• Airport Runway Foreign Object (FOD) Monitoring

  • Airport Runway Foreign Object Monitoring System

    FOD (Foreign Object Debris) refers to any foreign matter, debris, or object present in airport operation areas that could potentially damage aircraft or systems.

    As airport traffic increases rapidly, there is an urgent need for more efficient and accurate FOD detection solutions.

    Current Situation:
    Most airports in China still rely on multiple daily manual walkthrough inspections to detect FOD.

  • Main Characteristics

    Types of FOD

    • Metal parts
    • Rubber fragments
    • Plastic items
    • Concrete/asphalt pieces
    • Paper products
    • Animals and plants

    Hazards

    • FOD can be found on runways, taxiways, and aprons
    • FOD on runways poses the most serious threat to aircraft safety

    Challenges of Traditional Methods

    • Visual identification is inefficient
    • Manual marking and classification only
    • Real-time monitoring is impossible
    • Runway must be shut down during inspection

  • Airport Runway Foreign Object Monitoring System – Market Demand

    With over 250 airports in China and increasing runway traffic, there's strong demand for efficient FOD (Foreign Object Debris) detection. Regulatory policies from the Civil Aviation Authority and safety needs are driving adoption. Fixed systems are needed for major airports, while mobile solutions serve smaller and overseas airports.

  • Main Characteristics

    Market Capacity

    • Civil Aviation:

    - 259 airports

    - 54 airports rated 4E and above (with 289 runways)

    - Fixed detection systems needed for nearly 90 major runways

    - Mobile systems needed for smaller airports

    • Military airports: several
    • Overseas demand: Southeast Asia, Middle East, etc.

    Demand Drivers

    • 2016.07: CAAC (Civil Aviation Administration of China) released industry standard “Airport Pavement FOD Detection Equipment”
    • 2023.11: CAAC issued “Regulations on Safety Management of Transport Airports” – encouraging FOD deployment
    • Systems already deployed at:

    - Beijing Capital / Daxing

    - Chengdu Tianfu

    - Others for commercial benchmarking

    Product Types

  • Systems Overview & Installations

  • Ground-based InSAR Radar (Slope Radar)

    Mandated by national mining safety regulations and driven by frequent geological disasters, the demand for slope radar is rapidly growing. It offers non-contact, wide-area deformation monitoring—essential for open-pit mines and emergency response scenarios.

    Purpose:

    • Monitors surface deformation of slopes continuously
    • Detects deformation trends
    • Issues landslide early warnings

  • Main Characteristics

    Demand Drivers

    • Mining Industry:
    • National standard mandates slope radar systems for open-pit mines
    • Aug 30, 2023: National Mine Safety Administration issued Notice No. 119 mandating implementation
    • Geological Disasters:
    • Frequent major landslides, growing need for emergency monitoring

    Technology Drivers

    Technology Drivers:

    • Traditional methods (crack meters, total stations, GNSS, RTK, fiber optics):
      • Contact-based, point measurement – limited effectiveness
    • Current industry need:
      • Non-contact, surface-wide measurement

    Emergency Cases Cited

    • Alxa League Xinjing Coal Mine landslide
    • Ya’an Earthquake Barrier Lake emergency response
    • Maerkang landslide emergency response

  • Ground-based InSAR Radar – World-First Innovations

    Leike developed the world’s first electronically scanned slope radar using MIMO phased array technology. It enables real-time, non-contact surface monitoring with high precision, offering a safer and more efficient alternative to traditional point-based methods.
