The OCAS Wind Farm: Enabling our nation´s wind farms and communities by making our skies clear and safe.
Intelligent On-Demand Lighting System for Wind Farms Wind Turbine Collision Avoidance System An FAA-approved day and night wind turbine collision warning system. Turbine obstruction lights remain OFF at all times and are only activated when aircraft are operating in the vicinity of wind farm. Radar mounted on turbine tower detects aircraft and turns on all wind farm obstruction lights for immediate primary visual warning. Secondary audio warning via VHF radio to all aircraft and pilots in proximity. Always monitored and fully redundant system.
Overall Benefits for Wind Industry and Local Communities: Turbine obstruction lights are always OFF – unless an aircraft is detected Lower overall visual impact of your wind farm. Increase public acceptance in nearby communities due to decreased visual impact – especially at night. Reduce light pollution. Lower avian mortality rates since migratory birds less likely to be attracted to wind farm lights. Satisfy FAA guidelines as per FAA AC 70/7460-1K and Transport Canada CAR 621.19.
Financial Benefits for Wind Developers Improve ROI of wind farm development:
• • • •
Faster Permitting: By increasing public acceptance, potentially facilitates a faster permitting process that saves cost associated with delayed and longer project timelines. Additional Opportunities: Potentially permitting at sites previously not possible. Increase Energy Output: Potential for taller, higher power-yielding turbine hub heights where local regulations may restrict heights due to nearby flight safety risks or light intensity requirements. Lower Maintenance costs: Fewer light “on” hours increase light life and requires fewer visits to site.

0 CAS' Audio Visual Warning System (AVWS) What OCAS Does: At the heart of the OCAS solution is a low-power, continuous wave radar that scans for aircraft in the proximity of the wind farm. The radar not only identifies, but also tracks the aircraft’s heading, speed, and altitude and determines if the aircraft is following a course which may bring it to dangerous proximity of the wind turbines. Thirty (30) seconds prior to any calculated impact with a turbine, the OCAS system immediately initiates the primary visual warning by turning on all wind farm strobe lights per FAA and Transport Canada guidelines. If the pilot has not sufficiently altered course twenty (20) seconds prior to impact, the OCAS solution broadcasts a secondary audio alarm to the pilot via VHF radio in the general aviation band. When the aircraft no longer poses a threat, the wind farm lights are turned off.
