Maybe if people actually listened
... or if it even mattered that pilots might taxi across/along an inactive runway. An inactive runway is a taxiway in anyone's book except the new DAS
... or if the hold points for inactive runways had lights at night, so we could see them
... or if any controllers, pilots or operators had actually been listened to before this stuff was implemented
If runway incursion numbers went up, and all of those were on runways which were inactive at the time, there is no safety case.
Two runway closures in two days at Bankstown - Nothing to do with inbound reporting points, or the number of aircraft in the circuit, or tower being staffed during all daylight hours. So nothing that's come from CASA in the last few weeks would have changed those accidents.
In spite of that, it's clear that CASA are working on a complete solution - If they make it sufficiently difficult to get airborne there will be no flying, and therefore no flying accidents.
