uh oh ... hack the airplane ?

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?:~

Yes, but not by much.
Please remember to rate helpful or unhelpful answers, it lets us and people reading the forums know if our answers are any good.

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[^].
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p CodeProject MVP for 2010 - who'd'a thunk it!

"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.
