Let’s assume that the ATSB’s analysis is correct and your impressions are correct.
What is it in CASA’s response - the imposition of conditions on flight crew licences - that causally mitigates the risk of community service flight pilots being more likely to make decisions that result in fatal accidents? Which of those conditions would have prevented fatalities?
And why wouldn’t we want to see the statistics of male v female fatal accident rate? Surely there should be a regulatory response to the disparity. After all, there must be a causal connection, not mere correlation.
