If the tail looks a bit out of place, and I'd argue that it does, that's not a bad thing. The tail is, in fact, the component that symbolizes the evolution of the design from a "keep it simple, stupid" box to one that has become a surprisingly sophisticated response to the fiendishly demanding strictures of the latest revisions of Part 23. Designed using the latest computerized tools and tested and tweaked in consultation with the National Test Pilot School, the tail is big — to stop a spin in its tracks — strong and, to tell the truth, kind of pretty. Its dramatic sweep and additional side area were both features intended to give the Airvan the most docile stalling tendencies imaginable in such a big single. While the conventional tail looks oversize on the longish body of the somewhat awkwardly proportioned Airvan, it suits the airplane's aerodynamic needs to a T, so to speak. Still, the result is an airplane that appears to have been designed by committee, each member putting forth his own agenda, the fruits of that motivation being the oddly assembled shapes and sizes of the various Airvan components.
