AsA have now claimed that they use the radar ( OK - multilateration) operated from the Melbourne centre for separation when the tower is closed but use non radar procedural when the tower is open and airline passengers are flying.
This seems the opposite to commonsense.
Can anyone explain?
Block. Procedural control surely can't be as safe as a servailence based service. What happens if a pilot makes a simple error and descends too early coming in from Flinders Island to Launy? It happened at Cairns and was only saved by the radar operator.
Or are our professional pilots perfect?
