Common Causes of Airfield Lighting Failures and How to Prevent Them

Airfield lighting is one of the most important parts of safe airport operations. It provides critical visual guidance for pilots during take-offs, landings, and taxiing, especially during night-time or poor weather conditions. However, like any system, airfield lighting can suffer from faults and failures. Knowing the common causes of these failures and how to prevent them is essential for keeping airfields safe and operational at all times.

One of the most common causes of airfield lighting failures is physical damage. Runway and taxiway lights are often located very close to aircraft movement areas. This puts them at constant risk of being hit by aircraft wheels, service vehicles, or maintenance equipment. Even a minor bump can knock lights out of alignment or cause internal damage that affects performance. Preventing this type of damage starts with good planning, including proper placement of lights and the use of low-profile, rugged designs. Regular staff training also helps ensure that everyone who operates vehicles near lighting systems understands how to avoid damaging them.

Weather-related damage is another major factor. Airfields in New Zealand face a wide range of tough conditions, including heavy rain, strong winds, and sudden temperature changes. Flooding can short-circuit underground wiring. Wind can cause poorly secured fixtures to shift or vibrate loose. Cold snaps followed by warming can cause water to seep into cracks and freeze, expanding and damaging fixtures. Good system design, including waterproof fittings, strong mounting systems, and regular inspections, helps protect against the worst effects of the weather.

Electrical faults are a further common cause of lighting failure. These can happen for many reasons, including worn cables, corroded connectors, and problems with power supplies. Sometimes faults are caused by age and wear, but sometimes they are made worse by poor installation practices. Using high-quality materials, installing systems carefully, and performing regular electrical testing greatly reduce the risk of unexpected failures. It is also important to have surge protection in place to defend against lightning strikes and power surges that can cause sudden system-wide outages.

Maintenance neglect is another factor that often leads to preventable failures. Lighting systems are often designed to run quietly in the background, which means that small faults can be easy to miss until they become big problems. Burnt-out bulbs, dimming LEDs, broken mounts, and dirty lenses all build up over time if regular maintenance is not performed. Having a clear, regular maintenance schedule that includes inspections, cleaning, and minor repairs keeps lighting systems working properly and extends their life.

Installation mistakes can also cause long-term problems. If lights are not aligned correctly during setup, they may not provide the right coverage or may cause glare that confuses pilots. If cables are not buried properly or if seals are not fitted tightly, water can get into the system and cause corrosion or shorts. Choosing experienced professionals who understand the specific needs of airfield lighting is key to getting an installation that performs well and avoids common mistakes.

Component ageing is another reality that every airfield must deal with. Even the best parts eventually wear out. Light output from even high-quality LEDs drops slightly over time. Plastic and rubber components become brittle with years of exposure to sunlight and weather. Electrical contacts oxidise and weaken. Keeping track of when systems were installed and planning for gradual upgrades helps avoid the sudden need for emergency replacements when parts finally fail.

Animal interference might seem unlikely, but it is a real problem at many airfields. Birds, insects, and even rodents can cause surprising damage to lighting systems. Birds sometimes nest on fixtures, blocking lights or damaging them with droppings. Rodents can chew through underground cabling, leading to electrical faults. Insect build-up inside fixtures can also block light output. Good design choices, including wildlife-resistant fittings and secure cabling, help prevent these kinds of issues from affecting system performance.

Human error is another risk that needs managing carefully. During routine maintenance or other airfield work, it is easy for workers to accidentally move or damage lighting components. Clear procedures, proper training, and good communication help reduce the chances of accidental damage. After any major works near lighting systems, it is also wise to perform extra inspections to make sure everything is still in perfect working order.

Power supply failures are a less common but very serious cause of lighting loss. If an airfield’s backup generators, battery systems, or main electrical feed fail, the entire lighting network can go dark in seconds. Having reliable backup systems, regularly tested and maintained, is essential. These backups need to be sized correctly to power critical lighting loads and must be ready to kick in automatically without delay.

Another cause of failures is outdated technology. Some older airfield lighting systems were not built with today’s traffic levels and safety expectations in mind. As demands have increased, older systems sometimes struggle to cope, leading to frequent faults or poor performance. Upgrading to modern LED lighting with better controls, stronger materials, and smarter monitoring systems helps ensure that airfields can meet current and future needs without unexpected outages.

Preventing airfield lighting failures is not about eliminating every risk. It is about managing risks wisely and being ready to respond quickly when problems arise. Regular inspections, good record-keeping, and proactive maintenance form the core of a strong lighting management plan. Investing in quality parts and professional installation also makes a big difference, reducing the chances of faults before they ever occur.

In the end, airfield lighting is about trust. Pilots trust that lights will guide them safely to the runway. Ground crews trust that taxiway lighting will show safe paths for moving aircraft. Emergency responders trust that apron lighting will help them reach people in need quickly. That trust is built on good maintenance, smart investment, and careful attention to every part of the lighting system.

Airfields that commit to strong lighting practices not only protect lives but also improve efficiency, avoid costly delays, and maintain strong reputations with airlines and the flying public. Good lighting is not an optional extra; it is a foundation for safe and reliable airfield operations.For professional help in preventing airfield lighting failures and keeping your systems operating at their best, trust the team at Up N Atom Electrical.

The Role of Airfield Lighting in Emergency Landings

Airfields are built to handle a wide range of situations, from routine flights to unexpected emergencies. One of the most important tools that supports safe landings, especially during emergencies, is a properly maintained and well-designed airfield lighting system. Airfield lighting provides critical visual guidance that pilots depend on when weather conditions are poor, visibility is low, or an urgent landing is required. Without it, even the most skilled pilots would face extreme difficulty getting their aircraft safely to the ground.

Emergency landings can happen for many reasons. Mechanical failures, medical emergencies, sudden weather changes, or fuel shortages all require pilots to react quickly and often land as soon as possible. In these high-stress situations, pilots must make fast decisions and rely heavily on clear visual cues from the ground. Airfield lighting systems guide pilots towards runways, highlight taxiways, show safe paths across the apron, and confirm when it is safe to land. If any part of the lighting system is missing, faulty, or hard to see, it increases the difficulty of an already tense situation.

