DeTect\'s HARRIER Aircraft Detection Lighting System (ADLS) provides reliable, continuous 360 degree radar surveillance of the airspace around wind farms, communications towers, power lines and installations that require aircraft obstruction lighting. Harrier automatically issues signals to activate obstruction lighting when aircraft are detected at a defined outer perimeter. The system is the most capable technology available and meets or exceeds all regulatory requirements including the recently issued US Federal Aviation Administration (FAA) Advisory Circular and Canadian NAVCAN requirements and well as various EU standards. The FAA Performance Assessment Report states that HARRIER ADLS system met “the performance requirements identified in Chapter 14 of AC 70/7460-1L” and is published on the FAA Website. The HARRIER ADLS visual warning system additionally is compatible with all wind energy turbines, control and communication networks, and obstruction lighting systems. The same system can be used for bird and bat surveys, mortality risk assessment, operational monitoring and real-time risk mitigation for windfarm sites.
