Default Looping a standard cirrus

Oh come on, If Bruno can do it... Finish your Aero training and go for it, whats the worst that can go wrong? Wings or elevator comes off? Tailslide? Thats what your parachute is for BTW, practice getting out in all conditions and go for it, the glider IS certificated for the maneuver, what could got wrong? Pilots do loops all the time.

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.

I believe the joke is, "pulling the stick" as in.......removing it.......

;-)

Yes, most aircraft, pulling the stick either deepens the spin, or, (sorta worse) makes it a spiral.
Big difference between a spin and a spiral is that a spin will usually stabilize until you escape it, recover or hit terrain. A spiral may mean you "remove the wings" as you either exceed VNE or G loads, possibly BEFORE you hit terrain.

I believe I get the joke.

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

I have looped an early, all-flying stab Cirrus, Mini Nimbus, and Janus A. Seriously locked down my control hand/arm on my leg as the elevator stick pressure in all of them is pretty neutral and it would be pretty easy to pull too hard.

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.


Hi,

I would recommend good training before trying to loop the cirrus, as the cited entry speed of 97 knots is quite near to VNE of 119 kt. Very easy to get out of it with a lot of speed.

Don't do it without a G-meter installed.

Regards
Stefan

Looping the Std Cirrus is very straightforward, and no different to looping
any other glass glider.

If you're competent to loop *any* glider the Cirrus should be no problem

(If you can't maintain speed within 20% of your target (97kts vs 118) then
you should probablyy give it a miss)

Default Looping a Standard Cirrus

I never understand why people loop gliders designed for competition. Grab a club 21 or Grob or something less slippery with a bigger spar and have fun with that. Or even better, pay to go up in a Decathlon with an instructor and actually learn something in the process.

All that looping a slippery glider gets you is an awful butt-clenching sense of "Oh **** Oh **** Oh **** Oh **** Oh ****" as your eyes jump between the bending wings and the clockwise acceleration of the ASI.

Looping a competition glider makes as much sense as turning the engine off on a Pawnee and trying to soar it. In both cases, you're using the wrong tool for the job.
