AIRFIELD GROUND LIGHTING IN INDIA

Systems, products, testing and services for runway and taxiway lighting, approach lighting, PAPI, CCRs, transformers, cables, photometry, commissioning and maintenance at Indian airports.

A practical guide to the Indian AGL market and engineering scope — consultants, contractors, manufacturers, photometry specialists and project support across the complete airfield lighting lifecycle.

01 · Overview

AGL in India at a Glance

Airfield Ground Lighting (AGL) systems are critical visual aids used at airports for runway, taxiway, approach and aircraft movement operations.

In India, AGL projects involve multiple engineering disciplines including lighting design, electrical infrastructure, series circuits, Constant Current Regulators (CCRs), isolating transformers, cables, connectors, light bases, airfield signs, PAPI, photometry, testing, commissioning and maintenance.

The Indian airport sector includes a wide range of AGL requirements, from runway and taxiway lighting upgrades to CAT I/CAT II/CAT III approach systems, PAPI installations, photometric testing, control and monitoring systems and long-term maintenance contracts.

Airports Authority of India procurement records show continuing demand for specialist AGL services in India, including photometric testing and annual maintenance of AGL systems. For example, AAI published a 2026 annual maintenance contract for AGL and related E&M installations at Thoothukudi Airport, while other AAI tenders have covered field photometric testing at airports including Rajkot, Kushinagar and Surat.[1]

India's aerodrome regulatory framework is based on DGCA requirements together with applicable ICAO Standards and Recommended Practices. The Ministry of Civil Aviation reported that amendments were made during 2025 to CAR Section 4, Series B, Part I, Aerodrome Design and Operations, incorporating changes proposed by ICAO and requirements arising from airport development projects.[2]

This guide explains the AGL market and engineering scope in India, including AGL products, consultants, contractors, manufacturers, photometry, testing, maintenance and project execution.

02 · AGL Systems

AGL Systems in India

Airfield Ground Lighting systems in India can range from a small regional airport lighting installation to complex systems supporting high-capacity international airports and low-visibility operations.

Approved airport design
Existing infrastructure

Indian AIP data illustrates the diversity of installed systems. Published aerodrome information includes combinations of PAPI, CAT I and CAT II approach lighting, runway centreline lighting, runway edge lighting, touchdown-zone lighting and taxiway lighting at different airports.[3]

03 · Runway, Taxiway & Approach

Runway, Taxiway & Approach Lighting in India

Runway lighting is one of the most important parts of an airport's visual-aid infrastructure. The exact system depends on runway classification and operating requirements.

Runway Lighting

Indian AIP publications show runway lighting configurations varying between airports, including PAPI, CAT II approach lighting, centreline and touchdown-zone lighting.[3]

  • Runway edge lights — define the lateral limits of the runway
  • Threshold lights — identify the threshold for arriving aircraft
  • Runway end lights — required visual indication at the runway end
  • Runway centreline lights — longitudinal guidance where enhanced guidance is needed
  • Touchdown zone lights — guidance in the touchdown area

Taxiway Lighting

Supports safe aircraft movement between runways, aprons, terminals and other manoeuvring areas. Arrangements vary with airport layout and operational requirements.[4]

  • Taxiway edge lights
  • Taxiway centreline lights
  • Stop bars
  • Runway guard lights
  • Turning/curve lighting where applicable
  • Associated signs and guidance systems

Approach Lighting

Gives visual guidance in the final stages of approach. For low-visibility operations the serviceability of specific elements can directly affect whether operations continue.[5]

  • Elevated approach lights
  • Inset approach lights
  • Crossbars
  • Centreline lighting
  • Sequenced lighting
  • PAPI and associated approach guidance equipment

Taxiway lighting may also be integrated into the airport control system so that operators can select the required circuits and intensity levels according to operational conditions.

04 · PAPI

PAPI in India

PAPI — Precision Approach Path Indicator — is one of the most widely searched and commercially important airport lighting systems. A standard PAPI provides visual approach-slope guidance through five combinations of white and red lights.

