creampuff has highlighted the essence of the insanity that CAsA has become.
you cannot predict the future.
you can have a good guess at it but the inherent randomness of life is always a confounding factor.
What the semantic weakness in the act has done is cause the "we know safety" nutters in CAsA to try to force the future.
"safety" and "luck" are exactly analogous. neither is an actual entity in itself. they are descriptions applied to the successful outcome of some activity.
if the act was changed so that the Western Australian Lotteries commission was charged with assuring that every person who bought a lotto ticket won the lotto you would immediately see the stupidity.
Mix a bit of the fear of death in and CAsA is charged with an impossible undertaking. Nobody seems to see the idiocy built into the Act. You cannot predict the future.
The people with colour vision differences are not deficient.
Look at them. 25 years of safe aviation and they are all healthy individuals.
CAsA on the other hand are demonstrably insane.
