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 1 standards, 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.

Powered by an internal lithium battery with up to 8 hours of continuous use and a long LED lifespan of 60,000 hours, this lightweight (2.8 kg) and portable device requires no optical realignment after maintenance, minimizing downtime and making it an essential, low-maintenance addition to any air traffic control or emergency response toolkit.
