The FCC has determined that cell phone use on airplanes is safe and with the proper equipment does not interfere with ground cell networks. The FCC is ready to lift a ban they put in place in 1991.
Yet other agencies and members of congress are ready to jump to see that the ban stays in place. The reason is not the integrity of communications networks or flight safety, but because of passenger preference.
Do really need laws and regulations in place because of consumer preference? Shouldn’t that be left to the airlines to decide if they want to permit their customers use cell phones on their planes or not? If an airline wished to cater to people that want to use cell phones while flying, they could offer it, if they wanted to preserve to quietness of the cabin they could ban it on their flights.
