Fujii, if what you are saying is AsA policy/mindset, I am worried. Are you seriously suggesting that a mitigator for a simultaneous G/A is the different heights that the aircraft will cross at? Just as concerning is your suggestion that "if required the 34 aircraft could be turned towards the 27 threshold". In the short time available, I seriously doubt whether the controller could accurately predict which way/how much to turn. Do they have dogfight training?
What is the visual standard when two aircraft are basically on a collision course within a couple of miles of each other with no organised vertical separation? Turn one so it missed the other by 500m?
I'm all for LAHSO, but not like happened there.
