First thing would be Bluetooth headsets... no more cords tangling round
the cockpit.


That would be pretty nice. But now you need batteries in your headset to
power the audio amp.

Yeah. I wonder whether head movement would produce enough power... like
the 'self-winding' watches of the 1970s.

Next would be various engine instruments... EGT, CHT, etc.

I guess you'd need some devices (i.e. wires) for routing the signal through
the firewall or around it. How much lighter would this be than, say, a
twisted pair for CAN?

Not necessarily... I guess you're talking about a metal firewall
shielding the signals, right? But, assuming a fibreglass cowl, mount a
self-powered repeater someplace where the engine instruments can see it,
and where the instrument panel can see it (e.g. a bump on top of the
cowl, on a wingtip, on the leading edge, on the landing gear perhaps).
An extra benefit is that you no longer need (as many) penetrations
through the firewall.

Maybe move the entire radio receiver out to a wingtip or somewhere well
away from the engine's RF noise.
But I can't see that being self-powered.


The receiver could be, but not the transmitter. An antenna wire is probably
a lot lighter than running power out, so I guess that would need to stay in
the cockpit.

Well, I did suggest (kinda tongue-in-cheek) using RF to power the radio
transmitter, as Nicola Tesla proposed way back in the (IIRC) 1930s.

Yeah, I know that none of these things is quite right, right now.
There's lots of engineering to be done to make it workable. But I think
we *probably* have enough technology to be able to begin implementing
this kind of stuff.

I'm typing out loud here...

When I suggested bluetooth the other day, what I had in mind was a kit
that you would temporarily hang on an airplane for specific tests, much
like we hang all the orange on Navy aircraft for flight tests. Much more
accurate pitot-static, vib sensors, postion sensors, data loggers, etc.
You could, for example, have a kit for flight testing an RV-8. Pop it
on, do the tests, and remove it. Or it could be used for "external
stores" such as a camera.

Afterward, I contemplated replacing all signal wires with wireless. So
any wire not carrying power could be replaced. This might be especially
useful for a refit, where access is far more difficult than during
initial construction.

Other harebrained ideas...two planes in semi-close formation could
network via bluetooth. Why? Could be low prob. of intercept comms on a
private channel, sharing of nav data, text messaging, ipod music files.

There's an ongoing thread on rec.aviation.soaring on bluetooth and
cellphones aboard planes.

So was the internet for a while.

I'm thinking of just wireless in general, of which bluetooth is an
implementation (with a really catchy name.)
