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.

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.

Have you never seen Die Hard 2? The could change what ground level was!
Some men are born mediocre, some men achieve mediocrity, and some men have mediocrity thrust upon them.

That's actually exactly what I was thinking of when I mentioned the navigation equipment 
|

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.
Still, better than being blown up isn't it?

Ever land in Denver. I think many "unhacked" aircraft think Denver's runways are about 10 ft below their actual elevation.

Sorry, that just reminded me of this

I was waiting for one of you to spot that.
Well done that man.

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[^].

-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.

The batteries are only used while other power sources (engines, APU) are off-line. In normal operation, they don't provide power, just (as you say) consume it to be recharged.
Although that would all change if this beastie[^] were to be made...

Interesting; essentially a turbo shaft powering propulsors. No apparent need for a bypass-type  engine unless the propulsors are supplementary.
Redundancy again.
Loss of the power bus would enable the fan to keep the craft aloft until a diversion could be found.

This sounds a lot like what this guy demonstrated a year ago[^]. So the news here probably isn't that its possible, but that someone else has done it.
We can program with only 1's, but if all you've got are zeros, you've got nothing.

Started installing the system and software on my new system. Right now on 100 of 147 Windows 7 updates so in limbo for a while.
Installing Wine on the SSD, had to do it twice guess the first time got corrupted or ?? But 2nd time installed just like it oughter.
Got a Windows experience index of 6.9 but it's because I have an old video card else it would have been 7.7
The dang thing runs like a scalded dog...I love it!
Have you ever just looked at someone and knew the wheel was turning but the hamster was dead?
Trying to understand the behavior of some people is like trying to smell the color 9.