Recently, I spoke with a pilot who had to perform an emergency landing at a rural airfield in bad weather. They described how the approach lighting system gave them the first clear indication that they were lined up with the correct runway. Even though the rain and wind made visibility poor, the strong and consistent lights allowed them to descend safely and avoid obstacles. Without reliable airfield lighting, this situation could have ended very differently. Stories like these highlight why airfield lighting is not just an extra feature but a vital part of emergency response.

Approach lighting is one of the first systems a pilot sees when coming in for a landing, especially during instrument approaches. A properly designed approach system provides a series of bright lights that extend out from the runway threshold, helping pilots line up accurately from a distance. In an emergency, when time and attention are limited, having a strong visual reference is crucial. It gives pilots confidence that they are on the right path and allows them to focus on controlling the aircraft instead of searching for the runway.

Runway edge lights, centreline lights, and threshold lights continue to guide the pilot through the final stages of landing. These lights outline the usable runway area clearly, showing where it begins and ends. If a plane is coming in low on fuel or has lost key instruments, these lights help ensure that the touchdown happens safely within the correct area. Even slight confusion about where the runway edges are can lead to dangerous outcomes, especially during night-time or poor weather landings.

Taxiway lighting is also important after the aircraft is safely on the ground. Emergency landings often require rapid response from ground crews, including fire and rescue services. Proper taxiway lights help pilots move the aircraft away from active runways and into safe areas where help can reach them quickly. Without clear taxi routes, aircraft could end up stuck or even collide with obstacles in the dark. Good lighting keeps everyone moving safely and efficiently during the critical minutes after an emergency landing.

Apron lighting ensures that when an aircraft reaches parking areas or emergency zones, there is enough visibility for crews to work quickly and safely. It allows ground teams to evacuate passengers if needed, assess any damage, and begin addressing technical problems without delay. Bright, even lighting reduces confusion and helps emergency teams do their jobs under pressure, whether it is attending to injured passengers, securing the aircraft, or clearing the runway for other operations.

Airfield lighting also supports coordination between pilots and air traffic control during emergencies. Controllers rely on the ability to activate specific lighting systems remotely to guide aircraft safely. They can turn on or adjust lights in response to changing conditions, helping pilots find the best and safest path. Having fully functional lighting that responds correctly when activated is crucial for this communication to work.

It is important to remember that not every airfield handles emergency landings daily. However, when emergencies do occur, airfields must be ready. Properly maintained lighting systems are a key part of that readiness. Routine inspections, fast repairs, and upgrades to modern LED lighting all help ensure that when an emergency happens, the airfield can provide the best possible support.

Airfields that invest in strong, reliable lighting systems not only improve daily operations but also build resilience for unexpected events. Pilots know which airports they can trust during bad weather or urgent situations. Airlines take note of airfields that maintain high standards of safety infrastructure. Communities surrounding regional airfields benefit too because they know that emergency flights, medical evacuations, and disaster responses can be handled safely when needed.

New Zealand’s varied weather conditions make strong airfield lighting even more important. Sudden fog, heavy rain, and strong winds are common challenges. A lighting system that can perform under these conditions protects both pilots and passengers. It also supports emergency services, allowing helicopters, fixed-wing aircraft, and air ambulances to land safely when every second counts.

Good lighting systems are not just about having bright lights. They are about having the right lights, in the right places, working correctly every time. Colour coding, spacing, intensity, and direction all play a role in guiding pilots accurately. Small mistakes in lighting design or maintenance can cause major confusion during emergencies. That is why it is essential to have experts involved in designing, installing, and maintaining airfield lighting.

Some airfields also install standby power systems to keep lighting active during blackouts or equipment failures. In an emergency, losing the runway lights can be catastrophic. Backup systems that automatically switch on if the main power fails provide an extra layer of security and peace of mind for pilots and ground teams alike.

Airfields that take lighting seriously show a commitment to safety, professionalism, and operational excellence. They demonstrate respect for the lives that depend on smooth operations during both normal and emergency conditions. Whether large or small, busy or quiet, every airfield plays a part in New Zealand’s transport and emergency networks, and strong lighting systems are at the heart of that responsibility.For expert advice, reliable upgrades, and professional maintenance of your airfield lighting systems, trust the team at Up N Atom Electrical. We are proud to help New Zealand’s airfields stay safe, ready, and resilient for whatever challenges may come.

Decoding the Lights: A Pilot's Guide to Airfield Illumination

Imagine hurtling through the night sky or dense fog. Below, a sprawling aerodrome awaits. How does a pilot navigate the final, critical stages of flight – the approach, landing, and taxiing – when visibility is limited? The answer lies in a complex, carefully orchestrated system of lights, often overlooked by passengers but utterly vital for safety: Airfield Ground Lighting, or AGL.

Far from being random decorations, these lights form a visual language, guiding pilots with precision and clarity. Let's delve into the world of AGL, understanding the different types of runway and taxiway lights and the crucial roles they play.

Defining the Landing Strip: Runway Edge Lights

Think of runway edge lights as the fundamental boundary markers. Their primary job is simple but essential: to outline the usable edges of the runway. For pilots lining up on approach or rolling out after touchdown, these lights clearly define the lateral limits of the paved surface they must stay within.

Typically, these are high-intensity, omnidirectional white lights visible from all angles around the aerodrome. However, their colour isn't uniform along the entire length. As a pilot approaches the departure end of the runway, the edge lights transition. On instrument runways, the last 600 metres (or the final third, whichever is less) feature yellow (or amber) lights instead of white.

This change serves as a visual cue, warning pilots they are nearing the runway's end – crucial information during takeoff or a landing rollout, especially on longer runways. Right at the very end, facing the direction of landing or take-off, they might appear red, indicating the absolute limit. The intensity of these lights can usually be adjusted by Air Traffic Control (ATC), cranking them up in poor visibility or dimming them on clear nights to avoid dazzling pilots.

