Vilas, you're obviously knowledgeable on the matter at hand. Your last post mentions (rightfully) that EK in DXB may have been avoided if briefed. That's true for the vast majority of accidents. At what point do you stop briefing though?
Someone's mind is likely to start wandering about a minute into the approach and landing dissertation that some people give. I find it more effective to spend most of the time focusing on what's likely to go wrong, instead of going down the never ending list of what could go wrong.
