Just wanted to share some technology Information to Architects & developers, while I still protect the IP rights for the same.
I was too lazy to write article on it, and this post is only for those who might be interested in the same.
Others don't mind - I really wont be making any money out of this posting and ofcourse I am targeting the Lounge visitors.
Maybe attach a creative commons license[^] to the post? At the very least it will show your intentions, and (IANAL) provide prior art of the idea. At least assuming an admin doesn't delete your post and run to the copyright office.
"Cyber security researcher Ruben Santamarta says he has figured out how to hack the satellite communications equipment on passenger jets through their WiFi and inflight entertainment systems - a claim that, if confirmed, could prompt a review of aircraft security." [^]

Satellite comms? Wow. Fundamental. Not.
My first flight as a twelve year old was on a Boeing 720 to Canada. We didn't have no stinking satellite. When the crew invited me onto the fight deck, they showed me frost on the side window from the -50 degree air, and how the navigator used the stars through a viewing dome in the roof.
Flight controls have come a long way since then; they are 'By Wire', so electric, but they won't be connected to any other system except the batteries and their own, dedicated, presumably hard-embedded computing. The batteries which take on the role of old hydraulic accumulators.
On the other hand....are we talking about modern engineers?
Agreed, I doubt that the in flight entertainment system would be connected to the throttle and steering yoke. If it was the navigation equipment that he'd hacked into then I could see the potential problem but other than singing "this is the song that will get on your nerves" over the comms there isn't a right lot anybody can do with this.
That's the worst that could happen.. There you are sipping your drink while watching "Die Hard 2" on your in-flight screen when all of a sudden, everyone's film gets changed to "Love Actually" on repeat, for the full duration of the flight.

Mmmmm - possibly not... The yoke & throttles are just the user interface, really - the flight control system has overall control of an airliner's attitude, altitude and speed, so needs to be able to command the control surfaces, the engines...all of the aircraft systems, really. Airliners these days have (slightly modified) ethernet connecting all these mission-critical systems, in order that they can communicate. That network is separated from the cabin network systems, although I'm not sure if the separation is via an air-gap or by using appropriately filtering switches - you'd hope an air-gap...
Oh - and they don't tend to use batteries either - power comes from the engines or (if they're not running) an APU[^].
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p
"Oh - and they don't tend to use batteries either - power comes from the engines or (if they're not running) an APU[^]."
-Er yes. The engines probably feed the battery. Remember when 787's were grounded? Although direct power(through a regulator) would be more in keeping with redundancy of systems, and is thus far more desirable. I believe the first FBW plane was the Avro Vulcan of the 1950's. They even had to develop new lubricants for the control surfaces as they were flying around 60,000 feet.
Interesting; essentially a turbo shaft powering propulsors. No apparent need for a bypass-type engine unless the propulsors are supplementary.
Loss of the power bus would enable the fan to keep the craft aloft until a diversion could be found.
Although I used to love this show, this is totally insane! I really hate greed, and this almost makes me want NOT to watch the show, ever!! :unwell:
Also if I remember it right, they had to do the pilot episode again due to the so called "characters' emotions" were not proper during the first shoot. Aslo Kaley couldn't even get Penny's role out of her first audition.
Granted they have improved a lot since then, but it's still insane given that there are a lot many other fields like firefighers, cops, soldiers, teachers who do not get that much pile of money but they still do their jobs which are undoubtedly much more needed to the country..
Whether I think I can, or think I can't, I am always bloody right!

I understand where you are coming from, but this point of view is rather naïve. I've learned that in modern society, you get paid based upon how easily you are replaced, not based upon how valuable your service is. Firefighters and cops perform necessary services, but individually they are easy to replace. The actors on that show are NOT easy to replace because theirs is a rare skill.
The difficult we do right away...
...the impossible takes slightly longer.
