The FAA just makes me laugh. I still cannot understand why the reasoning for having all electronics off under 10,000 ft. is because of potential interference. At this point, that reason is nothing but bogus and it is clear the average flier feels the same way. Studies have been done to see what kind of electronics are on during takeoff and landing and the amount of electronics emitting a signal (some because people just don't obey the rule and some because people forget that the device in their carry-on is still in the on position) is quite high.
If the FAA really wants to be taken seriously on this rule, it should flat out say that electronics need to be off because, should an emergency occur, the crew would need your undivided attention. Not to mention, it is best for the passengers to be fully aware of their surroundings to have some sort of preparation in an emergency, rather than having no idea what is going on thanks to, let's say, noise-cancelling headphones.
Good points, except I'm not so sure the actual reason for the ban is for interference reasons. The FCC banned cell phones from aircraft a long time ago when there was a theory that airborne cell phone usage could jam cell tower networks. Now that this risk has been eliminated through modern cell phone network technology, I
thought the ban was still there to prevent what you described in your second paragraph.
I'd like to see the language of the actual regulation that prohibits electronics usage below 10,000 feet, and whether or not it actually mentions the prevention of interference. Otherwise, it's something the airlines can change in their passenger announcement scripts.
