I think it's a useful maneuver in the same way that boxing the wake is
-- it tells the examiner you're really in charge of the aircraft and
pattern planning. We don't really do it for broken spoilers, that's a
once in a gazillion event. That's why the new PTS does not require an
actual landing with spoilers, only demonstration of glide path control
using spoilers alone.

The PTS should also require slips WITH spoilers not slips INSTEAD of
spoilers. That's the maneuver you will use, when too high, to get in
to a field, etc. Many pilots have no idea how steeply you can in fact
come down. We'll just have to train that on our own. I've been having
fun with students -- the challenge is, set up a landing so that you
will use full slip and full spoiler on final. If you have to back off,
you buy the beer (after flying)