Staying Straight: Runway Centreline Lights

While edge lights define the sides, runway centreline lights provide crucial directional guidance, helping pilots maintain alignment with the runway's central axis. This is particularly important during takeoff and landing, especially in low visibility conditions (LVC), where fog, heavy rain, or snow can obscure other visual cues.

These lights are embedded into the runway surface (inset lights) so aircraft can safely roll over them. They are spaced at regular intervals (typically 15 or 30 metres apart, depending on the runway category). Their colour coding provides pilots with valuable information about their position along the runway.

For most of the runway length, they are white. As the aircraft nears the end, the pattern changes. From 900 metres down to 300 metres from the end, the lights alternate between red and white. For the final 300 metres, they become solid red, providing an unmistakable warning that the end of the paved surface is rapidly approaching. This coding helps pilots judge their remaining distance for braking after landing or deciding whether to abort a takeoff.

Marking the Gateway: Threshold and Runway End Lights

Every journey needs a clear beginning and end, and runways are no different. Specialised lights mark these critical points.

Threshold Lights: These mark the very beginning of the landing area. They appear as a distinct bar of green lights, shining unidirectionally towards the approaching aircraft. Seeing this solid green bar confirms the pilot is correctly aligned with the start of the designated landing surface. Crossing this threshold signifies the transition from approach to the landing flare and touchdown.

Runway End Lights (REL): Conversely, these mark the absolute end of the runway. They consist of a bar of red lights, also unidirectional, but facing back down the runway towards an aircraft that has landed or is taking off. They serve as a final visual stop sign, warning pilots not to proceed beyond this point.

Together, the green threshold lights and red end lights clearly demarcate the longitudinal limits of the runway available for landing and takeoff operations.

Pinpointing the Landing: Touchdown Zone Lights

In addition to marking the start, specific lights help pilots identify the ideal landing area – the Touchdown Zone (TDZ). These are inset white lights arranged in rows (barrettes) symmetrically about the runway centreline. They typically extend from the landing threshold for about 900 metres down the runway.

Their purpose is to provide enhanced visual cues for depth perception and positioning during the final moments before touchdown, guiding the pilot to land within this designated, structurally optimal part of the runway. In low visibility, they become particularly important for confirming the aircraft is in the right place just before the wheels make contact.

Nailing the Approach: Visual Slope Guidance

Before even reaching the threshold, pilots need confirmation they are descending correctly. This is where visual approach slope indicator systems come in, the most common modern system being the Precision Approach Path Indicator (PAPI).

PAPIs are usually located on one side of the runway (typically the left), near the touchdown point. They consist of a row of four light units, appearing as either red or white depending on the aircraft's vertical position relative to the ideal glide slope (usually 3 degrees). The combination of colours tells the pilot instantly whether they are too high, too low, or perfectly on the glide path:

Four White: "Flying high in the white sky" – You are significantly too high.

Three White, One Red: You are slightly too high.

Two White, Two Red: "Two white, two red, you're alright" – You are on the correct glide slope. This is the target indication.

One White, Three Red: You are slightly too low.

Four Red: "Red means dead (if you don't correct!)" – You are significantly too low.

These simple, unambiguous signals allow pilots to make immediate corrections to their descent rate, ensuring a safe and stable approach towards the touchdown zone, complementing their instrument readings with a direct visual reference. (Older systems like VASI – Visual Approach Slope Indicator – existed, often using two bars of lights, but PAPI is the modern standard).

Guiding Off the Runway: Taxiway Lighting

Once an aircraft has safely landed and slowed down, or when it's preparing for departure, it needs to navigate the network of taxiways connecting the runway to the gates, aprons, and maintenance areas. Taxiway lighting ensures this ground manoeuvring happens safely, preventing confusion and potential collisions, especially at complex airports or during nighttime/LVC operations.

Taxiway Edge Lights: Similar to runway edge lights, these define the lateral limits of the taxiway. However, they are distinctly blue in colour. This immediate colour difference ensures pilots can easily distinguish between a taxiway and a runway, preventing potentially catastrophic errors like attempting to take off or land on a taxiway. These blue lights stand like little sentinels guiding the aircraft along the correct path.

Taxiway Centreline Lights: On major taxiways, particularly those used in low visibility conditions, green centreline lights are installed. Much like their runway counterparts, these are inset into the pavement and provide directional guidance, helping pilots accurately follow the taxi route designated by ATC. At complex intersections, they may be supplemented with stop bars (red lights indicating a mandatory hold point) and clearance bars (yellow lights indicating an upcoming intersection).

A Symphony of Safety

The array of lights on an airfield is far more than just illumination. It's a sophisticated, internationally standardised language designed for clarity and safety. From the moment a pilot begins their approach until the aircraft is safely parked, these lights provide continuous, vital information about position, alignment, distance, and clearance. Runway edge lights, centreline lights, threshold and end lights, touchdown zone lights, PAPIs, and the distinct blue and green of taxiway lights all work together in a carefully orchestrated system. Controlled by ATC and designed to be effective in all weather conditions, day and night, airfield ground lighting remains one of the most critical, yet often unappreciated, elements ensuring the safety and efficiency of modern air travel.

They are the silent guardians guiding pilots safely between the sky and the ground.

Keeping the Lights On: An Essential Blueprint for Airfield Lighting Maintenance in New Zealand

The intricate network of lights bordering runways, guiding aircraft along taxiways, and illuminating approach paths form the silent language of airfield operations. These guiding beacons – the Airfield Ground Lighting (AGL) system – are utterly critical, especially when darkness falls or visibility drops. They are non-negotiable safety elements, ensuring pilots can navigate complex ground environments accurately and land safely.

But like any critical infrastructure, AGL systems demand consistent, meticulous care to perform reliably. Simply waiting for a light to fail isn't an option; a proactive, preventative maintenance programme is the cornerstone of ensuring safety, compliance, and operational efficiency at any New Zealand airport. This isn't just about ticking boxes; it's about fostering a culture of vigilance for these vital assets.

