CDU Crossing Detection Unit

Advanced Runway Incursion Prevention Sensor & Stop Bar Control System- Protecting Lives, Boosting Capacity, Reducing Costs

Runway incursions remain one of the most serious risks in airport surface movement – especially during low visibility procedures (LVP) and high-traffic operations.

The CDU Crossing Detection Unit from Airfield Lighting Systems delivers a modern, reliable, and cost-effective solution for runway incursion prevention. This advanced sensor system detects aircraft and vehicles crossing predefined safety lines at taxiways and runway entrances using embedded inductive loops, instantly triggering automatic stop-bar light activation/deactivation for immediate protection.

Real-time monitoring of stop-bar lamp status, combined with runway incursion alarms compatible with A-SMGCS highest protection levels, enhances safety during low visibility procedures (LVP) and high-traffic operations. Featuring ultra-low power consumption (15W), IP67 protection, redundant architecture, interference-immune fiber optic communication, and minimal maintenance, the CDU boosts airport capacity, reduces costs, and safeguards lives at critical holding points—fully compliant with the latest international standards.
