Busan now has a giant checkered board on that terrain north of the airport as well as a series of lead-in lights.
This seems to be an odd safety response – the hazard still exists (short of bulldozing a mountain).
Wouldn’t the use of a PANSOPS procedure and higher circling altitude be more effective?
This is a “How can we do this”’ solution opposed to “Should we be doing this” safety response.
