Captain Midnight: it would be worth having a read of the new CASR Part 175 and updating yourself on what the requirements are now for Aeronautical Data Originators in Subpart 175.D. It's not like it used to be. The privacy of individual aerodrome owners, and their right to
not be published (for any number of reasons), also needs to be respected.
For those interested in this thread's headline topic of CASA's constraint on the MULTICOM: there's more info now at
RAPACs .
