Let me ask a question, using the Cirrus as an example, or a similar TAA aircraft with similar stall speeds and characteristics.
If you put an average PPL in that aircraft, with his loved ones four up, full fuel and did a random test at 2000ft over the UK where without warning they had zero power?
What do you think the success rate would be per 100 aircraft of complete success and no injuries to the occupants doing a traditional forced landing?
Who knows but I would expect 80% optimistic and at the very least 20% may not survive and probably more fatalities.
In my opinion and best guess if in the same scenario the chute was used I suspect the success rate would be in the very high 90's but I doubt 100% but it would be more likely to achieve 100% success with the Chute than either your average or for that matter your very experienced Pilot.
That is entirely why I have reached my decision.
