What is with the Americans and the twin tail on their aircraft? (Not just this aircraft)

Its not a 'Twin tail', it's a 'V tail' or 'Butterfly tail'.

The advantages of this set up are that you effectively have 2 control surfaces (wings + ruddervators) as opposed to 3 (wings, fin, tailplane), thus you have less structural weight. More important is the reduced surface area leading to less Induced and Parasite Drag (although NASA studies question this since a V tailed a/c tends to require a larger tail than does a conventionally tailed a/c). Additionally the reduction of intersection surfaces from 3 to 2 produces a net reduction in drag through elimination of interference drag.

Also in the case of the Cirrus, having a V tail means that the tail surfaces are clear of the jet efflux.

The disadvantages are that when yawing, the V tail produces an excessive rolling moment, coupled with a higher likelihood of overload failure.

- except overload failure certainly a risk in the very low percentiles given the technology and testing put into this machine?

And I do hope lots and lots of private jets are bought and clog up the airways; given the amount of space GA is being left down here near the deck maybe the powers that be will finally give us back more sky to fly in so GA jets then won't bother the companies up at the high FL's. Guess who is bored to tears with commercial aviation getting all their own way........infact I may well take a few more FL trips to annoy people Best take my asprin now before the heart goes.....!

One would hope so given modern materials technology!

The fact remains, however, that the loading on a V tail will always be greater than that on an equivalent conventional tail.

WRT GA I feel your pain. I flew to Staverton last month on 'Project Propellor'. It felt really odd bimbling around at 2000 - 2500 ft QNH. My head was in swivel gear since every other bugger and his dog was at similar altitude.

-was offered a deconfliction service flying VFR down to Daymns Hall recently, such was the number of aeroplanes in that piece of airspace at 2000 ft-ish. so load up the airways with GA jets please
