Hi All,

I have noticed that each time this subject is broached, there seem to
be many who are perturbed by the idea of electronics/software assuming
a primary role (control, stabilization, etc.) in GA aircraft.

There are some who believe that electronics and software are sorely
underutilized. The electronics that are used are mostly employed in
an ancillary role, like providing data to a pilot, etc.

There are others who feel that electronics should be fundamentally
integral to the design of the aircraft from the start, meaning that
any potential opportunity for use of electronics should be employed,
as it is almost always the case that digital version of a mechanical,
analog part is better on many axes, including weight, cost,
reliability, controllability, etc.

Ken Tucker mentioned a rotary wing aircraft for his project. I have
not specified what type of propulsion mechanism I have in mind for my
project. Both of us feel that electronic, fly-by-wire is the future of
aviation.

What do you think?

1. Do you think that current GA aircraft use not enough electronics?
2. Do you think that current GA aircraft use too much electronics?
3. Do you think electronics should retain a peripheral role ? (Garmin,
etc) but not be used in control paths (fly-by-wire)?
4. What role will electronics play in aicraft designed in the year
2108?
5. What will the aircraft look like in 2108?
6. Any other thoughts...

Here is an excerpt from a concurrent thread, where the conversation
seems to be turning toward Electronics-Or-Not:

The notion of first principles, like some of the conservation laws,
seems to be lost on Le Chaud and others. He calls himself an engineer,
but seems not very familiar with Newton, or concepts like energy
density when talking about a prime mover, or. . . but why go on?
Austin has its village idiot.

Lots of guys like that. The idea that electronics can somehow
make an airplane lighter and faster and better, all at once, is just
an obsession with electronics and computers. The idea that electric
power is green is another falsehood; where does most electricity come
from? Hydroelectric dams (devastated valleys), coal (dirty), natural
gas (CO2 and an increasingly limited resource), nuclear (dangerous and
waste problems), and so on. Hydrogen fuel cells, even if they worked
well and were affordable, require hydrogen, which requires the
electrolysis of water, which needs vast amounts of electricity. Other
methods of storage involve heavy metals and their dangers. The idea
that a helicopter is easy to build (with biplane blades, yet, which
was tried in the early years of 'copters) just reveals that the writer
knows nothing of the problems that gyroscopic precession present to
all rotating components of the helicopter, to say nothing of the AOA
and airspeed variations of all rotor blades during flight. Helicopter
flight is appallingly complex and it's a wonder it happened so soon
after fixed-wing flight (35 years or so).

Here is a frightening thought. If Le Chaud is in fact an engineer,
someone is paying him money for his lack of knowledge of basics, like
the power demand to keep a something with a specific gravity greater
than its environment suspended there. Well, that may be second term
physics. Lift ferries indeed.

I wonder how long it would take me to understand his true worth -- I
do make mistakes in hiring, but rarely in discharging.
