You need wiring looms for wire...regardless of what protocol(s) are running across the wire.
So-called "fly-by-wire" has reduced the analog control wiring, but passenger comfort has actually *increased* the amount of wiring in these looms. Things like seatback phones, and audio-visual systems saw to that. Oh, and the new Internet connections on some carriers will only add to this.
As for networks, there are generally several types of network in commercial airliners. You'll even find Ethernet on many (often over fiber as opposed to copper).
Well, you're aware that there are aircraft that run Windows, right? (I wish I were joking...I can remember if it's the 777 or one of the Airbus models).
I was delayed on the apron once while flight crew rebooted...again, I am NOT joking.
I was drawing an analogy that just about all vehicle manufacturers do the bare minimum to meet regulations (and why would a business do anything more, unless it could be parlayed into a feature?).
Incidentally, cars like the new BMW 7 series or Audi A8 have much more in common with aircrafty control systems than you'd think....and losing control of your BMW 760i on the autobahn at 200km/h because Dieter is playing on his Gamebody is also a concern;-)
See my other reply to someone asking this, it's not the cockput that's the issue...it's the wiring looms that run all over the aircraft that end up acting like RF antennas.
It's not actually the cockpit that's the issue....think about it, the wiring looms in aircraft (ever seen just how much cable is running around your average aircraft) act like by RF antennas.
There are definitely ways to achieve better RF immunity....but, alas, aircraft manufacturers (at least civillian) often do the bare minimum required by regulators (just like car manufacturers generally do).
Attach a GSM/GPRS modem to the host that sends out the messages! Not only can you then send SMS, you could also conceivably get an IP connection to the send email through another service....which narrows down the issues with SMS latency.
You *do* have a phone that can get SMS, don't you?;-p
I meant GEM didn't do much...I did LOTS on my Atari, including my first introduction to a digital recording studio! Even today, there are STILL musicians who use Ataris (Far Boy Slim is one).
I thought the GEM desktop and mouse for my Atari were pretty damn cool...even though they didn't really do much, made me feel like I was on a "big computer";-)
Actually, looking back, it's amazing to see how little has changed in 15-odd years!
Apple had an appauling track record with Java until fairly recently, but OSX is a seriously nice platform for Java development now....at least for me:-)
I do surface mount stuff at home all the time...it's not nearly as hard as most people make it out to be! It's quite easy to solder a TSOC, SOIC8 or SOIC16 component onto a breadboard adapter (I make my own).
And just about everything Microchip (the PIC folks) make is available in DIP;-)
I've been using Jave modules for a while...both from DalSemi/MAXIM (the "TINI", http://www.ibutton.com) and Imsys (the "SNAP", http://www.imsys.se).
They provide a JRE environment (JDK1.1.3 in the case of TINI, J2ME CLDC 1.0 in the case of SNAP) and allow me not to worry about processor and memory design etc.
Right now, my SNAP module lives in a custom extuded aluminum enclosure I designed, and has a MMC interfaced for it (an extra 16Mbytes of removable storage), and a bunch of other things like temperature/humidity sensors, LEDs, an LCD, and dry contact sensors.
One reason I like both these modules is that they support I2C, SPI and 1-wire for expansion....meaning that you don't have to necessarily hang stuff off the CPU's data bus.
The electrons are used in a similar manner to those bouncing ball 'executive toys'....you push one of them, a photon shoots out, pushes the next electron if finds, and os on and so forth.
I'm pretty sure there's actually a name for this bucket brigade type action.....
(1) wrap yourself in saran warp (2) wait for polar bear (3) polar bear kills you (4) you stay fresh for weeks until polar bear is ready to finish consuming you (5) profit
The winky (";-)") indicates it was a JOKE. Where's your sense of humour?
I still have a sense of humour and I'm in a city that's still technically in a "State of Emergency", has water problems related to the power outage, and has no reasonably priced or available gas for cars;-)
As for the transmission system, yes...needs updating....especially on the U.S. side. The sole reason that Quebec was isolated was because of the multi-billion dollar upgrades that took place after the '98 ice storm....

Maybe Windows is display that lovely map that you get in the passenger compartment on Airbus equipment ;-)

Of course. People have been doing IP over ATM since pretty much it's inception!

After all, isn't that where women originated from?

Yeah, that's like the British system......but then again, you're a Limey prison camp...so go figure! ;-)

You kinda bought that on yourself ;-) I guess maybe I did too....but I'd sure like not to pay $0.20 every time they send me an SMS!

I signed up for MSN .Net alerts....with my last phone...then I switched phone (same carrier) and tried to remove the alerts.
I've tried everything I can, and STILL get alerts on my phone (via SMS) for Hotmail and eBay, and everytime someone on Messenger tries to chat.
Do you think my carrier cares? Nope. Do you think it's easy to get ahold of anyone at MSN? Nope.
Grrrr!
