Varsling av luftfartshindre - Australia - Curt Lewis

 Et varslingssystem basert på transponder ble utviklet i Norge for emtrent 20 år siden. Et veldig enkelt system som tapte i kampen mot det radarbaserte  OCAS som vi vet ikke var særlig politelig. OWS 360 som det konkurrerende system ble kalt, var ypperlig egnet for varsling av master- og spenn. Det tapte fordi det kun tok fly med transponder, noe alle fly som driver kommersiell virksomhet har installert. (Red.)  

Australia’s Civil Aviation Safety Authority accepts DeTect’s radar-activated obstruction lighting system

Harrier Aircraft Detection Lighting SystemDeTect has announced that Australia’s Civil Aviation Safety Authority has accepted its Harrier Aircraft Detection Lighting System (ADLS) for use on Australian wind farms.

DeTect’s ADLS delivers continuous 360 degree radar surveillance of the airspace around sites automatically activating obstruction lighting only when aircraft are detected at a defined outer perimeter. The Harrier ADLS is compatible with all turbines, communication networks and lighting systems. DeTect developed its ADLS in 2008 in response to the Dark Sky Initiative to reduce light pollution for projects with aviation obstruction lighting such as wind farms, high voltage transmission lines and communication towers.
