With Australia's airspace about to undergo radical change as of Nov. 27, controversy over the new rules is intensifying. Aviation industry experts have raised concerns about the change, which will make the system more like the one in the U.S. Air traffic controllers say the new system will pose a significant safety risk. Pilots complain they have not yet been informed of the new procedures they will need to follow. Other critics add that Australia's radar coverage is inadequate. Transport Minister John Anderson said this week a comprehensive training and education package would enable pilots to move safely to the new arrangements. Anderson added that all pilots will receive an initial subscription to new improved charts for their area of operations.
