I think firstly any product marketed to bypass the "old anorak" portion of the GA customer base is going to draw criticism from the traditional people.
Some of it justified... morally, IMHO, you should not market a plane like you market a car, because they are worlds apart in actually deliverable A-B-transport utility value with a bare PPL, and only just about on the same planet with an IR. And that is in the USA - the earth's GA heaven.
There is also a gulf between the legal level of pilot training, and what I think is required to operate the fairly advanced avionics systems in modern planes. This will result in many people flying these things with a deficiency in systems knowledge which is likely to become significant as soon as the s*** hits the fan. But that applies to anything modern, not just a Cirrus, because you can't give away a plane unless it comes with a G1000 (or similar).
The provision of the chute also draws criticism because many people seem to believe (I don't actually think they do but it seems like it) that a pilot who makes a major error should die. And he should die while saluting to The Queen whose picture is pinned to the visor.
And not just the Queen; I know of an American GA pilot (ex military, fairly predictably, and massively proud of it) who hates Cirruses so much he joined up their US user forum and slagged them all off, before having to get out of there. I once googled on his name and found so much stuff...
I would have the chute if I could get it, because it provides a backstop for an engine failure over a forest or mountains, or some slightly bizzare emergencies. But I would never pull it above flat country.
Alan Klapmeier feels strongly that we need more people in aviation or we will lose more airports and GA will go away
He is absolutely right. Even in the USA, it is widely reported that the Oshkosh visitor demographic gets a year older every year.
My wife hates all planes that only have one door. Being able to step right into the seating area is a big deal to her
and likewise for a lot of people - once they have tasted the "2 door lifestyle"
I would never go back to a single door.
