Having lived and worked in France, it is my opinion that 'Hofstede’s Power distance Index' is relevant to the discussion. I would bore you with details about France having the highest PDI of the western world, and indeed much higher than South Korea.
Much was made of this cultural phenomenon in the case of Korean Airlines sting of mishaps in the 80's/90's.
PDI is a good indicator of how likely a subordinate is to disagree with a superior, i.e. quality of CRM.
The Toronto crash stank of bad CRM, and this 447 crash is starting to look that way too.
Look at the number of flights heading in the same direction that day that didn't fly through the storm.
AF needs to seriously examine the effect of their national culture on their flying culture.
