What Is AGL Construction and Why Australian Airports Need It
AGL construction is a specialised field that is often misunderstood. This article explains what it involves and why Australian airports depend on qualified contractors to carry it out safely.
In aviation, AGL stands for Airfield Ground Lighting. It refers to the planning, installation, and commissioning of lighting systems that guide pilots safely during landing, take-off, and taxiing, particularly at night or in poor visibility. Airports across New South Wales, Queensland, and surrounding regions depend on this work to remain safe and legally compliant.
What Does AGL Construction Include?
Airfield ground lighting work covers the full scope required to build or upgrade a working airfield lighting system.
A typical project can involve:
- Runway edge, centreline, and threshold lighting systems.
- Taxiway lighting to direct aircraft between runways, aprons, and terminals.
- Apron floodlighting to illuminate ground handling areas.
- Underground cable and pit installation, including ducting beneath airfield pavements.
- Constant current regulator (CCR) installation and commissioning.
- Pilot Activated Lighting (PAL) systems, allowing pilots to switch on lights remotely via radio.
- Technical inspection and commissioning checks prior to operational use.
Each element must be designed and installed to precise standards, coordinated carefully around live aircraft operations.
What Regulatory Standard Governs AGL Construction in Australia?
Australian airfield lighting work must comply with CASA's Part 139 Manual of Standards (MOS 139). This mandatory standard sets out requirements for aerodrome lighting systems, including light intensities, colour coding, circuit design, and commissioning procedures.
MOS 139 also requires a formal commissioning process before a system is brought into service. This includes ground checks verifying light positions, alignments, and beam angles, and a flight check by a CASA-approved flight checker. Non-compliance can result in an aerodrome losing its certification to operate, making qualified airfield lighting contractors essential.
Which NSW and Queensland Airports Need AGL Work?
Regional airports in New South Wales and Queensland frequently require airfield lighting upgrades. Under the Federal Government's Regional Airports Programme, NSW airports including Kempsey and Griffith have received funding for lighting upgrades and PAL systems. In Queensland, airports from the Gold Coast to remote outback aerodromes regularly require new installations or system replacements as existing infrastructure ages.
Why Do Regional Airports Face Greater AGL Challenges?
Older infrastructure, tighter budgets, and exposure to heat, humidity, and storms accelerate wear on lighting circuits, cables, and fittings.
What Qualifications Should an AGL Contractor Hold?
It is mandatory for contractors to hold a current electrical contractors licence. They should also be able to demonstrate MOS 139 experience, and show a proven track record for operating on aerodromes.
Is AGL Construction Different From General Electrical Work?
Yes. Airfield systems use series-circuit wiring, constant current regulators, and aviation-specific fittings requiring specialist knowledge and strict airside safety compliance.
