A single bolt left on a runway costs the aviation industry $4 billion annually. One inch of undetected ice causes a 10-minute delay that cascades through global flight networks. Your manual inspections catch 23% of debris—automated IoT sensors catch 100%. The difference between proactive monitoring and reactive crisis management is measured in lives, dollars, and operational chaos. Stop gambling with runway safety—deploy intelligent sensors that monitor pavement temperature, detect moisture before ice forms, and identify foreign objects smaller than a golf ball in any weather condition.

Deploy real-time pavement temperature sensors, automated moisture detection, and AI-powered foreign object debris systems that keep your runways safe 24/7—in any weather condition.
The Hidden Cost of Unmonitored Runways
Every minute of runway downtime, every undetected hazard, every delayed flight compounds into billions in losses annually.
Engine damage, punctured tires, aircraft out of service time—Boeing estimates direct repair costs alone at $4B yearly
Including flight delays, cancellations, lost revenue, passenger compensation—FAA estimates true costs up to $22.7B
Each minute of delay costs airlines $62.55 in crew salaries, fuel, and operational costs—compounding across networks
On average, 12.8 FOD incidents occur per 10,000 aircraft movements—at $26 direct cost per flight
⚫ The Air France Concorde Disaster
On July 25, 2000, a single piece of titanium debris on a runway at a major international airport caused the catastrophic crash of Air France Flight 4590, killing 113 people. The debris—part of a thrust reverser from a previous aircraft—punctured a tire, rupturing a fuel tank and igniting a fire. This tragedy transformed global FOD awareness and prevention standards.

Advanced FOD Detection Technology
Millimeter-wave radar combined with AI delivers 100% runway inspection for every flight—not just 1% with manual checks.
How It Works
Continuous Scanning
76-96 GHz millimeter-wave radar continuously scans the full runway width, detecting objects with radar cross-section as low as -20 dBsm
AI Classification
Advanced algorithms distinguish FOD from background clutter, pavement features, and false alarms—eliminating 99% of false positives
Visual Verification
High-definition day/night cameras automatically cue to detection location, providing visual confirmation before dispatching personnel
Guided Removal
Laser beam guidance directs ground crew directly to exact FOD location—minimizing runway closure time and maximizing safety
Detectable Objects

Frequently Asked Questions
How do embedded pavement sensors withstand aircraft loads?
Modern embedded sensors use flush-mount designs that sit level with the pavement surface. The sensor housing is engineered to distribute loads across the surrounding pavement, and vehicles (including aircraft) can drive directly over them without causing damage. Some sensors use two-part housings that allow maintenance access without disturbing the pavement.
Can FOD radar systems operate in heavy rain, fog, or snow?
Yes, millimeter-wave radar is specifically chosen for FOD detection because it operates effectively in zero-visibility conditions. Unlike camera-based systems, radar penetrates fog, rain, and snow. Advanced systems like Tarsier and FODetect guarantee operation in all weather conditions, including high temperatures, sandstorms, and frequent fog.
What's the minimum detectable object size for FOD radar?
FAA-certified systems can detect objects equivalent to a metal cylinder 38mm in diameter and 31mm high (roughly the size of a large bolt) at distances up to 1,000 meters. The Tarsier system achieves 100% detection at 3,168 feet, exceeding human visual inspection capabilities significantly.
How do ice detection sensors work with different de-icing chemicals?
Active sensors measure the actual freezing point of the surface liquid—regardless of which de-icing chemical is used (sodium chloride, potassium acetate, formates, etc.). This is critical because airports use different chemicals than road salt, with freezing points as low as -60°C depending on concentration.
Do runway sensors require runway closure for installation?
Embedded sensors typically require brief runway closure during installation—often scheduled during overnight hours or maintenance windows. However, once installed, the sensors operate continuously without requiring additional closures. Some mobile and non-invasive sensors can be deployed without any runway closure.
How do these systems integrate with existing airport operations centers?
Modern runway monitoring systems provide standard data interfaces (Ethernet, serial, API) that integrate with existing Airport Operations Centers, AWOS/ASOS systems, and maintenance management platforms. Data can be displayed on existing monitoring screens, and alerts can be routed through established notification systems. OxMaint provides pre-built integrations for seamless connectivity.
