    Most broadcast antennae are not transmitting vertically. To do so would be a waste of transmitter power. So those antennae are not radiating much power into a place where they would interfere with avionics.

    It is more a case of those antennas being in a fixed location at a fixed power and known hours of operation.

    I used to fly out of Syracuse NY and would pass over the top of one of the FM broadcast stations on the way south. It was normal for me to pick up that station in the aviation radio for about twenty or thirty seconds, and ATC knew that anyone in that area was likely to be suffering from the same thing.

    It happened every time, it happened in a known place, and it was obvious what the source was. It happened long enough after takeoff that it wasn't a danger to departures, and it was not on final so it wasn't a big hazard to arrivals.

    Compare that to a situation where the radio goes kaput at a random time for an unknown cause while on final approach and you're waiting for ATC to clear you for landing and you are in the clouds trying to keep the ILS needles centered -- and it may be one of the ILS radios that is now nonfunctional. Yes, you've trained how to deal with it, but people still bend metal when instruments fail despite repeated practice going without.

    Sometimes the problem is not that you are unable to go without that instrument altogether, but that you are not easily able to determine that it is lying to you and should be ignored. If you know it will not work at a certain place, you can ignore it. If you don't know it is broken, you don't know to ignore it. I used to fly over Elmira NY and had a LORAN in the airplane. The first time I flew there, it took me a bit of time to work out why the plane I was flying suddenly had a ground speed in excess of 400 knots. After that time, I knew that I should ignore any LORAN when flying in that area -- the site of one of the LORAN transmitters. If the ground speed indication had been 50 knots instead of 400, I might not have realized what the problem was quite so easily.

    It could've been an electronics failure or a crazy pilot's error...

    That's the problem with looking at NTSB reports and trying to find "EMI caused a crash" results.

    The NTSB will test everything it can recover, and listen to the tapes. It looks at the radar tracks and interviews ground witnesses. When it finds that the electronics appear to be working, and there were no clues to any mechanical issues, the result will be "pilot error".

    The guy in seat 34B who was using his laptop or cellphone during approach will either be dead and unable to admit that fact, be oblivious to the fact that his actions may have contributed to the cause, may not even remember he left his phone ON in his carryon (and yes, I've gotten to my destination and found that my phone was on the whole time), or may be too scared of legal repercussions to admit what he was doing.

    So, sorry, I don't trust the lack of documented death from cellphone use at the wrong time as proof of anything other than a lack of documented death from cellphone use. The inability of the NTSB to make that a final determination means it won't be; it's not the fact that it can't happen.

    Or is the goal to do a botch job and get nothing and then use that as proof that every PED is safe in every airplane?

    I'm sorry, but I've been a pilot in airplanes where there has been EMI from PED so this isn't "anecdotal" evidence to me. I also know that every case of EMI doesn't result in an airplane falling from the sky because the pilots are too good at flying to allow that to happen, but it does cause extra workload usually at a time when there is already a lot. And, of course, when the worst does happen the NTSB won't necessarily be able to pin the cause on a defective laptop being used at the wrong time in the wrong place because by the time they get there the plane is a smoldering pile of metal shards and nobody will know that the laptop was being used, only that the radar showed the aircraft below the glideslope far enough that it hit the ground instead of landing on a runway. Unless the pilot is really good and really fast at diagnosing the problem and can say it loud enough that the cockpit voice recorder remembers the cause for posterity, the NTSB will chalk it up to just another case of "pilot error".

    We couldn't pin it down until one of us noticed that the signal had stopped when he answered the door. We asked "did you just turn something off?" and the rest is history. His TV was two days out of warranty, but Toshiba swapped it out anyway so they could test the thing to find out why it was emitting.