Why Proactive Care is Non-Negotiable

Investing time and resources into a structured preventative maintenance (PM) programme for AGL systems yields significant returns far beyond simply keeping the lights on. The benefits are clear and compelling:

Enhanced Safety: The primary goal. Regular checks and maintenance identify potential failures before they happen, preventing situations where pilots might receive ambiguous or incorrect visual cues during critical flight phases. This directly mitigates risks like runway incursions or excursions.

Assured Compliance: The New Zealand Civil Aviation Authority (CAA), aligned with international ICAO standards, mandates specific performance criteria for AGL systems. A documented PM programme, including regular testing and inspections, provides crucial evidence of compliance during audits, ensuring the airport maintains its operating certification.

Improved Operational Efficiency: Unexpected AGL failures can cause significant disruptions – runway closures, taxiway restrictions, flight delays, and diversions. Proactive maintenance minimises these costly interruptions, helping the airport maintain smooth operations and throughput.

Extended Asset Life: AGL systems represent a substantial investment. Regular cleaning, inspection, and timely minor repairs prevent small issues from escalating into major failures, protecting the equipment from premature degradation and extending its operational lifespan.

Long-Term Cost Savings: While PM requires upfront resources, it is significantly more cost-effective than reactive maintenance. Preventing major component failures avoids expensive emergency repairs and replacement costs. Furthermore, well-maintained systems (especially regarding cleanliness) operate more efficiently.

Laying the Groundwork: The Power of Regular Inspections

Consistent, observant inspection is the foundation of any effective AGL maintenance programme. It's about developing a keen eye for the tell-tale signs of potential problems. Inspection schedules should be layered, combining frequent quick checks with more in-depth examinations:

Daily Checks (Often Operational Staff): A quick visual scan during daylight hours or operational shifts. Focus on obvious damage (e.g., broken lenses after potential impact), lights clearly out (if the system allows reporting), and any obstructions or Foreign Object Debris (FOD) near fittings.

Weekly/Monthly Checks (Maintenance Team): More detailed visual and physical checks. This involves walking or slowly driving the circuits. Key areas include:

Light Fittings (Runway, Taxiway, Approach, PAPI/VASIS, Signage): Check for physical integrity – cracks, chips, and signs of impact. Ensure secure mounting; loose fittings are vulnerable. Look for condensation or water ingress inside lenses. Check for signs of corrosion on housings and fastenings, a particular concern in New Zealand's coastal environments. Verify correct alignment (especially for directional lights like runway edge or PAPI units).

Lenses & Filters: Assess clarity and cleanliness (more on cleaning below). Check for discolouration or degradation.

Cabling & Connections: Look for any exposed wiring, damage to conduits protecting cables, or signs of rodent activity. Check the security and condition of plugs and connectors, including airfield lighting transformers, if accessible (looking for pitting, corrosion, or overheating signs).

Illuminated Signage: Verify correct illumination, legibility of panels, and physical condition of the sign structure.

Surrounding Area: Check for vegetation growth obstructing lights, ensure drainage around in-pavement lights is clear to prevent water pooling and remove any accumulated FOD.

Quarterly/Annual Checks (In-depth): This may involve closer examination, potentially requiring brief circuit shutdowns for safety. Includes checks inside accessible pits or transformer housings, torque checks on fastenings, and can be coordinated with electrical testing.

Crucially, every inspection, no matter how brief, must be documented. Consistent records track the condition of assets over time, highlight recurring issues, inform maintenance priorities, and provide vital proof of diligence for compliance purposes.

A Clear View: The Essential Task of Cleaning

It sounds basic, but the impact of dirt, grime, rubber deposits (especially near touchdown zones), salt spray, and other contaminants on AGL performance cannot be overstated. A layer of dirt can significantly reduce light output (intensity), potentially rendering a technically functional light non-compliant with photometric standards.

It can also subtly alter the perceived colour of the light, which is critical for pilot interpretation. Accumulated grime can also trap heat, potentially shortening the life of components.

Therefore, regular, methodical cleaning is a non-negotiable maintenance task:

What to Clean: Focus primarily on the light-emitting surfaces – the outer lenses of runway, taxiway, and approach lights, PAPI/VASIS lenses/filters, and the faces of illuminated guidance signs. Reflectors, if present and accessible, should also be cleaned.

How and When: Use appropriate cleaning agents that won't scratch or damage the lens material (often specified by the manufacturer). Soft cloths or brushes are typically recommended. The frequency depends heavily on the airport's location and operational tempo. Lights in touchdown zones, near taxiway exits, or in coastal areas exposed to salt spray will require more frequent cleaning than those in less contaminated areas. Cleaning should be integrated into the regular inspection schedule.

Verifying Performance: Essential Testing Procedures

Visual inspections and cleaning are vital, but they don't tell the whole story. Regular testing is required to confirm the system is functioning correctly and meeting the required performance standards:

Operational & Functional Tests: These checks ensure the system operates as intended from the control perspective.

Control System Checks: Regularly verify that all circuits switch on and off correctly from the control tower or maintenance interface. Test the different intensity settings (brightness levels) to ensure they are functioning as expected.

Interlocking Systems: Test any safety interlocks, such as those connecting stop bar lights to runway status or other control inputs.

Backup Power Tests: Critically important. Simulate a primary power failure to confirm the secondary power supply (generator or UPS) starts automatically and takes the AGL load within the specified time limit (often mere seconds). Test the duration capability of the backup system periodically.

Photometric Testing: This is the quantitative measurement of light output. Specialised equipment is used (often mobile) to measure the actual intensity (candela), beam pattern, and colour coordinates of the light emitted by installed fixtures.

Why it's Crucial: It's the only definitive way to know if a light, even if illuminated, meets the strict intensity and colour requirements mandated by the CAA. It identifies degradation invisible to the naked eye and confirms compliance after installation or major maintenance.

