blame the RAAF, it's their radar and it's not up to scratch. Darwin is not on its patma, the ESL radar was showing paints displaced by...well a fair distance...compared to the other feeds.
From the NT RAPAC meeting 27 June...
WGCDR Barbara Courtney, RAAF, responded to the issue advising the problem primarily exists with Airservices no longer taking the feed from Darwin RADAR. The reason for Airservices declining the feed is that they have experienced track drops and therefore consider it unreliable. Airservices are investigating why it is occurring, but until a solution is found they will not utilise the data. Prior to the problem arising Brisbane Centre would use the Darwin feed as an additional work tool. Now that they do not have the tool available their workload has increased, thus causing some delays to pilots.
Barbara further explained Darwin does not have an issue with the RADAR feed however they are investigating if the problem lies with the RAAF equipment. Until the issue can be resolved pilots may continue to experience some delays.
