Zero G profile

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.

The key is to be smooth. Make sure there's no loose objects in the
plane; nothing sucks worse than having a pen lodged in the controls on
the downline. You may want to get instruction from a QUALIFIED acro
CFI.

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?
