Perhaps I'm misinterpreting what you've written, but how is this different
than a 'real' precision approach?


When you reach the MAP after D&D, you're stable in three axes. How would you
rather be when looking for the runway?


When you reach the MAP after following a glide slope, you should also
be stable in three axes (heading, pitch, and bank should all be
constant). Even better, if you see the runway, you can continue to
hold that attitude down to the surface.

If anything, the slight nose-down pitch attitude should make it easier
to see the runway, compared to having to search for it over the nose
in level flight after a dive-and-drive.



A factor I didn't see mentioned:

A coupled autopilot can fly a WAAS approach. It cannot do dive and drive.
