Lightning Protection

Lightning strikes are a serious risk to airfields, capable of damaging runway and taxiway lighting, navigation aids, communication systems, hangars, and fuel storage facilities. Even a single strike can cause operational disruptions, equipment damage, and safety hazards.

At IAVNA, we provide specialist lightning protection services for airports and airfields, ensuring your critical infrastructure is safeguarded, compliant with aviation standards, and operational at all times.

Why Airfields Need Lightning Protection

Airfields are particularly vulnerable to lightning due to the combination of tall structures, open spaces, and critical electrical equipment. Key risks include:

• Runway and taxiway lighting systems: High-intensity lights and control cabinets (CCRs) are susceptible to surges and damage.

• Navigation and communication equipment: Radars, radios, and approach lighting systems can be disrupted.

• Personnel and aircraft safety: Strikes pose a risk to staff and aircraft on the ground.

• Operational downtime: Lightning events can force runway closures, delaying flights and impacting airport operations.

How Lightning Protection Works at Airfields

• A properly designed lightning protection system integrates multiple layers of defence:

• Air Terminals (Lightning Rods): Strategically placed on hangars, towers, and lighting masts to intercept lightning strikes.

• Down Conductors: Safely channel lightning current from elevated structures to the ground.

• Earthing Systems: Dissipate electrical energy safely, protecting runway lighting and sensitive equipment.

• Equipotential Bonding and Surge Protection: Prevent side-flashes and protect control systems, CCRs, and approach lighting.

• Regular Inspection and Testing: Ensures the system remains fully functional without affecting airport operations.
