Of course, anything electrical can automatically be switched to run off battery power, if cut off. I'm sure these devices can be modified so they can never be killed.

Where there is a will there is a way. EMP would be one way.

No doubt. I know next to nothing about this stuff.

So, put it in a Faraday cage.

So you open the cage first then set off the EMP.

When I was in the Air Force all electrical devices had to be shut off before we could commence refuelling. I found this on the internet.

"Basically everything that consumes power on a aircraft can potentially cause interference, short-circuts, or otherwise jeopardize the safety of flight and therefore must be switchable. Sometimes the switch is in the form a button, otherwise by a fuse.

There are several particular reasons that the transponder can be turned off.

If the transponder malfunctions, it may cause interruptions to all ATC surveillance in an area. There have been instances in the past that due to a fault in the transponder it was basically acting as a jammer.

In one particular incident it took a while before the aircraft that caused it was identified and after requesting the pilot to switch of the transponder, secondary surveillance was restored.

Another reason is that when the aircraft is at the gate, the transponder is switched of to reduce the amount of radio transmissions. 100 aircraft on the surface of a large airport can produce a massive Radio Frequency noise, which negatively affect radar systems. When taxiing, radar replies are useful for aircraft identification, hence the transponder is switched on at pushback or engine start."

I had to look up Faraday Cage. So THAT'S what that mesh is in my microwave oven! Now I've learned something new---- at least it's name, not how it works! That's over my head.

I just love discussions like this---- dribs and drabs keep dribbling through.

Do you think that what was written in Aviation Week could be connected to plane crash? (I know nothing about this kind of 'stuff' so my question may be totally off topic.)

Your car is a Faraday cage. So if you are inside your car, even if it got hit by lightening, provided you aren't touching the metal of the car, you won't be electrocuted by the lightening.

I don't believe so. I read the article you posted and yes it's maybe plausible, but I would think Boeing is smarter than to have their entertainment system interlinked with the nav system. However, one thing that has always made me think is, on all the flights we take every year, we have access to the GPS tracking on the consoles (or the tv's) of the planes position. It has always made me a bit uncomfortable. Maybe it's my prior career in the Air Force.
