What about attitude and heading?

You still need sensors for attitude and heading. You also need sensors for
engine and fuel parameters, and so forth. Somehow, you need all those to
interface with your PC's flight instrument display (displays?).


USB. I think it would be highly appropriate for this type of
application. Theoretically, you can have up to 127 USB devices
pluggged into the same USB card on a PC. If you put multiple cards in
the PC, then you can have even more USB devices. Since the required
bandwidth for temperature sensors is very low, It is conceivable that
one USB PCI card could drive the entire control infrastructure of the
aircraft.

The design would probably entail a redundancy model where one PC
motherboard acts as a secondary to the primary controller. Windows
supports multiple displays, so you could have 4 displays in the
aircraft. One for each passenger, with radio, music, DVD's.

I think this model is the same thing that Boeing/Airbus & friends use,
only they probably get charged 10-20 times the cost of what they should
be paying.

Is that French for "hot rabbit"?

Yes.

Long story short, I visit France each year, and the first time I was
there, I found an advertisement for a French movie - "Le Chaud Lapin".
See:

http://www.moviecovers.com/film/titr...D%20LAPIN.html

When I murmured it out loud, there happened to be young French women at
the party who overheard, and so that became my name thenceforth, even
though I am neither hot nor do I bear any resemblance to a rabbit.

It's way too easy to trip over the cord with USB -- or to have it
vibrate loose. My experience with USB indicates that it isn't reliable
enough for my servers at work, it's not good enough for any airplane I fly.

Maybe if you replaced the connectors or soldered everything well....
But, I'm reluctant to suggest USB to my users for anything more
permenant than a mouse.

Er, I meant to say that it might work if you soldered everything or
replaced the connectors. My post-writing editing made what I was trying
to say unclear (though better organized!)

There is already an adequate standard buss for interconnecting avionics
devices. I'm sure you can purchase a PC card to interface to that.

But you're on the right track. Non-stop, fault-tolerant computing is
the issue.

The Space Station uses IBM 760xd laptops for their glass cockpit.

Well Ted, that's hardly a cockpit and I doubt the space station is going to
have to navigate in the clouds anytime soon or with anybody on board.