4 White

Well above the slope

3 White + 1 Red

Slightly above

2 White + 2 Red

On the approach slope

1 White + 3 Red

Slightly below

4 Red

Well below the slope

Indian AIP publications routinely identify PAPI installation data, including side of runway, nominal approach angle and MEHT information. For example, current Indian aeronautical information records PAPI installations using a nominal 3° indication at multiple aerodromes.[3]

PAPI work in India can involve
PAPI supplyPAPI installationPAPI foundationPAPI sitingPAPI alignmentPAPI aimingPAPI electrical connectionPAPI functional testingPAPI photometryPAPI maintenancePAPI troubleshooting
Evaluating a PAPI supplier or manufacturer

PAPI is a specialised product category. Do not select a PAPI purely on price and number of units — the complete optical and installation system must be evaluated.

05 · Electrical Systems

AGL Electrical Systems, CCRs, Transformers & Cables in India

The electrical system behind AGL is as important as the visible light fixtures. A typical series-circuit arrangement is shown below.

Constant Current Regulator
Primary Series Cable
Primary Connector
Isolation Transformer
Secondary Connector
AGL Light Fixture
The electrical infrastructure may also include
CCR controlALCMS / SCADAMonitoringStandby powerUPS systemsDG backupChangeover systemsProtection systemsGrounding and bondingCable fault monitoring

Constant Current Regulators (CCR)

A CCR regulates the current in many airport series lighting circuits: it controls the series-circuit current while the output voltage varies with the connected load. For FAA-based equipment, AC 150/5345-10H is the current specification for CCRs and regulator monitors. For Indian projects, the equipment requirement should be set by the approved project specification, the applicable DGCA/ICAO framework and purchaser requirements.

  • Multiple intensity steps
  • Local and remote control
  • Monitoring and fault indication
  • Circuit protection
  • Integration with ALCMS

Airport Isolating Transformers

Isolation transformers are used extensively in series-circuit AGL and form the interface between the primary series circuit and each individual light fixture. For FAA projects, L-830/L-831 classifications apply according to frequency; for Indian projects, the approved project and authority requirements govern product selection.

  • 6.6 A and 20 A applications
  • 20/6.6 A configurations
  • Various wattage ratings
  • 50 Hz / 60 Hz requirements according to system
  • Environmental protection and watertight construction
  • Approved connector arrangements

AGL Cables & Connectors

Cable systems form the electrical backbone of airport series lighting. A cable that is electrically continuous but has degraded insulation is not necessarily acceptable — so commissioning should include both continuity and insulation integrity where required.

  • Primary and secondary cable
  • Primary and secondary connectors
  • Cable assemblies and terminations
  • Junction boxes
  • Circuit length and insulation requirements
  • Environmental exposure, mechanical protection and routing
  • Water ingress and connector accessibility
06 · Airfield Signs

Airfield Signs in India

Airport signs are another important part of the visual guidance system.

AGL sign systems can include
Direction signsLocation signsMandatory instruction signsRunway designation signsTaxiway signsStand / runway information signsDistance-to-go signsOther airport visual guidance signs
Sign projects can involve
Structural installationElectrical supplyIlluminationControlMonitoringSign identificationMaintenance

For FAA projects, airport sign standards are covered by dedicated FAA publications; Indian projects should follow the applicable DGCA, ICAO and airport requirements.

07 · Control, Monitoring & Power

AGL Control, Monitoring & Secondary Power in India

Modern airport lighting increasingly depends on centralised control and monitoring. A simplified architecture is shown below.

ATC / Airport Operations
AGL Control System
CCR / Circuit Controllers
Series Lighting Circuits
Runway / Taxiway / Approach Lights
Status Feedback
The control system can provide
Lighting ON/OFFIntensity selectionCircuit selectionFault indicationStatus monitoringAlarm handlingEvent loggingRemote diagnostics

An Indian AGL supplier, for example, publicly lists ALCMS, CCRs, circuit selectors, remote-control desks and junction boxes among its airfield-lighting products.[10]

Secondary power for AGL

Secondary power is critical for lighting systems supporting low-visibility operations. Airport power architecture may include:

Utility supplyDG generatorsUPSAutomatic changeoverPower distributionAGL-specific supplyIndependent supplies for critical lighting

The required switch-over performance depends on the airport's operational category and applicable standards. Indian AIP material shows that airports may distinguish between lighting systems requiring very fast transfer and other systems with longer permitted switch-over periods.[6] This is an important design consideration for CAT II/CAT III airport lighting projects.

08 · AGL Photometry

AGL Photometry & Photometric Testing in India

AGL photometry gives objective measurement of the optical performance of installed lighting — and it is one of the strongest specialist-service requirements in the Indian airport sector.

What a visual inspection tells you

A visual inspection can tell an engineer: "The light is operating."

