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.

Further, this is still - unless I'm misinterpreting something here - the
same situation as that of a precision approach.

The cited article on AVWeb makes a big deal of the runway not being right on
the nose for a nonprecision approach. However, the runway is often not
right on the nose for a precision approach. It depends upon the wind.

A review of the approach along with an awareness of the heading should be a
pretty good indication of the direction in which one's head should turn.

A factor I didn't see mentioned:

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

A coupled approach does let you keep your eyes outside, especially during
the transition phase, but how many are equipped with AP's that can do
coupled approaches?

Remember: CONTEXT.

I've got an WAAS-enabled GPS, GPSS, and an autopilot that will fly
coupled approaches.

So do I. We're a distinct minority. So what?

Anybody with a IFR capable GPS is a minority. Anybody with
a really capable IFR panel that's legal to use IFR is a minority.

What freaking CONTEXT are you talking about.

Most of the ones with WAAS boxes I would guess.
