Thankyou for posting the info
Airspace
.
Free in G
In Canada and the UK, an aircraft can fly IFR in Class G without a directed traffic service and not pay an enroute charge. Australia should harmonise with this as per the NAS policy.
.
Terminal airspace size
Larger Class D and Class C airspace around Australian towers means that greater diversions are required by aircraft avoiding the airspace.
.
Restrictive Military Airspace
In Australia aircraft are required to fly extra distances to avoid military airspace. In the USA and other countries they have Military Operation Areas, which aircraft can track through if military flying training or similar activities are taking place.
.
UNICOMs in lieu of Certified Air/Ground Operators
Australian Certified Air/Ground Operators need to have held an air traffic control or flight service licence. In the USA, any skilled person can operate the UNICOM, with far lower costs.
.
Charting
Simple Class D airspace in the USA means that a Visual Terminal Chart is not required for Class D. Many hundreds of thousands of dollars could be saved by showing the simplified NAS Class D airspace on the Visual Navigation Chart rather than printing extra Class D VTCs.
… I don’t disagree with the first one .. that aside …. OK, so in the airspace context you forwarded this, which is clearly your view/s rather than those put forward in this thread … so what was the point of it?
.
Also, a question arising … did you couch this input as your opinion/s or the industry’s opinion/s??