What photometry tells you

Photometry can answer: how much light is being produced, where it is being directed, what its optical performance is, and how that compares with the applicable requirement or previous baseline.

Photometry can evaluate
IntensityBeam coverageBeam distributionColourChromaticityOrientationAlignmentConfigurationFixture-to-fixture consistency
Photometry may be required for
Runway edge lightsRunway threshold lightsRunway end lightsRunway centrelineTouchdown zone lightsApproach lightsTaxiway edge lightsTaxiway centreline lightsStop barsPAPIOther visual aids

AAI procurement records show that specialist field photometry is an active airport requirement in India. Recent AAI procurement examples include photometric testing at Rajkot, Kushinagar and other airports, and a current 2026 AAI tender for AGL photometric testing and reporting at Thoothukudi Airport.[1] Indian airport procurement also shows photometric testing frequently bought as a specialist service rather than simply as part of equipment supply.[11]

A professional photometry service may include

Field measurement

Measurement of installed fixtures using calibrated photometric equipment.

Alignment measurement

Determination of fixture orientation and optical beam alignment.

Colour / chromaticity

Evaluation of the applicable colour characteristics.

Intensity measurement

Light output measured under the specified operating condition.

Beam measurement

Evaluation of the applicable angular distribution and coverage.

Reporting

Preparation of traceable technical reports.

Corrective support

Identifying fixtures that need cleaning, adjustment, repair or replacement.

Retesting

Verification after corrective action.

AAI tender specifications illustrate the breadth of Indian AGL photometric requirements, including field measurement of intensity, beam spread, orientation and chromaticity and the submission of test reports.[7]

Runway photometry

For airports undertaking rehabilitation or regulatory observations, field photometry provides the objective evidence needed to identify deficient fixtures.

  • Runway edge, threshold and end light testing
  • Centreline and touchdown zone testing
  • Approach lighting testing
  • Alignment, colour / chromaticity and intensity
  • Data collection, report generation
  • Corrective recommendations and retesting

Taxiway photometry

Scope runs: Measurement → Evaluation → Identification → Corrective Support → Retest → Report.

  • Taxiway edge lights
  • Taxiway centreline lights
  • Stop bars
  • Runway guard lights
  • Other taxiway visual aids

Assessing a photometry company

The ability to sell airport lights does not automatically mean an organisation can perform professional runway photometry.

  • Calibrated photometric equipment
  • Mobile measurement capability
  • Trained personnel
  • Runway/taxiway and PAPI testing experience
  • Alignment and colour/chromaticity capability
  • Data management, reporting and retesting

Photometry is valuable for commissioning, DGCA observations, periodic inspection, maintenance, rehabilitation, acceptance and troubleshooting. AAI's ongoing procurement of field photometric services is practical evidence that this is an active requirement across Indian airports.[1]

09 · Testing & Commissioning

Airport Lighting Testing & Commissioning in India

Airport lighting testing can be divided into several stages, from pre-commissioning checks to final acceptance and handover.

Pre-commissioning testing

  • Visual inspection
  • Cable identification
  • Continuity
  • Insulation resistance
  • Transformer inspection
  • Connector inspection
  • Circuit checks

Electrical commissioning

  • CCR
  • Circuit current
  • Circuit resistance / impedance
  • Control
  • Monitoring
  • Standby power

Functional testing

  • ON / OFF
  • Brightness steps
  • Interlocks
  • Control-system response
  • Emergency operation where applicable

Optical testing

  • Photometry
  • Alignment
  • Colour
  • Intensity
  • Beam coverage

Final acceptance

  • Punch-list closure
  • Retest
  • Final report
  • As-built documentation
  • Handover

Airport lighting testing company

The key question is whether the company can test the complete AGL system, rather than one isolated component.

  • Cable, insulation and continuity testing
  • Transformer and CCR testing
  • Circuit measurements
  • Brightness-step and functional testing
  • Photometry, PAPI and sign testing
  • Control-system testing and commissioning
10 · Maintenance & Troubleshooting

AGL Maintenance & Troubleshooting in India

Airport lighting maintenance is a recurring requirement rather than a one-time project activity.

