Agree with you wholeheartedly on the parts count and fuel shut-off.
I also have a fairly libertarian view of how intrusive I like my government to
control my life. The unfortunate reality is that government, insurance
companies and lawyers (also include heirs and estates of careless or reckless
pilots) do control how we build and operate our planes. Unless you are content
with blazing along in the evershrinking class G airspace we are beset by a
myriad of regulations which dictate what equipment we put in our planes. Fly
IFR and add another layer on top of that.
Designs are to a large extent predicated by economics. First planes must be
desirable to potential purchasers. Unfortunately they must also be safe. SOme
of the planes which are the most romanticized are some of the most unstable. The
concepts simply fade away; witness the GeeBee. Unless we're prepared to lay out
every dollar that it takes to build our planes, forget about getting financing
or insurance on a design that is "unsafe" or perceived as unsafe. The
definition of unsafe is not determined by we builders, debating whether or not
to install fuel vents, but in practical application. What causes airplanes to
crash and what causes manufacturers to be sued by the previously mentioned
lawyers, decedents, heirs and estates. For proof of this concept, just take a
look at the new Cessna 172 with its 13 separate fuel sumps!
Safe planes equal attractive planes, which leads to volume sales which leads to
the ability to employ high volume high quality production techniques which
lowers costs which makes the planes more attractive, repeat the cycle. Lack of
volume leads to lack of funding which leads to bankrupt plane manufacturers.
We're not going to sue or regulate our way to safety. The market and darwinism
will dictate what planes and what pilots survive.
