If airplanes were vulnerable to radio frequencies, then terrorists have no need to acquire SAMs. A nice powerful amateur radio should do much better.

  Avionics systems are better shielded against external interference than they are against internal interference.

    Based on how Faraday cages work, I don't see how that's possible. Do you have a technical explanation or did you just pull that out of thin air?

      Planes (well, most of them at least) have metal skins. The avionics -- and the passengers -- are inside this skin.

        Well, you can easily see that the plane's skin is not a Faraday cage since you can make cell phone calls, use your GPS etc.

          It doesn't provide complete shielding, no. But it does provide some shielding.
