Yes I'm still unclear if the flight was conducted (or was required to be conducted) under Airwork or Charter.
This is of relevance regarding carriage of alternate fuel.
Does this judgement suppoet the contention that it was in fact charter - as implied in the slightly ambiguous CASA audit. This stated (with words to the effect) the AOC covered medevac charter operations.
If you classified the flights as "AWK" then you cannot have "passengers" on board.
Only crew can be carried on board an "AWK" flight.
