I take it all on board, however.
The Civil Aviation Act at 1c requires of CASA that they provide clear and concise aviation Safety standards.
CASA has not achieved that, so surely that alone, with 100% of Industry concurring, would be a strong case that the Act itself has been breached.
Especially when compared with other ICAO organisations that managed to meet the requirements with clear and concise aviation standards.
Surely a Government initiated legislative change that removes 90% of a Businesses income (integrated syllabus) with no demonstrable Safety Case is basis for recompense.
