Safety Recommendation
The ATSB recommends that the Civil Aviation Safety Authority, in
consultation with Airservices Australia and the NAS Implementation
Group, review NAS procedures and communications requirements for
operations in Class E airspace, with particular emphasis on air
transport operations during climb and descent in non-radar
airspace, with a view to enhancing situational awareness of pilots
operating in that airspace. The review should include examination
of, and where necessary revision and updating of, education,
training and chart frequency material.
