The new regulations are Part 133 (passenger carrying operations) and Part 138 (Aerial Work Operations). No such thing as charter anymore under the new rules. EMS are looking at being placed under the Part 133 rules by CASA. Not sure of the results but will have big impact on aircraft with PC1 etc.
I think Night VFR is a furphy and should be removed from the rule book. Gets very black out there in the GAFA............
