The Cirrus I fly for fun (Airbus captain) can do 210 knots at FL250 and would not usually be considered a training aircraft. In my experience it is a stupendous personal transportation device. But it does have some quirks, for example the power management takes a bit of getting used to. It is not single lever like a jet, but has a mixture control which needs to be used carefully to avoid cooking the engine. The accident aircraft was according to reports a rental and it will be interesting to know the experience of the pilot. The great thing about this event is that everyone survived unscathed and can tell their story. Hopefully we can all learn something new. But I would be surprised if there were not some man machine interface learning points, similar to some of the issues with Tesla cars currently, (in particular understanding the limits of automation / modern technology).
