Last time I looked the main gear on Jay's airplane was attached to the
wing. The spar is still taking the load.


Oops! Thought he drove a 172...


Insult, injury... Ouch!!! Ooooh thats just mean, man...

Yes, one should not insult Cessnas in such a crude manner! :-)

As another reference point (and a crude way of measuring the negative Gs), I
routinely read about guys doing the "up-down" maneuver to the point where
their engine sputters due to fuel starvation.

I've done that with Cherokees since the 1960s. It doesn't hurt them
at all. And it is a wonderful way to teach the kids about physics.
It's called a parabolic arc and it's not an aerobatic maneuver.

Since that flight I've carefully
inspected the empennage, and there is obviously no visible stress or strain,
or I wouldn't be flying it -- but how can you really know without extensive
metallurgic testing?

Think about it Jay. When you're just flying along, there is a large
load on the the stabilator forcing the tail down to make the plane
stable (hence the term). When you "unload" the stabilator you've
given it a nice little rest.

I knew a pilot with a Commanche that put 50 pounds of lead in the tail
cone. It made it go faster. Really not that much faster, but the
plane flew better. That was also a long time ago! And I loved flying
that Commanche.


If you've ever looked at the stabilator attachment on a Cherokee you will
marvel at the simplicity and apparent fragility of the design, so inducing
excessive negative-G is something we never, ever do.

Don't ever look closely at a helicopter.

How about spinning it?

Did you mean to say intentionally?

My airplanes say that "no aerobatic manuevers, including spins, are
approved" so I don't do any aerobatic maneuvers or spins.

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?

Not a good idea. Even Cherokees take a lot of altitude to recover
from a spin.

And for you die-hard Cessna fans, don't EVER look at the wing spar attach
points... You'll never do a steep turn in your 172/182 again!

I was being facetious. Did he do a W&B on the thing?

I have. What is the problem? :-)

Well, to my (admittedly un-trained) eye, there doesn't appear to be enough
"there" there...

Each 10,000# engine on the B-707 was attached with three (3)
bolts the size of your small finger! Never lost one.
