Many thanks to all for your insights on thisinquiry. I didn't know that the aircrewshave airfields already identified for possible diversion readily available onthe flight deck. And to the point of theQantas diversion to Ontario, Ca in 2015 due to fog, I'm just curious why such amodern aircraft would need to divert for fog when I believe the plane isequipped with an autoland function? Doesanyone have experience with diverting due to fog electing not to autoland?
