The reason why cellphone (in terms of , voice/data cell network) use is prohibited on airplanes is actually more complicated. A main reason why cell network use is prohibited in flight is that a cell phone up high in the sky will be at same distance to multiple cell towers, violating fundamental design principles of the cellphone network. The risk of using cell phone in flight is more with causing stresses on the cellphone network than interfering with an airplane's avionics. In fact, in the US, FAA (Administration of Aviation, responsible for safety of flights) did not ban use of Cell phone in fight, but FCC (Commission on Communications, responsible for regulating the cellphone network) did. |
