ALS Inspection

CANARD has developed a solution for quick and precise inspection of Approach Lighting Systems (or ALS) using drones. In the same way as other solutions from CANARD, it is based on a custom software, procedures and sensor-equipped RPAs (Remotely Piloted Aircraft, or drones), saving airport operators time and money in maintenance activities.

CANARD offers a fast, reliable and economic alternative to the conventional flight inspection of Approach Lighting Systems or ALS, allowing more flexibility and efficiency in maintenance activities. Our drones operate both day and night and align with the airports’ specific maintenance requirements.

Our solutions combines state-of-the-art hardware with our custom software and procedures to fully automatise the operation.

Safety is ensured with failsafes and other measurements implemented at 3 levels (Hardware, Software and procedures). We have cleared the regulatory hurdles to operate in the complex and restricted areas of the airside zones.

CANARD’s solution provides valuable information for the inspection and verification of the ALS:

• Check that all lights are operational
• Verification of the correct alignment of all lights
• Check the colour and relative brightness of lights

After the inspection, a report is generated in real time with the results and images of the ALS. A video with overlay data such as date, time, and approach angle of each frame is also generated for further analysis.

We help airports to:

• Decrease management time, and free-up maintenance staff capacity
• Significantly improve inspection accuracy and repeatability
• Comply with inspection timeframes by providing increased flexibility from operating day and night, and availability
