WiFi interfering with TCAS... sounds scary enough to me.....
Intruder,
It would not just need a crash; it would need a crash
proven to have been caused by EMI from "something" in the cabin.
Try and extract
that sort of information from a smoldering wreck?
I tend to scoff at all the "principle of precaution" waffle these days.
But in this case, I'm all for it.
soddim,
There are also possible issues with fly-by-wire control systems.
Most if not all of that
does pass through shielded wiring. The main problem is with aircraft systems that emit and receive RF signals on frequencies similar to that emitted by the typical electronic devices that we carry around with us, such as cellphones, video games, laptops with WiFi, etc.
