Software doesn't make airplanes fly. And as I mentioned I think this is

can guarantee is that no SOFTWARE is going to be written in the next 10
years or ever that is going to make current hardware able to fulfill
your idea of a PAV. There are a lot of very smart software people out
there and there are also a lot of folks who build homebuilt aircraft.
There is bound to be a subset in there of the two and none of them have
done it.

I have scoured the web for these homebuilt craft, and most of them
conform to the tractor model, which automatically precludes many
possibilities, even the ones with folding wings.

I'll repeat there is no way SOFTWARE could make current technology do
what you want to do. If you think I'm wrong prove it. It is up to the
person making the wild ass claims to do so. Otherwise your are asking us
to prove a negative and we can't do that.

What do you mean by "current technology"?

Do you mean taking a standard aircraft or kit and adding software to
it? If so, I would agree that software will not help here. As
mentioned before, a $100,000 plane, it would be impossible to take
something that already costs $100,000 and add more to it and make it
cost less than $100,000.

A systemic approach must be taken, one that does not presume the pre-
existence of the $100,000 aircraft as a base. A different dollar
amount would have to be sought, perhaps something in the $40,000-
$50,000 range. Naturally, this would automatically exclude the
possibility of pre-built aircraft.

So, if "current technology" does not mean the $100,000 tractor-model
aircraft, but something else, which might or might not use the
fundamental components of the $100,000 aircraft (steel, aluminum,
plastic, gears, RAM, capacitors), software could help immensely. For
example, one thing that could be done is to eliminate the ICE, which
would obviate many other expensive components.

It's likely computer assisted controls would allow ga airplanes to be
flown safely with center of lift and center of gravity coincident. For
airplanes with otherwise existing technology that might be as much as
a 10% improvement in range. There's another few percent, but only
that, with pusher propellers. Both of these 'improvements' have not
overcome serious counter arguments.


Start with people who are concerned with most effective/efficient
airplane configurations, those beautiful things called gliders. Long
small chord wings, laminar everything, and if you want instant
funding, talk to them. Give them a 30% reduction in drag and money
will flow in.

But you can't do that. You're all type, you have given no evidence you
can do more than that,

I've done some serious research -- REAL research -- on pilotless
extended range airplanes flying at 500 km/hr or less, and can't find
anything that approaches a 20% improvement over the drones the air
force is flying now. Maybe a new Skunkworks is out there doing
something (or maybe Scaled Composites is -- now that is serious
competition!!) but a maybe EE from maybe Austin (there is a Paris in
Texas) who has demonstrated no skills is not where I'd choose to place
my bet.
