AGL FOR RUNWAY REHABILITATION & RETROFIT PROJECTS
Runway rehabilitation can require changes to both civil infrastructure and airport lighting systems. Because new lighting equipment has to work with the existing electrical infrastructure, AGL retrofit planning should consider how new equipment will interact with the existing electrical and lighting infrastructure.
Depending on the project scope, rehabilitation may involve selected component replacement, circuit work, lighting upgrades or broader AGL system modifications. A system-level approach can help coordinate the existing infrastructure with the proposed rehabilitation work.
Typical AGL Rehabilitation Work
The exact scope depends on the condition of the existing installation and the approved rehabilitation requirements.
Existing Infrastructure Assessment
Before retrofit or rehabilitation, the existing AGL system can be reviewed to understand its condition and compatibility with the proposed equipment. This assessment can help identify which components may be retained, replaced or modified during the project.
AGL Component Compatibility
Replacing one component without considering the surrounding system may create compatibility issues. When only selected equipment is being replaced, the new components should be evaluated as part of the complete AGL installation.
Phased Rehabilitation & Retrofit Integration
Airport rehabilitation projects may be executed in phases, allowing specific runway sections, taxiway sections, circuits, lighting groups or components to be upgraded according to the project programme — with a combination of temporary arrangements, component replacement, testing and commissioning as different parts are completed. Retrofit integration should ensure replacement equipment is appropriate for both the existing and proposed system configuration.
Runway & Taxiway AGL Rehabilitation
The actual scope depends on the runway configuration and approved project requirements, and should be coordinated with the wider airfield rehabilitation programme where taxiway lighting is also affected.
Runway Lighting Retrofit
Replacement or modification of lighting equipment associated with the runway.
- Runway edge lighting replacement
- Threshold lighting replacement
- Runway end lighting replacement
- Runway centreline lighting upgrades
- Touchdown zone lighting upgrades where applicable
- Approach lighting modifications
Taxiway & Associated AGL Rehabilitation
Inspection, replacement or modification of associated taxiway lighting infrastructure.
- Taxiway edge lighting replacement
- Taxiway centreline lighting replacement
- Connector & transformer replacement
- Cable work & circuit rehabilitation
- Associated sign replacement
- Testing and commissioning
LED AGL Retrofit During Rehabilitation
Suitable LED lighting can be evaluated as part of a runway rehabilitation or AGL retrofit project. Because the LED fixtures must work with the existing CCRs, series circuits and transformers, LED conversion should be evaluated as a system-level retrofit, not simply as a fixture replacement exercise.
AGL Electrical Components During Rehabilitation
AGL rehabilitation may involve replacement or modification of several electrical components.
AGL Isolating Transformers
Used within the series-circuit arrangement to provide the required electrical interface to the light fixture.
Primary Connector Kits
Used for electrical connections within the primary AGL circuit.
Secondary Connector Kits
Used for connections between the transformer secondary and the lighting fixture.
Primary Cables
May require inspection, replacement or associated circuit work depending on the rehabilitation scope.
Secondary Cables
May require inspection or replacement as part of fixture and transformer work.
Testing & Photometric Verification
Following replacement or rehabilitation, appropriate testing and commissioning can verify that the upgraded installation is functioning as required by the project. Where applicable, photometric testing can be used to assess lighting performance after rehabilitation or retrofit.
AGL Rehabilitation Project Workflow
Each project should be adapted to the condition of the existing system and the approved rehabilitation programme.
Why Application-Specific AGL Planning Matters
Runway rehabilitation projects often involve interaction between existing airport infrastructure and new equipment.
A complete system-level review helps identify the relationship between the existing installation and the proposed rehabilitation work.
