Iīve done it a few times in rhs A340 and lhs MD11 in real life in the dark.
The approach is as straight forward as a visual can be!
Thereīs nothing in the bay you can hit, no noise restricted areas or weird profiles.
All you have to do is hold the heading and altitude, take the time, make the turn, donīt let the nose drop etc., etc. - and have a guy/gal next to you watching the altitude and backing you up...
But itīs still possible to mess up any approach, which does after all happen to all of us.
Just gotta know when and how to abort.
If you donīt do the go-around because youīre gonna lose your face - THEN do you have a problem.
Just my 2 cents - have no idea what the KAL-folks did.
