There's a video floating around the internet of a golden lab doing
something like that.

Ask and ye shall receive.

Am I insensitive for laughing my ass off at this one and watching it over
and over? That's the funniest video I've seen all week.

I showed that manuever one time to a pretty redhaired girl I'd just started
dating, who was wearing a really nice white coat on a cross-country one
time. I forgot she had a Dr. Pepper in her hand.

Oooopppppppppps! Sounds like something I would do, or should I say, the
kind of mistake I have made.

What's the best way to fly a zero G parabola? My kids are hooked on them and
they're actually learning some science from it. I'd like to get a little
more duration without getting too fast.

I usually do a little climb until the speed bleeds off some and then push
over firmly. Should I pull the power over the top as I'm pushing?

Been a while, you might want to get some acro instruction to really
perfect it, but try this.

Dive so your airspeed is 10-15% below redline. You want enough energy
so that you can get established on a 35-40 degree upline. Once you
get the energy, begin a smooth 1.5-2.0 G pull so you're established on
the upline. Your airspeed will bleed off rapidly, even with full
power. As speed decays towards Vs, reduce power to idle while
smoothly unloading the wing. You want to float over the top with the
airspeed as close to 0 indicated as you can; remember- at 0G the wing
will NOT stall.

Yes, but unless you're going straight up you will not be able to get
anywhere near 0 IAS at zero G.

Now there was me thinking that stalling was only due to too high AOA...
Do you mean at 0 IAS?

Oops.

I had a similar, but less messy, incident once. On the first push
over, 30 years of dust and dirt flew up. It was IFR in the cockpit.
Fortunately, she had a sense of humor about it. Her purse migrated
from her lap, over the back seat and onto the hat shelf.

Your acceleration is fixed in a parabola. It is always exactly -1.0 G, which
precisely negates the pull of gravity and gives you the zero gravity
objective.

Clueless as usual.

A zero-G parabola is a ballistic trajectory; it always involves acceleration
towards the ground (in the direction of gravity) at exactly 1.0 G. That's how
it produces the "zero-G" effect.

This being so, you cannot change the acceleration of the aircraft along the
vertical axis without losing the zero-G effect.

Essentially, if you fire a cannonball next to the aircraft, your aircraft
needs to follow the same path as the cannonball in order to become
"weightless."

Obviously,,, but it still has "zip" to do with reducing power to avoid
accelerating excessively in the dive.

Accelerating excessively would destroy the zero-G trajectory.
