The title just about says it - I've always wondered WHY many
non-precision approaches (not talking about LOC only here, but VOR,
VOR/DME, NDB etc) are not lined up with the runway heading. Sometimes it
looks as though the approach desginers have gone out of their way to
make sure the non-precision approach is just a few degrees off - as if
to say - "look stupid - this is not a precision approach . . ." But if
this were so, then we would have to wonder why SOME of these approaches
ARE lined up and straight-in. I'm surev there's a simple explanation
that will be pointed out here.

This has little to do with non-precision / precision classification.

If you can get hold of them, get some ILS approach plated for
Norway. There are ILS:es with approach path 60 degrees off
runway direction.

The approach path has to fulfill separation requirements for
both other flight procedures with protection zones and for
obstacle celearance.
