I don’t have a cirrus (or manual) yet, so I am curious what Cirrus has to say about what situations warrant using the chute (or do they say?).
Being in FL and planning to do a lot of Bahamas trips, I can see where I would rather use a chute if the engine quit over open water than attempt to ditch in 4-6 ft seas and catch a wingtip or wheel and end upside down or looking for my nose on the dashboard. I wonder what the odds are of the plane sinking in either scenario?
Certainly, loss of control should be a good reason for deployment.
What about a night-time engine out scenario? I think that if I didn’t have a place to land such as a highway (without power lines) that I could identify, I would have to consider the chute. Day-time over land engine out over ugly terrain sounds like time to say “chicken” too.
Any other thoughts on this, anyone? I hope I am not beating a dead horse. Haven’t been following the forum long.
I think all of the circumstances you describe are appropriate for use of the chute. I am still waiting for the POH on the SR22, but as far as I know, there are no specific instructions as to the circumstances for use of the chute as distinguished from instructions as to how to deploy the chute.
Use of the chute will “substantially damage” the aircraft on landing. I recall that at the 2000 A.O.P.A. convention Tom Bergeron quipped that you could get an interview on “Good Morning America” if you were the first to pull the chute. The price seems a little too high for fifteen minutes of fame.
As to ditching at sea, the odds are certain that the aircraft is going to sink. The only question is how it is going to contact the water. I agree that a controlled vertical descent on a chute is preferable to trying to “land” the aircraft in rough (or even smooth) seas. Ditching at sea, I can’t see any reason not to use the chute. The aircraft will sink anyway, so there is no reason not to use it.
Hopefully, none of the circumstances you describe will ever take place. Realistically however, sooner or later someone will find himself or herself in one of the circumstances you describe and will be talking about it, hopefully not even from a hospital bed.
If you look through the earlier posts, you will find a thread regarding the chute. That discussion was mostly on the issue of “why put a chute in the aircraft” rather than “what are the circumstances for the use of the chute”.
If someone has some more specific information from the SR20 POH, I would certainly be interested in what the POH says about circumstances as well as the method of deploying the chute.
