Culture
I agree with most posters here about the culture problem. I'm surprised no one mentionned the incident involving an AF A320 in Muhamed V airport at Casablanca, when cleared for a visual approach for 35L, the plane landed on 35R, and this incident could have been serious. The briefing mentioned an ILS approach but the captain who was not the PF decided 4000ft AGL to perform a visual approach without any briefing while being PnF. Both did not detect (nor the ATC) the error until a RAM pilot, taxiing for 35L adknowledged the crew about the mistake. What is more alarming in this incident, and there the cultural part takes all its sense, is that the captain did not wanted to report the incident, did not protect the CVR or warn authorities. When incident was finally reported and the crew interviewed, captain stated that for him it was not worth mentionning it, if the RAM pilot did not told ATC, they would have parked without no one noticing, and the whole situation was not that critical.
Here you can spot AF captain thinking process.
