Hong Kong Runway 13 . I guess you are thinking of the the turn following the IGS approach. I am speaking of the NDB CC (no IGS/VOR then) which was a break cloud to visual. The difference of track from the NDB to runway heading was, I believe about 100 degrees, so, if visual, many people took it wide around stonecutters giving a better radius of turn but a larger turn angle. There weren't any published figures then as it was just "visual"
