And anyway, many of these problem would not have happened if like the rest of the world you have two pairs of eyes per sector.
It is unbelievable that in australia we use an atc system that only have a stca function (from memory 60 seconds before impact) that only works in radar coverage.
Most of you don't realize that out side radar, the only thing stopping a mistake is one person sitting watching. There is no conflict alarm. It is all done by one person watching the screen finding the conflicts by himself. The system does not point out any conflicts.