Frequency: Often conducted annually, after major repairs/replacements, or as required by regulatory oversight.

Electrical Testing: These tests assess the health and safety of the electrical circuits powering the AGL system.

Insulation Resistance Tests: Measures the integrity of the cable insulation between conductors and earth. Low readings can indicate insulation breakdown, posing a safety risk and potentially leading to circuit failure, especially in wet conditions.

Earth Resistance Tests: Verifies the effectiveness of the system's safety earthing (grounding), crucial for protecting personnel and equipment during fault conditions.

Circuit Load/Current Checks: Measures the current flowing in each circuit. This helps identify imbalances, overloaded circuits, or faulty components drawing incorrect current.

Beyond the Basics: Rounding Out the Programme

A truly comprehensive PM programme includes a few more key elements:

Proactive Component Replacement: Don't wait for failure. Implement schedules for replacing components with known lifespans, such as halogen lamps based on hours run, or even anticipating LED module replacement towards the end of their very long rated life. Seals and gaskets should also be replaced periodically to maintain water tightness.

Calibration: Ensure all test equipment (photometers, electrical testers) is regularly calibrated according to manufacturer recommendations to guarantee accurate measurements. Critical systems like PAPI/VASIS also require periodic calibration, often involving flight checks or specialised ground measurements.

Meticulous Record Keeping & Analysis: As mentioned, documentation is key. But don't just file the records – analyse them! Use the data from inspections and tests to spot trends (e.g., recurring faults on a specific circuit), predict potential failures, justify budget requests for upgrades, and continuously refine the maintenance programme itself. These records are also essential for demonstrating compliance.

Technician Training & Qualification: Ensure the personnel performing AGL maintenance are properly trained, qualified, and equipped with the right tools and knowledge of safety procedures for working airside and with electrical systems.

Tailoring Your Approach

While this outlines essential tasks, the specific frequency and intensity of each activity should be tailored to the individual airport. Factors like the type of lighting installed (LED systems generally require less frequent intervention than halogen), the volume of air traffic, local environmental conditions (coastal salt, industrial pollution, extreme weather), and regulatory requirements will all influence the final shape of the maintenance checklist and programme.

It should be a dynamic document, reviewed and updated based on experience and changing conditions.

Investing in Reliability and Safety

Maintaining an airfield ground lighting system is far more than just replacing bulbs. It's a continuous cycle of diligent inspection, thorough cleaning, rigorous testing, and proactive care. A well-executed preventative maintenance programme, built around a comprehensive checklist and meticulous record-keeping, is not an expense – it's a fundamental investment.

It’s an investment in the safety of flight crews and passengers, in the operational reliability that keeps New Zealand connected, in the longevity of critical airport infrastructure, and in the unwavering compliance that underpins public confidence in aviation.

The Future is Bright: Why LED Technology is Transforming New Zealand's Airfield Lighting

For decades, the familiar warm glow of halogen lamps has reliably illuminated runways and taxiways at airports across New Zealand and the world. These lights, the unsung heroes of night-time and low-visibility operations, provide the critical visual cues pilots depend upon for safe navigation.

However, technology rarely stands still. Just as incandescent bulbs in our homes have largely given way to more efficient alternatives, the world of Airfield Ground Lighting (AGL) is undergoing a profound transformation, driven by the compelling advantages of Light Emitting Diode (LED) technology. For airport operators in New Zealand, the decision is no longer if they should consider switching from traditional halogen systems but when and how to embrace this brighter, more efficient future.

The Era of Halogen: A Familiar Workhorse Reaching its Limits

Traditional halogen AGL lamps have served the aviation industry well. Based on incandescent technology, they work by passing electricity through a tungsten filament within a halogen gas-filled bulb, producing light and significant heat. They established the standards for airfield illumination and, for a long time, were the only viable option. Their initial purchase cost is relatively low, and the technology is well-understood by maintenance crews globally.

However, halogen lighting comes with inherent drawbacks that are becoming increasingly significant in today's world. They are notoriously energy-inefficient, converting a large portion of electrical energy into heat rather than useful light. This translates directly into higher electricity bills for airports. Their operational lifespan is relatively short – typically ranging from 1,000 to 2,000 hours – meaning frequent replacements are necessary.

This constant need for maintenance involves not only the cost of new lamps but also significant labour costs, potential operational disruptions during lamp changes (requiring parts of the airfield to be closed), and the safety considerations of staff working airside. Furthermore, the light output of halogen lamps degrades noticeably over their lifespan, potentially compromising visibility consistency.

Enter LED: A Revolution in Airfield Illumination

LED technology operates on a completely different principle. It uses semiconductors to convert electricity directly into light, a process known as electroluminescence. This method is vastly more efficient, produces far less heat, and allows for precise control over the light's colour and directionality. Initially expensive and limited in application, LED technology has matured rapidly, becoming robust, reliable, and increasingly cost-effective, making it an ideal solution for the demanding environment of an airfield.

Head-to-Head: Where LED Clearly Outshines Halogen

When comparing LED AGL systems to their traditional halogen counterparts, the advantages of modern technology become starkly apparent across several key areas:

Power Play: Unlocking Dramatic Energy Savings This is perhaps the most cited benefit of LED technology. LEDs consume significantly less power than halogen lamps to produce the same amount of light – often achieving energy savings of 50% to 80% or even more, depending on the specific application and fixture. For an airport running thousands of lights, often 24/7 or for extended periods, this translates into substantial reductions in annual electricity costs. In the context of New Zealand's commitment to sustainability and reducing carbon emissions, this energy efficiency aligns perfectly with national environmental goals. Lower energy consumption means a smaller carbon footprint, contributing to greener airport operations.

