...regulatory barriers suppress the adoption of new technology. For

instance,
most FAA-certified aircraft today are still the same aluminum-and-rivets
construction pioneered more than 50 years ago, while for at least a

decade
non-certified experimental aircraft builders have preferred composite
materials, which make their aircraft stronger, roomier, cheaper, and

faster
at the same time.


I think that this is more a product of the cost factor than regulation.


And where does the "cost factor" derive from?

The Semi-Monocoque construction ("aluminum-and-rivets") technique is
defiantely antiquated but is still the most cost effective method of
producing a lightweight faired structure. Composites, while very
effective in reducing weight and increasing the strength of the
airframe, are extreemly difficult to work with, both in the
manufacturing stage and during life-cycle maintainance (de-lamination
anyone). Also the cost involved far outways the advantages, from a
production point of view, in the general aviation sector at least.

It should be noted that some of the most inovative aircraft in recent
times have not been overly successful. A prime example is the late
Starship. Ruthan's Scaled Composites company have also produced some
very advanced aircraft but these have seen limited appeal.

One should also bear in mind that the older cessnas and pipers which are
the mainstay of the GA world were designed with a 30 year life-cycle and
are still going strong. And the popularity of vintage string and fabric
aircraft is ever increasing.


So, what you say is "the hell with innovation and new products"?

Interesting.

Maybe we should go back to 13" B&W TV's?
