JD-EE,
Who carries with it implicit blame for the person. Why at least "spreads the blame" to perhaps faulty stimuli, faulty training, he just had a bad day, and other possibilities.
With due respect, but I fail to see how having a bad day can be an excuse. If a pilot has a so bad day that it can impairs his/her judgement, he/she has the option of staying home, sparing the lives of a lot of people. In fact itīs not an "option", is a moral obligation.
And in fact it seems that the less experienced pilot was commanding the airplane. This raises some interesting questions beyond his own hipotetycal culpability: for example, is it considered to be good practice for a captain to let the less experienced pilot drive the thing during the crossing of the ITCZ? This is a fair question, you see, even if in the end BEA investigation proofs that the pilot received erroneous information from the system.