Built to Last: Exceptional Lifespan and Reliability The difference in operational life is staggering. While halogen lamps might last 2,000 hours at best, LED fixtures commonly boast lifespans exceeding 50,000 hours, with many rated for 100,000 hours or more. This longevity drastically reduces the frequency of replacements. Imagine changing a bulb once every decade or two instead of multiple times a year! This reliability is further enhanced by the physical nature of LEDs. They have no fragile filament susceptible to vibration or shock – a significant advantage in the airfield environment, particularly relevant in seismically active regions like parts of New Zealand or where ground vibrations from heavy aircraft are common. This inherent robustness means fewer unexpected failures and greater system dependability.

Slashing the Burden: Significantly Lower Maintenance Costs The extended lifespan of LEDs directly translates into dramatically reduced maintenance requirements. Fewer lamp replacements mean lower expenditure on spare parts and consumables. More importantly, it significantly cuts down on the labour hours needed for maintenance crews to perform replacements. Accessing airfield lighting often requires closing runways or taxiways, impacting airport capacity and potentially causing delays. Reducing the frequency of these interventions enhances operational efficiency and safety, minimising the time staff need to spend working in potentially hazardous airside areas. The reduced need for lamp inventory also simplifies logistics and storage.

Sharper Vision: Superior Performance and Visibility LEDs offer tangible improvements in light quality and performance. Unlike halogens, which can dim and yellow over time, LEDs maintain a consistent light intensity and stable colour output throughout their long lifespan. This ensures pilots receive reliable visual cues every time. LEDs can be engineered to emit light within very precise colour coordinates, easily meeting the strict chromaticity standards set by the CAA and ICAO for signal colours (red, green, yellow, white). The light produced is often perceived as crisper and clearer, enhancing visual acuity. Furthermore, LED optics allow for highly controlled beam patterns, directing light precisely where needed (e.g., onto the runway or taxiway) and minimising stray light or glare, which contributes to reducing light pollution. They also offer instant 'on' capabilities at full brightness without the warm-up time sometimes associated with older technologies. For pilots operating in New Zealand's diverse weather – from clear nights to coastal fog or driving rain – this consistent, high-quality illumination can make a critical difference in perception and safety.

Weighing the Investment: Beyond the Initial Price Tag

It's true that the initial purchase price of LED AGL fixtures is typically higher than that of traditional halogen units. However, viewing this cost in isolation is misleading. When considering the Total Cost of Ownership (TCO), the financial argument swings heavily in favour of LEDs. The substantial savings generated through drastically reduced energy consumption and minimal maintenance requirements over the extended lifespan of the LED system often result in a compelling Return on Investment (ROI), typically realised within just a few years. Airports need to look beyond the upfront capital expenditure and analyse the long-term operational savings.

Furthermore, while some older infrastructure, like Constant Current Regulators (CCRs), might require assessment or upgrading to be fully compatible or optimised for LED loads, many modern LED AGL fixtures are designed as 'plug-and-play' replacements, minimising infrastructure changes. Integration with existing control systems is also a key consideration during planning.

The New Zealand Advantage: Aligning with Local Priorities

For New Zealand airports, the switch to LED AGL resonates strongly with local conditions and priorities. The energy savings directly support national climate change objectives and can enhance an airport's environmental credentials. The robustness of LEDs makes them well-suited to variable weather conditions, including wind and rain, and their reliability is an asset in maintaining operational continuity. The reduced light pollution potential is also a growing consideration for environmentally conscious planning.

Navigating the Upgrade: A Planned Transition

Making the switch from halogen to LED requires careful planning. Airports might opt for a phased rollout, perhaps upgrading specific circuits or areas (e.g., a particular taxiway or runway) as part of scheduled maintenance or larger refurbishment projects. Alternatively, a full-scale replacement programme might be undertaken. Key steps include selecting reputable suppliers whose products meet the stringent CAA certification requirements, ensuring compatibility with existing infrastructure or planning necessary upgrades, and managing the installation process to minimise operational disruption.

Illuminating a Smarter Path Forward

The transition from traditional halogen to LED airfield ground lighting represents a significant technological leap forward, offering a compelling suite of benefits that are hard to ignore. While halogen lamps have served their purpose, LED technology provides undeniable advantages in energy efficiency, lifespan, reliability, maintenance reduction, and light quality. The lower total cost of ownership, coupled with enhanced safety and performance, makes LED the clear choice for future-focused airports.

For New Zealand airports aiming to optimise operations, reduce environmental impact, enhance safety, and make sound long-term financial decisions, embracing LED AGL technology is not just an upgrade – it's a strategic investment in a brighter, more sustainable, and more efficient future for aviation. The evidence points clearly towards LED as the new standard, lighting the way forward for airfields across the country.

Shining a Light on Safety: The Indispensable Role of CAA-Compliant Airfield Lighting in New Zealand Aviation

Imagine hurtling through the night sky or descending through thick fog towards a destination. Below, amidst the darkness or gloom, a pattern of lights emerges – a carefully orchestrated visual language guiding the aircraft safely towards the ground. These aren't just random illuminations; they are part of a complex Airfield Ground Lighting (AGL) system, arguably one of the most critical safety components of any modern airport.

In New Zealand, where weather can change rapidly and terrain can be challenging, the reliability and precision of AGL systems are paramount. Ensuring these systems adhere strictly to the standards set by the New Zealand Civil Aviation Authority (CAA) is not merely a regulatory hurdle; it's fundamental to safeguarding lives, maintaining operational efficiency, and upholding the integrity of the nation's aviation network.

The importance of flawlessly functioning, compliant AGL cannot be overstated. It serves as the primary visual aid for pilots during night operations and periods of low visibility, providing essential cues for approach, landing, rollout, and taxiing.

Without this guidance, the risk of serious incidents increases dramatically. The CAA, as the governing body for aviation safety in New Zealand, establishes comprehensive regulations and guidelines that dictate exactly how these lighting systems must perform. Understanding these requirements and the mechanisms for ensuring compliance is crucial for every airport operator.

More Than Just Lights: The Pillars of Safety and Operational Integrity

The mandate for CAA-compliant AGL stems from its direct impact on two core pillars: aviation safety and operational efficiency. Let's delve deeper into why these standards are so critical.

