yeah—that does not convince me as i have read other info on other sites that say it is not unsafe... again, if it were, cell phones would not be allowed... the same way bombs are not allowed...
Among every person I have read or heard claim it is not unsafe, not one of them is qualified to make that assessment.
The IEEE article that was provided to you is an authoritative source, written by people that have forgotten more about EMI (electromagnetic interference) than most people have ever learned. You shouldn't discount it so easily, unless you have similar credentials.
EMI from cell phones (and other transmitters) by itself isn't the problem. It's what happens after EMI occurs. Pilots are trained to recognize and compensate for avionics interference. We also have procedures for complete radio failure, and air traffic control knows what to expect if we use them.
Aviation safety is the result of layers: we have backups, and backups for backups. But, whenever you remove a layer, the margin of safety is reduced. And you run the real risk that interference distracts pilots from another problem that poses a real danger to the plane.
