Stable approaches for the heavy metal???? Stable approaches work for all
aircraft on non-precision approaches.


Wanna re-read my original post.

Indeed they do, but the intent was the turbine traffic, not 172's.

Maybe someone explained them to you
poorly or incorrectly. Stable means a constant descent rate that puts you
at MDA shortly before the MAP.


I know what they mean.

Dive and drive is frowned on by the FAA
because of the multiple accidents nor near mishaps or altitude busts that
occur.


Do you have a cite for that?

One of the cool things about WAAS is the ability to fly a synthetic
glideslope on a non-precision approach. I'd much rather follow a
needle smoothly down to MDA than dive-and-drive through a couple of
stepdowns, even if the MDA is still the same 500 AGL or whatever.


Problem with a smooth descent is that when you arrive at the sectors

MDA,
you have immediately start down again rather than taking a few moments

to
sift things out. Stable approaches were build for the heavy

metal/turbine
crowd.

Pelican's Perch #24:
Sloppy, Sorry VNAV

Flying a non-precision approach has traditionally been a "Dive and

Drive"
affair in which the pilot descends rapidly to the MDA or step-down
altitude
and then levels off. Recently, however, pilots of aircraft equipped with
glass cockpit FMS systems or VNAV-capable GPS receivers have been
encouraged
to fly such approaches using a constant descent path. There's even a
buzzword for this: CANPA (constant-angle non-precision approach), and
these
calculated pseudo-glideslopes are now starting to show up on Jeppesen
approach plates. AVweb's John Deakin thinks this is a bad idea, one that
will result in a lot more missed approaches and perhaps even some
accidents.
Deakin explains why, and makes a compelling case for flying

non-precision
approaches the traditional, old-fashioned way that God and Cap'n Jepp
intended.
