Busan does require specific sim training but the term should be used loosly.
The sim does little more than demonstrate how silly the whole idea is and how unstable you will be in final approach.
Why can you fail a checkride being unstable at 1000' on a long dry runway straight in approach in good viz but still being unstable at 200' in the sim in Busan is fine?
Ahhh, KA. Such difficult crap gets dished out in the sim and yet line flying is a big chunk of cheese.
