>Emirates is telling pilots not to set the altitude to zero on approach, for fear of the next crew not changing that. that sounds like a typical result of Six Sigma/5 Whys/<whatever spawn of the PM/MBA methodology hell they are practicing there>. If one thinks a bit (note: not a part of any such methodology) there is a reason why previous - ie. landing - crew sets the target altitude to that of that target airport... I wonder whether there is a narrow specialization - ie. the managers doing safety analysis of take offs are different from that of landings :)
