Va and negative g's & fun non-acrobatic maneuvers

Do they no longer teach to "unload" the aircraft as an initial part of
unusual attitude recovery?

It can be done from cruise speed. Pull up into a shallow climb,
then start pushing forward, increasing pressure until the pencil comes
off the panel. It'll feel like negative G's but isn't. The only stress
on the airplane occurs when you pull out of the shallow dive created
by the maneuver.

It will need to be a brief amount of negative g or the pencil will not come
off the power. It will hover where it was with = 0g.

Did they ever?

I have this mental image of me climbing into the back seat to toss luggage out
the door before initiating recovery from an encounter with wake turbulence.

Some people think they hear a call to the priesthood when what they really
hear is a tiny voice whispering "It's indoor work with no heavy lifting".

My kids love it when I do this. Never floated a pencil or anything, but I
take them on "roller coaster" rides every now and then. They can't stop
giggling.

and it doesn't require abrupt, or anywhere near full, control inputs.

The ONLY sensible post in this whole thread! I "float" stuff with
all of my new students, makes them feel like an astronaut. And
that's in a Cessna-172. Who cares if the engine sputters? All of
you sissies go back to MSFS. Its not an aerobatic maneuver and
doesn't require areobatic training!

But the last line of your post says it all. For an ATP CFI who has
done it hundreds of times before, sure. For a fairly new pilot
who has never done it with a CFI beside him... not so good.
If he's worrying about negative AOA stalls then he's clearly
thinking about more than a 0.1G push-over.

What do you do about getting the dust out of everywhere
afterwards? Or do you do it often enough in the same plane
that the dust doesn't accumulate (as happens with acro planes)?

We keep our airplanes clean.

I'm wondering how this maneuver risks breaking or stalling the
airplane, as some earlier posters indicated. Done this numerous times,
and the carbureted engine didn't cough, either. It's only for a second
or two. G forces on pullout are minimal. People who level off too fast
from a climb can get the same effect. Rough air on a warm day, or a
windy day in the mountains, can be much worse. Should we avoid flying
then, too?

FAR 91.303, Aerobatic Flight, states in pertinent part:

"For the purposes of this section, aerobatic flight means an
intentional maneuver involving an abrupt change in an aircraft's
attitude, an abnormal attitude, or an abnormal acceleration, not
neccessary for normal flight."

In the context of the Cessna 172, it could be argued (especially by an
ornery FAA-type) that the "float the pencil" maneuver results in both
"an abnormal attitude" and an "abnormal acceleration," and is "not
necessary for normal flight."

What exactly constitutes an "aerobatic maneuver" is left open for
interpretation, and in the end depends on who's looking...

And while the reply below is good, it is debatable whether or not it
is the ONLY sensible one thus far. Given that the original poster has
never done this before, isn't it prudent to suggest he get some dual
in the particular maneuver before attempting it by himself, or worse,
attempting it for the first time with the plane loaded with someone
else's kids???
