0.4 4% 2% 7% that number doesn't really matter, I'm just pointing out that there are 5 flights every day where the Pilots feel the need to report a serious safety concern, that's all. I'm not looking for a fight.
I am well aware that for every report that is filed, there are many that should have been filed but were not for a variety of reasons. It seems that CX feel it is "OK" for their aircraft to be flying along at 950km/h likley in the middle of the night in poor weather & over significant terrain or possibly conducting a challenging instrument approach, with Pilots up the front who are so tired that they feel they need to inform the regulators. This is a preface to an accident, plain & simple.
