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.

Because the navaid is not on the extended runway centerline.=20

Furthermore, those alignments usually are not to the airport reference =
point,
but instead cross that centerline somewhere near the approach end of the =
runway,
just far enough out to turn and land if the runway environment comes =
into view.