Enhancing Flight Safety:

Preventing Runway Incursions and Excursions: Properly functioning runway edge lights, centreline lights, threshold lights, and taxiway lighting provide unambiguous guidance, significantly reducing the risk of aircraft straying from designated paths. Clear demarcation helps prevent runway incursions (unauthorised presence on a runway) and excursions (veering off the runway during landing or take-off). Taxiway centerline and edge lights, along with stop bars at runway holding points, are vital for guiding aircraft safely between the runway and the apron, especially in complex airfield layouts or poor visibility.

Aiding Approach and Landing Precision: Systems like the Precision Approach Path Indicator (PAPI) or its predecessor, VASIS, provide pilots with crucial vertical guidance on the final approach. Approach Lighting Systems (ALS) extend outwards from the runway threshold, helping pilots align the aircraft horizontally and transition from instrument flight to visual flight rules just before touchdown. The correct intensity, configuration, and colour of these lights are vital for accurate perception and decision-making during this critical flight phase. Malfunctioning or non-compliant approaches and landing aids could lead to unstable approaches, hard landings, or worse.

Enabling Low Visibility Procedures (LVP): During fog, heavy rain, or snow, visibility can drop significantly. Compliant AGL, often operating at higher intensity settings and potentially including systems like runway centreline lights and touchdown zone lighting (if installed), becomes even more critical. It allows airports to continue operating safely under conditions that would otherwise necessitate closures or diversions, relying on the lights to provide the visual cues instruments alone cannot fully replicate.

Reducing Pilot Workload: Consistent, standard-compliant lighting reduces ambiguity and cognitive load on flight crews, particularly during high-stress situations like adverse weather or emergencies. Knowing the lighting configuration meets expected standards allows pilots to interpret the visual cues quickly and accurately.

Maintaining Operational Efficiency:

Maximising Airport Capacity: Reliable AGL allows airports to operate closer to their maximum capacity during night-time hours and poor weather conditions. Without dependable lighting, capacity would significantly decrease, leading to bottlenecks in the aviation system.

Minimising Delays and Diversions: Faulty or non-compliant lighting can lead to temporary runway closures or restrictions, causing flight delays and potentially costly diversions for airlines. Consistent compliance ensures the airfield remains available, contributing to on-time performance and passenger satisfaction.

Supporting Economic Activity: Airports are vital economic hubs. The ability to operate reliably around the clock, facilitated by effective AGL, supports tourism, trade, and business connectivity. Disruptions due to inadequate lighting have tangible economic costs.

The Guiding Hand: Understanding CAA Standards for AGL

The CAA's requirements for AGL are detailed and comprehensive, primarily outlined within Civil Aviation Rule Part 139 (Certification of Aerodromes) and supported by Advisory Circulars (ACs), such as AC139-6, which provides detailed guidance on Aerodrome Lighting. These rules aren't arbitrary; they are based on international standards set by the International Civil Aviation Organization (ICAO), ensuring harmonisation and predictability for flight crews arriving from anywhere in the world. The core principle is risk management – ensuring the lighting systems mitigate the risks associated with operating aircraft in varying conditions.

Key areas covered by CAA standards include:

Specific Lighting System Requirements:

Approach Lighting Systems (ALS): The configuration (e.g., Calvert, ALSF-1/2), intensity settings (adjustable for conditions), and alignment tolerances are precisely defined.

Runway Edge Lights: Must be white, except for caution zones (yellow) near the departure end, and spaced according to runway category. Their beam must be angled correctly for optimal visibility on approach and along the runway.

Runway Threshold and End Lights: Threshold lights are green (facing the approach) and runway end lights are red (facing the runway), clearly marking the usable runway limits.

Runway Centreline and Touchdown Zone Lights (TDZL): Typically required for higher precision runways, these lights provide critical alignment guidance. Centreline lights are colour-coded (white, then alternating red/white, then red) to indicate the distance remaining. TDZL provides distance information in the landing area.

Taxiway Lighting: Blue edge lights and/or green centreline lights guide aircraft on taxiways. Red stop bars are used at runway holding points and are interlocked with air traffic control procedures.

PAPI/VASIS: Must provide accurate visual glide slope information within tight tolerances. Regular flight checks and ground calibration are essential.

Obstruction Lights: Required on tall structures near the airport to ensure they are visible to pilots.

Signage: Illuminated guidance signs must be clearly legible and conform to standard layouts.

System Performance and Reliability:

Photometric Performance: This relates to the brightness (intensity), colour coordinates (within specific CIE boundaries), and beam spread of each light. Lights must meet specified photometric standards when new and throughout their operational life. Regular photometric testing is becoming increasingly important.

Electrical System Integrity: The power supply must be reliable, often requiring backup power sources (secondary power supply) capable of switching over automatically and quickly (typically within 15 seconds, often faster for critical systems) in case of a primary power failure. Circuitry must be designed to minimise the impact of single-point failures.

Maintenance and Inspection: The CAA mandates regular inspection and maintenance programmes. This includes visual checks, cleaning of lenses, preventative replacement of lamps or LED modules, and functional tests of the entire system, including control and monitoring components. Detailed records must be kept.

Control and Monitoring: Systems must allow air traffic control or relevant personnel to select appropriate lighting configurations and intensities and ideally, provide feedback on the operational status of the lights.

Bridging the Gap: Achieving and Maintaining Compliance with Expert Support

For airport operators, meeting these extensive CAA requirements is a significant undertaking. It demands specialised knowledge, ongoing investment, and rigorous processes. The complexity of modern AGL systems, combined with the absolute necessity for reliability, means that expertise is not just beneficial – it's essential. This is where specialist AGL service providers like Up 'n' Atom play a crucial role.

This involves careful cable laying, correct fixture mounting and alignment, transformer connections, and integration with control systems, all performed to minimise disruption to airport operations.

Rigorous Commissioning and Verification: Before a new or refurbished system goes live, undertake comprehensive testing. This isn't just flipping a switch; it involves detailed photometric measurements to verify light output and colour, electrical testing of circuits and insulation resistance, checking backup power functionality, and confirming control system responses – all benchmarked against CAA standards.

