ALDIS Aviation Signal Gun

The Aviation Signal Light Gun (ALDIS) from ALS is a modern, high-performance LED-based signaling device engineered for air traffic control and ground operations at airports worldwide. Fully compliant with ICAO Annex 14 Volume 1standards, this reliable tool enables clear visual communication with aircraft, especially in scenarios where radio contact is unavailable or unreliable.

Featuring powerful LEDs that directly emit red, white, and green signals—no filters required—the ALDIS delivers exceptional visibility exceeding 4.1 miles (6.6 km) even in bright daylight conditions, ensuring pilots receive unmistakable instructions for landing, takeoff, or holding patterns.

Designed for demanding airport environments, the ALDIS offers user-friendly operation with intuitive switches for quick color selection and a 2-position toggle for continuous illumination or Morse code signaling. Its integrated sighting scope enhances aiming precision, while the durable construction provides an IP34 protection rating and reliable performance across extreme temperatures from -30°C to +55°C.

 

Protect Your Airfield from Lightning Strikes

Lightning can pose serious risks to airfield infrastructure – from runway and taxiway lighting, to navigation aids, control towers, and even aircraft on the ground. A single strike can cause equipment damage, operational disruption, and safety hazards.

At IAVNA, we provide specialist lightning protection solutions for airports and airfields:

  • Tailored risk assessments and bespoke system design
  • Provision of air terminals, down conductors, and earthing systems
  • Surge protection for CCRs, lighting, and navigational aids
  • Ongoing inspection, testing, and certification to ensure compliance with BS EN62305 and aviation standards.

Protecting your infrastructure isn’t just about safety – it’s about business continuity, regulatory compliance, and long-term cost savings.
Keep your airfield safe and fully operational, whatever the weather.

 

 

 

High-Profile Runway Lighting Installation Completed on Assomption Island, Seychelles

ALS (UK) Ltd is proud to announce the successful completion of a major runway lighting installation at Assomption Island Airport, a strategically significant and highly remote location in the Outer Islands of the Seychelles.

Assomption Island lies approximately 1,135 km south-west of Victoria, the Seychellois capital, and north of Madagascar. The island presents unique logistical and environmental challenges, requiring robust engineering solutions and careful project execution. The newly completed airfield lighting system was delivered for a high-profile private client, with the highest standards of performance, reliability, and discretion.

The scope of works included the supply and installation of a complete LED airfield lighting system, featuring:

  • LED runway edge lighting
  • Elevated runway lights
  • Inset runway lights
  • Threshold lighting
  • Taxiway lighting
  • Associated primary and secondary cabling

All equipment was selected to provide long service life, reduced maintenance requirements, and optimal visibility in tropical operating conditions.

The project also required detailed planning and coordination due to Assomption Island’s remote location and its strategic importance. Since 2018, the island has hosted a joint Seychelles–India military facility, making compliance, resilience, and operational integrity critical factors in the design and delivery of the system.

This installation further demonstrates ALS (UK) Ltd’s capability to deliver complex, high-value airfield lighting projects in challenging environments worldwide, supporting private, commercial, and strategic aviation operations.
