What, and miss a perfectly good chance to pull the chute? I don't think anyone has ever glided a Cirrus anywhere.

Pulling the chute in a Cirrus(or other aircraft is not something one should just do and think that it will be an enjoyable ride. The landing might be very hard, hard enough to hurt your back. Cirrus will of course say that your life was saved but maybe your back was hurt. I might consider landing in a nice field if the engine failed but that could result in injuries as well. I wonder if it would be better to glide to an area over trees(if that was an option) versus a field and then pull the chute. Maybe not, but no option is perfect.

"Once the large chute deploys, the descent rate is about 1,700ft per minute (518m) – so the impact you'd expect on the ground is equivalent to “jumping from a 4m tall ledge,” says Travis Klumb, Cessna’s director of flight operations."

The Cirrus also has sacrificial legs that will crush to absorb an impact with ground, so that 4m jump from a ledge would be more like a 4m jump into a big leaf pile, or onto a stack of cardboard boxes, or something like that. It's still going to hurt, but probably not fatally.

As I recall, Cirrus explicitly recommends to pull the chute early at the first sign of trouble as opposed to as an absolute last resort. The last time I flew with a fellow who was Cirrus trained, pretty much every emergency procedure was the same. All he practiced was this quick-draw motion on reaching for that lever.

I think buying a cirrus and pulling the chute is creeping up on my, "Just hit powerball." to do list.

Great way to sell new airplanes to existing owners!

Yeah, you pull the 'chute, and Cirrus gets to sell another plane. In the meantime, yours has impacted the surface, perhaps not where you intended. Just the other week it was reported that a Cirrus under a 'chute killed several unsuspecting people on the ground. We pilots do not have the privilege of putting unsuspecting citizens at risk, because we elected to surrender control of the airplane we are flying.

I've considered this as well. A chuted cirrus will definitely cause damage, but are the odds really that bad for injuring or killing people on the ground? It is a fairly light construction on a parachute descending at 2000 ftpm. That's 36 kph. The majority of cars drive faster than that in a school zone. Granted, it can be fairly unexpected to have an airplane drop on you from above, but it should be easier to avoid than a car.

The alternative could be crashing that same plane at 160 kph in a house or beach where people are present.

Anyone from transport reading?

These things need a chute activated klaxon.

The point is to control the plane so as to prevent collisions with people on the ground. To control the path of the plane, the plane must be controllable. It's certified to glide, so glide it away from vulnerables, rather than drifting into them out of control.

Glide to somewhere uninhabited and pull the chute there.

Like this:

No harm to people on the ground, I guess it's up to the pilot if they'd rather roll out, or thump on!

If you rolled it out, you'd have to answer as to why you deviated from the emergency procedure.

In the picture above, it probably would have been better to glide it in. However it doesn't seem like the flight manual emergency procedures allow that flexibility.