Preventive maintenance

  • Visual inspection
  • Cleaning
  • Connector, transformer and cable inspection
  • CCR inspection
  • Control-system inspection

Corrective maintenance

  • Failed lights and low intensity
  • Intermittent lights
  • Transformer and connector failures
  • Cable faults
  • CCR faults
  • PAPI faults

Periodic testing

  • Electrical testing
  • Photometry
  • Alignment
  • Control testing
  • PAPI verification

AAI's procurement records demonstrate that airport operators continue to procure dedicated AGL maintenance services in addition to one-time installation and testing work. For example, AAI currently lists a 2026–28 annual maintenance contract for AGL and E&M installations at Thoothukudi Airport.[1]

11 · CAT I, II & III

AGL in CAT I, CAT II and CAT III Operations, and Low-Visibility Operations

AGL requirements become increasingly demanding as runway operations move toward lower visibility.

Systems supporting CAT II/III operations may involve

  • Precision approach lighting
  • Runway centreline lighting
  • Touchdown-zone lights
  • Enhanced runway edge lighting
  • Stop bars
  • Taxiway centreline lighting
  • Rapid power transfer
  • Monitoring and redundancy

Why maintenance focus matters

  • Serviceability
  • Redundancy
  • Fault detection
  • Rapid repair
  • Periodic testing
  • Photometric condition
  • Accurate asset records

Indian AIP information identifies serviceability restrictions for critical lighting during low-visibility operations at airports operating CAT II/CAT III procedures. Examples include operational restrictions linked to the unserviceability of approach lights, runway edge lights, centreline lights and touchdown-zone lights.[12] In low-visibility operations, unserviceable lighting can affect whether certain operations can continue. This creates additional requirements for design, power, controls, maintenance, testing and availability.

12 · Project Lifecycle

AGL Project Lifecycle, Site Survey & Design in India

A typical airport AGL project runs from requirement definition through operations and eventual rehabilitation. This lifecycle creates opportunities for specialist consultants, contractors, manufacturers and testing organisations at different stages.

Requirement Definition
Site Survey
AGL Design
Technical Specification
Tender / Procurement
Vendor Selection
Manufacturing / Supply
Civil Works
Cable Installation
Equipment Installation
Electrical Testing
Photometric Testing
Commissioning
DGCA / Authority Acceptance as Applicable
Operational Handover
Preventive Maintenance
Periodic Testing
Rehabilitation / Upgrade

Site survey

For rehabilitation projects, the survey should distinguish the existing as-built condition from the approved design requirement. This avoids designing an upgrade from inaccurate legacy drawings.

  • Runway coordinates and threshold coordinates
  • Runway dimensions and taxiway geometry
  • Existing lighting and cable infrastructure
  • CCR and transformer locations
  • Light-base condition
  • PAPI location / elevation
  • Existing control system and secondary power
  • Drainage and physical obstructions

AGL design coordinates

  • Optical: light locations, types, beam orientation, PAPI geometry, photometric requirements
  • Electrical: CCR selection, series circuits, cable sizing, transformers, connectors, voltage/current calculations
  • Control: local and remote control, ALCMS, monitoring, interlocks
  • Civil: foundations, ducts, trenches, drainage, light bases, pavement interfaces
  • Operational: runway availability, low-visibility procedures, switch-over, maintenance access, redundancy
13 · Rehabilitation & LED

AGL Rehabilitation & LED Upgrades in India

Many airports contain lighting equipment installed at different stages of airport development.

A rehabilitation project may involve
Old runway fixturesAging CCRsObsolete transformersDeteriorated cablesDamaged light basesOutdated control systemsInadequate documentationPoor photometric performance
A systematic rehabilitation programme
Condition Survey
Electrical Testing
Photometry
Failure Analysis
Design Review
Replacement Strategy
Implementation
Commissioning

This is generally more effective than replacing components solely based on age.

LED AGL upgrades

LED technology can provide reduced energy consumption, longer light-source life, reduced lamp replacement, improved reliability and improved monitoring. However, an LED upgrade should not be treated as a simple lamp replacement. The project should consider:

Optical compatibility
Colour and intensity
CCR compatibility
Isolation transformer compatibility
Circuit characteristics
Control system and monitoring
Photometric performance
Maintenance requirements

The complete system should be tested after the upgrade.

14 · Project Support & Documentation

Airport Lighting Project Support & Documentation

A full-service AGL engineering partner can support different project stages — and a professional project should produce a complete documentation package.

Strong documentation is particularly important for airport operators because it forms the basis for future maintenance.

15 · AGL Market Roles

AGL Consultants, Contractors, Manufacturers & Companies in India

The Indian AGL market is not made up of one type of company. These roles should not be confused.

