SR22 YD warning

[Bert Pieke 7,585]

I just took the new Cirrus for a spin, handflying all the way..  When descending I got a yellow YD warning on the PFD..

Is that a feature, or a bug?

I think the blinking yellow YD is just letting you know it has turned off which should occur on final. It's automatic in this plane if I'm not mistaken.

Does the pitch trim work? I tried moving the large button on the "yoke" with the mouse, but nothing seemed to happen that I could see on the trim pitch indicator. What should I be looking for?

Thx,

Al

No idea... I did not touch the trim..

I never turned on the autopilot... would you expect the YD to engage even when handflying the plane?..

Yellow flashing YD annunciator means YD disengagement.   It will do that automatically at 500' but there are other circumstances where the automatic YD will disengage; including heavy rudder pedal movement and crosswinds in excess of the aircraft's published max.

Yes.   The SR22 G6 has fully automatic Yaw Damper.  It engages at 500' and disengages at 500'.  Even in manual flight.

Thank you! Very interesting! 🙂

A feature, it is!

Yes, I think the automated Yaw Damper in a GA aircraft for manual flight, was a first for Cirrus. 😎  Pretty cool!

Can anyone explain how the Cirrus SR-22 pitch trim indicator works -- what should I see changing as I adjust the pitch trim? I see the pitch trim scale on the Control Stick shaft, but I don't see anything changing as the pitch is changed.

Thx,

Al

Right now there is no specific indicator, you just trim by feel.

The the real SR22T, there is no aero trim; instead, there is a control force bias introduced in the control stick when using the trim switch. Unfortunately, this doesn't really have any good sim analog as the sim doesn't support this style of trim, and also since user sticks cannot have their center point dynamically mechanically biased in one direction or another, which creates a number of bad mapping situations. Additionally, this can't just be applied as an animation adjustment since that would break the controls in VR.

As such at the moment the control stick will not move when the trim is adjusted.

Well thanks very much for the explanation, Matt. So in the real plane the scale on the Control Shaft is in effect a trim indicator since the Control Stick neutral point will adjust in response to the trim control force bias. Interesting. Given the RW cost of that plane (~ $800K+) I'm a bit surprised there isn't a trim indication on one of the glass displays.

Thanks again,

Al

The Cirrus is an extremely capable cross country machine, especially the 22T with FIKI. I have a love/hate relationship with it, though, as it is not a great “hand flying” plane. The control surfaces are spring loaded to return to their trimmed positions so you very much fly this plane with trim. As Matt says, other than trimming ailerons neutral and elevator in the TO range for takeoff. It’s all trim by feel.

As for the automatic YD, it disengages at 200 feet AGL.

They are well over $1M now (new). There is no need as the trim indication is (black hash marks) on the metal shaft, which is in your peripheral vision. You calibrate it to center before T/O. It works well in flight and really best used by feel.
