be considered together with the associated electrical circuits, controls and airport layout — and the actual approach/visual-guidance configuration always depends on the runway, approach type and approved airport design.

02 · Electrical Infrastructure

AGL Electrical Infrastructure

A commercial airport lighting installation is more than a collection of light fixtures — it is an interconnected electrical and control system. System performance depends on the compatibility and condition of the complete installation.

New visual guidance installations
04 · Existing Infrastructure

AGL Retrofit & Upgrade

Existing commercial airports may require modifications or upgrades to maintain or improve their lighting infrastructure. Before modifying an existing system, it should be evaluated for compatibility between new equipment and the installed electrical infrastructure.

Replacement of ageing or damaged components
Runway lighting upgrades
Taxiway lighting upgrades
Series-circuit modifications
Isolating transformer replacement
Primary or secondary connector replacement
LED conversion or retrofit
Rehabilitation support
Control system integration
Testing and commissioning
05 · Verification

Testing, Commissioning & Maintenance

Commercial airport AGL systems may require inspection, testing and verification throughout the project lifecycle, carried out in accordance with applicable project requirements and approved procedures.

Equipment inspection
Series-circuit testing
Electrical checks
Fixture inspection
Connector and transformer checks
Visual inspection
Photometric verification
Fault identification & rectification
System commissioning
Maintenance support
06 · Approach

Why Application-Specific AGL Planning Matters

Every commercial airport has its own operational environment, airfield geometry, existing infrastructure and project requirements. For this reason, AGL equipment should not be selected in isolation.

A system-level approach helps ensure that the selected AGL equipment is appropriate for the intended application.

08 · FAQs

Frequently Asked Questions

What AGL systems are used at commercial airports?
Commercial airports can use runway, taxiway, approach, visual guidance and airfield sign systems depending on the airport configuration and approved design.
Can existing commercial airport AGL systems be upgraded?
Yes. Existing installations can be considered for rehabilitation, component replacement, retrofit and other upgrade requirements, subject to the existing system and project specifications.
Is LED AGL suitable for commercial airports?
LED technology can be considered for suitable AGL retrofit and new-installation applications. The complete system should be evaluated for compatibility, including CCR output, series-circuit operation, isolating transformers, connectors, control systems and photometric performance.
What electrical components are important in a commercial airport AGL system?
Depending on the installation, important components can include CCRs, series-circuit cables, primary connectors, isolating transformers, secondary connectors, lighting fixtures and control or monitoring interfaces.
Does AGL planning involve more than selecting light fixtures?
Yes. AGL should be considered as a complete system involving lighting equipment, electrical infrastructure, control systems, installation conditions, testing and maintenance.
