Looping a standard cirrus

Who has done a loop in a standard cirrus? Any comments or hints. Currently getting some acro training with the goal of looping my cirrus.

I do not believe the Standard Cirrus can be looped safely. Don't try it, or the world will spontaneously combust and all life will end.

Flight manual predicts the end of life as we know it maybe!

The glider is rated for loops. Entry speed 97 knots. Im just wondering if any other cirrus owner frequently loop and how it behaves

The Cirrus may have been rated for loops when it was new and free of repairs, control slop, etc. so unless your 40+ year old glider is in pristine condition with no accident history you will need to take all those approved maneuvers and Vne with a pinch of salt.
I would not try it myself.

A loop means entry speed of about 100 kts and pulling 3-3.5 g.
If you don't think you can do that with a certain glider, that glider is probably not airworthy in the first place.

I like the statement: "The sailplane enters into a spin from a sharp stall applying full rudder. The control stick should be pulled during the spin."

So, are you to remove the control stick if you enter a spin? :-)

Hey Steve,
I think I get (and appreciate) your joke,
but For my own safety, "pulling the stick" is to intentionally induce and maintain a spin, Correct?

I think something is lost in translation, but I believe the manual is saying you need to keep the stick back to keep the plane in the spin. Relaxing back pressure may lead to a spiral. It says recovery is done by easing the stick forward, and applying "slight opposite rudder". Both implying not full motion of a control. Not having any Std Cirrus experience myself, I would defer to someone who does have this experience.

Hopefully it is dual controls so someone else can recover, you have a chute, you have enough altitude so the aircraft saves your butt........