RolePrimary Responsibility
ManufacturerDevelops and produces AGL equipment
SupplierProvides equipment / products
ConsultantDesigns / specifies / inspects / advises
ContractorInstalls and executes site works
Testing SpecialistMeasures / inspects / verifies performance
O&M ProviderMaintains the operating installation
Turnkey / SITC ContractorCombines several or all of these functions

Some companies cover multiple categories — for example, manufacturing, supply, installation, commissioning and maintenance — while others specialise primarily in photometry, testing and inspection. Both models can be useful depending on the project.

AGL consultants

An AGL consultant may support an airport project at the design, specification, tender, construction, inspection or commissioning stage.

  • AGL design — runway, taxiway, approach, PAPI, signs, CCRs, series circuits, cable design, control and monitoring
  • Technical specifications — equipment, performance, testing and acceptance criteria
  • Tender support — BOQ, technical schedules, compliance matrices, bid evaluation
  • Construction supervision — installation, cable and equipment inspection, alignment, quality control
  • Commissioning — test procedures, witness testing, photometry, final acceptance
  • Maintenance consultancy — programmes, condition assessment, rehabilitation planning, troubleshooting, asset management

AGL contractors

An AGL contractor may be responsible for supply, installation, testing and commissioning of airport lighting systems. Some Indian specialist contractors publicly describe capabilities spanning AGL installation, equipment supply, commissioning and maintenance.[8]

  • Civil works, foundations, cable trenches and ducting
  • Primary and secondary cables, transformers, connectors
  • Runway lights, taxiway lights, approach lighting, PAPI, signs
  • CCRs, control panels and ALCMS
  • Testing, photometry and commissioning
  • Maintenance

AGL manufacturers & suppliers

Evaluate suppliers by the specific product category and required approval, rather than treating "AGL manufacturer" as one uniform capability.[9]

  • Runway and taxiway lights, PAPI
  • CCRs and transformers
  • Connectors, cables, junction boxes, light bases
  • Signs
  • Control and monitoring systems

Indian businesses publicly describe capabilities across several of these categories. AMA, for example, describes design, supply, installation, commissioning, training and maintenance capabilities; Rewinder Techno Electricals describes AGL design, installation, commissioning and AMC services; Nasu Systems lists ALCMS, CCR, signs and other AGL products; and CTC Airfield describes installation and manufacturing of transformers, connectors and signage.[9][10]

A company that manufactures a runway light may not specialise in field photometry, PAPI alignment, cable testing, CCR troubleshooting or control-system commissioning. Likewise, a civil contractor may build foundations but lack specialist AGL electrical expertise. When comparing providers, identify the actual scope of technical responsibility. For complex airports, an integrated AGL team can reduce coordination gaps between design, equipment, installation, testing, commissioning and maintenance.

SITC AGL projects: Supply, Installation, Testing, Commissioning

Many airport projects are procured on an SITC basis, so the contractor may be responsible for the complete project chain — which requires much broader capability than simply supplying runway lights.

16 · Selection Guide

How to Select an AGL Consultant, Contractor or Supplier in India

The right partner should understand both airport operations and AGL engineering. The ideal capability covers Airport Operations + Electrical Engineering + Optical Performance + AGL Equipment + Commissioning.

Choosing a consultant

A consultant who understands only electrical engineering may not have sufficient airport visual-aid expertise; an airport specialist without detailed AGL electrical knowledge may not suit a technically complex lighting project.

  • ICAO visual-aid and DGCA aerodrome requirements
  • Runway, taxiway and approach lighting, PAPI
  • CCR systems, series circuits, AGL transformers
  • Photometry, testing and commissioning
  • Airport maintenance and technical specifications
  • Documentation: specifications, BOQs, drawings, test procedures, commissioning reports

Choosing a contractor

The strongest contractor is not necessarily the one offering the lowest initial supply price. AGL is safety-critical infrastructure, so lifecycle reliability matters.

  • Technical capability: can they install the complete system?
  • Product capability: can they supply compliant equipment?
  • Field resources: experienced airport technicians?
  • Testing capability: electrical testing, photometry, PAPI testing, commissioning
  • Maintenance capability: can they support the installation after handover?

