The sad part of his change is that CASA have disregarded the views of industry and made significant consultation with the RAPACs and others a waste of time. They can’t even write up the changes in a manner that can be understood. And it is my bet many pilots will continue to what they have done since 2003 and use 126.7 at low levels regardless if operating in the vicinity of airfields marked or unmarked on charts. Having a second frequency which promotes frequency separation is clearly less safe and the majority of pilots know that.
