Poor training, auto-dependency and low experience.
And of course we never hear about the close shaves that have occured due to the factors mentioned above. Surely ATSB must receive many reports from overseas or via manufacturer's incident/accident internal intelligence of what goes on in different countries.
Despite this it seems everything is hush-hush and Australian pilots never get to hear of these reports. Thank goodness for Pprune contributors who are far more effective in revealing vital flight safety information than government agencies like ATSB. Or that ineffective journal, Flight Safety Australia.