Choosing a supplier

  • Product compliance with project and authority requirements
  • Manufacturing quality under a controlled system
  • Field experience at comparable airports
  • Factory and site testing capability
  • Datasheets, test certificates, manuals and drawings
  • Spare parts and technical support throughout equipment life
  • Long-term AMC or field service
Eight questions to ask before appointing a provider
1. What exactly do they provide?
Manufacturer, consultant, contractor, testing specialist or turnkey provider?
2. What airport experience do they have?
Ask for relevant project references.
3. Can they support commissioning?
Supply alone is not enough for a complex AGL project.
4. Can they provide photometry?
This can be important for both acceptance and long-term maintenance.
5. Can they support PAPI?
PAPI requires specialised optical and geometric expertise.
6. Do they understand the Indian regulatory environment?
Look for familiarity with applicable DGCA / ICAO / airport requirements.
7. Do they provide documentation?
Ask for datasheets, certificates, test reports, drawings, manuals and spare-parts lists.
8. Can they support the equipment after installation?
A supplier should ideally have a plan for Commissioning → Maintenance → Troubleshooting → Spare Parts → Long-Term Support.

17 · Airport Experience & Local Support

Why Airport Experience and Local Indian Support Matter

An AGL project is different from a conventional commercial lighting project.

Why airport experience matters

This is why airport experience should be one of the first criteria when selecting an AGL consultant or contractor.

  • Aircraft operations and runway safety
  • Airside access and visual guidance
  • Aerodrome standards
  • High-voltage series circuits
  • Photometry and PAPI geometry
  • Low-visibility operations
  • Maintenance constraints

Why local Indian support matters

Airport lighting projects can involve rapid response requirements — particularly operational airport maintenance, emergency faults, photometric surveys, PAPI alignment, troubleshooting and replacement projects.

  • Faster site attendance
  • Spare-parts availability
  • Local installation teams and technical support
  • Airport coordination experience
  • Easier AMC support
  • Reduced mobilisation time
18 · Compliance & Standards

Compliance and Standards for AGL in India

An Indian AGL project should be designed and delivered against the requirements actually applicable to that aerodrome.

DGCA

DGCA's CAR Section 4, Series B, Part I — Aerodrome Design and Operations forms an important part of the Indian aerodrome regulatory framework. The Ministry of Civil Aviation reported amendments to this CAR during 2025 to incorporate ICAO changes and address infrastructure-development requirements.[2]

ICAO

Relevant ICAO Standards and Recommended Practices provide the international foundation for aerodrome visual aids.

AAI

AAI's AIP publications provide airport-specific operational and infrastructure information, including runway lighting, taxiway lighting, PAPI, approach lighting and secondary power arrangements.[3]

Project specifications

Individual airport projects may impose additional technical requirements.

Manufacturer requirements

Equipment installation, commissioning and maintenance must also follow the applicable manufacturer's documentation.

The project-specific controlled documents determine the final acceptance requirement.

The strongest airport lighting partner is one that understands the complete lifecycle rather than only one product category. For airport operators, EPC contractors, consultants and project developers, the selection process should focus on technical competence, airport experience, compliant products, field testing capability, photometry, commissioning expertise and long-term support.

India's active airport development and maintenance environment demonstrates that AGL is an ongoing engineering requirement, not a one-time equipment purchase. Current AAI procurement includes AGL maintenance and specialist photometric testing, while Indian aerodrome information continues to document complex runway, taxiway, approach and PAPI installations.[1]

Design the system. Supply the right equipment. Test the installation. Verify the photometry. Maintain the airport lighting.

What standards apply to AGL projects in India?
Projects may be governed by the applicable DGCA aerodrome requirements, ICAO provisions, airport-specific specifications, project standards and equipment requirements. DGCA's CAR Section 4, Series B, Part I is a key Indian aerodrome regulatory reference, and the framework was amended during 2025.[2]
Why is photometry important for Indian airports?
Photometry provides measured evidence of optical performance and can identify low intensity, beam misalignment, colour issues and other deficiencies that may not be obvious during visual inspection.
Does AGL require maintenance after commissioning?
Yes. AGL is operational infrastructure and requires an ongoing programme covering inspection, cleaning, electrical testing, photometry, corrective maintenance and documentation.
Can the same company handle AGL design, supply, installation and commissioning?
Yes. Some AGL organisations provide multiple services, while others specialise in one stage such as photometry or equipment manufacturing. The appropriate model depends on the project procurement strategy.
What is SITC in airport lighting?
SITC generally refers to Supply, Installation, Testing and Commissioning. An SITC AGL contract can cover a complete project from equipment supply through final commissioning.