Proactive Maintenance Programmes: Developing and executing tailored maintenance schedules. This goes beyond fixing things when they break; it involves regular visual inspections, thorough cleaning of lenses and filters (crucial for light output), periodic re-lamping or replacement of LED light engines based on expected life, torque checks on fastenings, and functional testing. The goal is preventative – addressing potential issues before they cause outages or non-compliance.

Responsive Corrective Maintenance: Providing rapid support when faults inevitably occur. This requires skilled technicians capable of quickly diagnosing issues (which could be anything from a burnt-out lamp to a complex control system fault) and implementing effective repairs to restore full compliance with minimal downtime.

Why High-Quality Airfield Lighting is a Game-Changer

As an electrician, I’ve worked on everything from home wiring to massive commercial projects, but airfield lighting is on a whole different level. When dealing with a system that pilots depend on for safe landings and takeoffs, there’s no room for shortcuts. It’s not just about making a runway visible; it’s about precision, safety, and efficiency.

Too many airfields struggle with flickering runway lights, outdated systems, and costly maintenance issues. Some still rely on old halogen setups that drain energy and require constant replacements. Others have misaligned lighting that doesn’t provide clear guidance, which can be risky in poor visibility. These aren’t just minor inconveniences; they’re real hazards that affect every aircraft coming in and out.

A pilot landing at night or in bad weather isn’t relying on streetlights or floodlights; they need precisely installed and placed airfield lighting to guide them safely. Runway edge lights, taxiway markers, and approach lights ensure clear visibility and proper alignment. If just one section of the lighting fails, it can throw off depth perception and judgment, making landings far more dangerous.

Airfield lighting needs to be consistent, reliable, and easy to maintain. I’ve seen cases where lighting systems weren’t properly calibrated, causing dark patches or overly bright sections that distorted pilots’ views. Small issues like this might not seem like a big deal to the average person, but they make all the difference for someone flying in with low visibility.

The biggest change in airfield lighting right now is the shift to LED systems, and for good reason. Old-school incandescent and halogen lights burn out too quickly, consume too much power, and require constant maintenance. LED lighting fixes all of that.

LED airfield lights are brighter, more durable, and use less energy. They don’t overheat like traditional bulbs, which extends their lifespan, and they provide better visibility in fog, rain, and snow. Many airports and private airstrips also adopt smart lighting systems, which automatically adjust brightness based on real-time conditions, making operations even safer and more efficient.

I’ve worked with airfields that tried to delay lighting upgrades to save money, but the reality is that patchwork repairs and outdated systems cost more in the long run. Poor lighting means higher maintenance costs, more energy consumption, and increased risks of failures. And when an airfield experiences a lighting failure at the wrong time, it can cause flight delays, safety concerns, or even shutdowns.

One of the worst things I’ve seen is airfields trying to make do with DIY fixes or hiring inexperienced electricians to handle runway lighting. This isn’t your average wiring job. It requires precise installation, proper voltage control, and strict compliance with aviation safety standards. A misstep could lead to uneven illumination, poor visibility, or even system-wide malfunctions.

The best airfields don’t just install lighting and forget about it; they invest in high-quality systems, regular maintenance, and expert installation. You create a safe and efficient environment for pilots, ground crews, and airport operations.

If you’re managing an airfield and haven’t yet switched to modern, energy-efficient lighting, now is the time. The benefits are obvious: lower energy costs, fewer maintenance headaches, and, most importantly, safer conditions for every flight.

From experience, I can tell you this: cutting corners on airfield lighting is never worth it. Proper lighting is non-negotiable, whether it’s a major airport or a small private strip. Investing in the right system today means fewer problems, lower costs, and safer skies for everyone.

Why Hiring a Professional for Airfield Lighting Was the Best Decision

I’ve always enjoyed tackling small DIY projects, whether fixing things around the house, assembling furniture, or handling basic maintenance. But when it comes to electrical work, I know better than to take risks especially in critical environments like airfields, where precision and safety are everything.

When I noticed inconsistent illumination on the runway, flickering lights along the taxiways, and a strange buzzing sound from the lighting control system, I knew it was time to call in a professional electrician. Initially, I thought about troubleshooting the issue, but looking back, I’m so glad I left it to the experts.

At first, I assumed checking a few connections or replacing a couple of bulbs would fix the issue. But after researching, I quickly realised that airfield lighting is not something to take lightly.

For starters, high performance airfield lighting systems are complex. They must function flawlessly in all weather conditions, providing pilots with the visibility and guidance required for safe takeoffs and landings. A single wiring issue or voltage inconsistency could result in dimmed or unreliable runway lights, increasing the risk for aircraft and ground crews.

Then there’s the safety factor. Working with high-voltage lighting systems, especially in an environment that operates around the clock, requires expertise. A single mistake could not only lead to equipment failure but also compromise the safety of flights and personnel. I knew attempting DIY fixes wasn’t an option when the stakes were this high.

Calling a licensed electrician for the job was one of the best decisions I made. When they arrived, they conducted a full inspection of the airfield lighting system, checking for faulty circuits, burnt-out transformers, and wiring irregularities.

Instead of just patching up the most obvious issue, they performed a comprehensive system check to ensure no underlying problems could cause failures in the future. They identified an overloaded circuit causing voltage fluctuations and promptly upgraded the wiring to handle the demand of modern airfield lighting systems.

The best part? They worked quickly and efficiently. What might have taken me days to troubleshoot was fixed in a matter of hours without disrupting airfield operations.

Once the job was complete, the difference was immediately noticeable. The runway and taxiway lights were stable, bright, and fully operational, providing clear visibility for pilots. No more flickering lights, no more power surges, and no more risk of unexpected failures.

More importantly, I had peace of mind knowing the system was safe, up to code, and built to last. I couldn’t believe I had even considered handling such a crucial task myself, the risks far outweighed the potential savings, and the expert service I received was worth every cent.
