How many operators cried poor when CASA mandated GPWS/EGPWS, the outcry in the newspapers etc etc, or the Cessna SID ( although I feel that was very very very very poorly executed).
In the case of GPWS, I believe there is sufficient statistics to prove it was a good move for Safety, a big thumbs down for the popularity vote.
If operators can't afford to be in the Aviation Industry, how can they afford to be in the Aviation Industry ?, if you catch my drift.
