Not sure of your point here
I was talking about "tight" not "unsafe" procedures.
On introduction of the 4th runway in FRA the procedures were " tight" they have been revised since, but you land less a/c per hour.
LAHSO :these are very tight procures. so tight that some (e.g BALPA and BA,just to name 2 ) refuse them on principle. Does not mean they are unsafe.
I made a LAHSO in BOS on a Dash 8 in the jumseat some years ago, while a DC10 was landing on a interecting runway . Great .I asked what happens if both decide to go around at same time in poor vis ? I agree the likelyhood of this happening is remote, but I could hear Murphy laughing out loud in the background.
There was a time where Safety was first, now it is number of movements per hour...Unsafe ? probably not, Tight?, yes.
