Mild Aerobatics

I allowed one of my "Young Eagles" to do some of what you call "Ups &
Downs" once. Her two friends in the back seat became pretty queasy in
short order and were not pleased with her. That sort of thing got removed
from the menu for my flights.

Yeah, up/downs can get pretty ugly, if done too often.

My kids usually beg for one, ask for one more, and then are happy not to do
a third, especially when it's hot.

I could be wrong, but doesn't it matter a LOT as to how quickly the maneuver
is stopped and started? Like, an up down done over 9 seconds is almost no
strain, and one done in 3 seconds is *considerably* more strain on the
plane?

Yeah, I'm wondering that, too.

Everyone is saying I didn't put too much negative G on the airframe -- which
is nice to hear -- but it was a pretty abrupt maneuver. I know when I do
"up/downs" with the kids, if I do it long and slow, it's a lot easier on
everyone than if I yank and push.

Hopefully pushing hard didn't stress things too much...

Really unlikely. When you're on the ground, the wings aren't holding the
plane up. The landing gear is. You, probably, didn't even hit -.1G. -1 is
everything plastered against the roof. You probably didn't put much more
stress on it than a take-off at gross.

That being said, DHs advice is as sound as any I've seen on the subject.
Unless you're really competent with acro, even something as innocent as a
chandelle or lazy 8, spiral or spin can quickly get out of hand and stress
the airframe.

Gs are Gs. I know what you're saying -- an abrupt application *could* yield
some pretty high instantaneous G force, but keep it simple. Did anything
come off the floor and slam right back down during your avoidance maneuver?
Did you feel a quick but unmistakable tug on your belt?

If the view out the front didn't look like the picture I just posted on
alt.binaries.pictures.avation you are probably allright (View out the
windscreen).

If you went really negative you would have been banging your noggin on the
overhead.

Hold a pencil up, do a Humpty-Bump, then let go and watch the pencil
float in the air.

A friend has a 182 and we have rolled that many times. Another buddy
has a Baron and we have rolled that many times. Yet another friend has
a Super Cub and I have gotten fairly proficient at rolling and looping
that. In my plane I frequently take it up and go power at idle, full
back stick and hold a 45 degree bank. I have VG's so the plane will not
roll over into the raised wing, just sits there and falls at about 1500
fpm. This helps to keep my ass current in flying the plane. I try and
make about half my landings from about a mile or mile and a half final
at a few mph above stall without looking at the airspeed indicator.

During primary training, many moons ago, I was growing frustrated with the
sedate nature of our flying, so I asked my flight instructor (Bob -- a guy
with 20K hours in every known flying machine) when we were going to get to
the "fun stuff"? He didn't know what I was talking about, so I told him I
wanted to see what these things could actually *do*...

At which point he smiled that crooked smile of his, and proceeded to do a
wing-over with a recovery out the bottom, going the opposite direction! I
was whooping and hollering for more, but he just went back to our lesson for
the day....

Nowadays, Mary and I are very cautious in our Pathfinder, rarely exceeding
45 degree banks, and never pulling more than mild G turns. Mary hates steep
banks (except in a Super Decathlon -- then all bets are off!), and the most
rambunctious thing we ever do are "Up-Downs" (as the kids call them), which
is a firm pull up with a steady push-over at the top that induces negative
Gs in the back seat.

Just curious -- what do you guys do with your spam cans? I've seen video
from inside a Cessna that shows a guy doing some pretty radical maneuvers,
but in real life what's the most you push your aircraft?
