Cottbus-Neuhausen Airport in eastern Germany has recently upgraded its Precision Approach Path Indicator (PAPI) system to meet the latest EASA technical requirements. The airport selected S4GA’s double-projector LED PAPI, a solution fully compliant with EASA standards and designed for safe, modern, and energy-efficient airfield operations.
The project was delivered in collaboration with Innovence Airport Systems GmbH, S4GA’s local partner in Germany, while system integration with the Airfield Lighting Control and Monitoring System (ALCMS) was completed by AP-Tech.
The upgrade was initiated to comply with the EASA multi-lamp requirement, enhancing safety and operational reliability for pilots during approach. Cottbus Airport required a modern PAPI system that would not only meet all new regulations but also provide long-term efficiency and straightforward maintenance.
The project team faced several technical challenges during implementation:
S4GA supplied and commissioned its double-projector LED PAPI system, featuring dual redundancy, precise photometric calibration, and energy-efficient LED technology.
Integration into the airport’s ALCMS, enabled seamless real-time monitoring and control directly from the control tower.
The system also includes self-monitoring capability with live feedback on tilt and operational status, allowing maintenance teams to quickly detect and address any irregularities — further increasing reliability and uptime.
The new PAPI system provides Cottbus Airport with:
Cottbus Airport is now equipped with a modern, efficient, and reliable S4GA LED PAPI System that enhances both safety and operational performance — an upgrade any airport can consider to ensure full compliance, low maintenance, and top-tier reliability.
