As one twin-jet and quad-jet driver, I comprehend it. I've spent a significant number of years at low altitudes in the mountains in single and multi engine airplanes. When I say low altitudes, I mean close to the terrain between 5' and 200'. Much of that terrain has been on fire at the time. I don't know how many "twin jet drivers" will respond who have experienced not only engine failures in mountainous terrain, but off field forced landings as a result, but I'll respond, having done all of the above. More than once.

I appreciate the notion that a single engine piston airplane ought to be reliable and probably won't fail, but that's a notion that could only be endorsed by someone who hasn't experienced it, and for whom the concept of making a forced off field landing in mountainous terrain is only an academic query.

I flew 207's quite a bit, in some rough country. I had an engine failure in one. I flew single engine piston and turbine aircraft in rough country, and had an engine failure in both single piston and single turbine aircraft, resulting in forced landings.

Personally, I don't do single engine night, IFR, or IMC, though I still do a fair amount of single engine flight in the mountains. Unless someone is fully prepared to make an off field landing in the mountains, I strongly suggest refraining from flying singles in the mountains, and unless one is operating a twin that's capable of an engine-out at high density altitudes, has known ice capability, and good redundancy (a twin with a cheap vacuum manifold on a light piston twin really isn't), there may be better roads to Rome.

As for the Cirrus aircraft...their chief claim to fame, other than automotive decor is the CAPS parachute, which far too many treat like an alternate airport. It isn't. It's also not a suitable substitute for good planning, which doesn't include single engine IMC over the mountains (or a flight by someone who can't execute a forced landing without the parachute...in other words, it ought not be used as a crutch by those who lack the capability, ability, and basic skills). CAPS is an emergency system that should not be used as a shortstop for bad judgement and lack of skill.
