Mobile phones on plane many question?

Hello. In my last flights a while ago the Flight Woman told me to remove my mobile phone from service because of take off and landing only. I ask her why but she did not tell back to me.What is it? Do my mobile phone insult the functionality of the plane during take off and landing? Can it harm the navigation of the captain? Or does it harass the electricity of the plane? Is the captain allowed to turn on his mobile phone during take off?And in flight I was scaring because there was a thunderstorm outside from the plane. I turn my mobile phone of really fast. Can the thunderstorm call my mobile phone during flight and kill me?And there was another guy who was in use of his mobile phone during landing. He was sitting away and I was talking to him really loud to turn of his mobile please. The flight woman tell me to be shut down my service of talking. She was not tell him to take it out of service! Why are other people allowed to use their during landing?

Answer:

Pretty simple. It has nothing to do with the electronics in the plane. When you are taxing to the runway, the flight crew goes over the flight safety information. Takeoffs and landings are the most likely time that there may be difficulties. In all cases it's so you pay attention to the crew, not be fussing around with your phones or other electronics.
Restrictions on the use of mobile phones are a legal matter, not a safety matter. Despite what some flight crews say (and what airlines deliberately teach them), mobile phones do not interfere with aircraft systems. In the United States, FCC regulations prohibit the use of cellular telephones at any point in flight (flight being defined as any time that the aircraft's wheels are not touching the ground). This means the whole flight, not just takeoff and landing. The restriction was put in place because the FCC feared that cell phones in the air would overload base stations on the ground. This turned out not to be a problem, but the restriction is still in place. The relevant regulation is 47 CFR § 22.925. The FAA also places restrictions on the use of portable electronic devices in flight. This restriction arose out of the fear that electronic devices would interfere with aircraft systems. This also turned out not to be a problem, but the regulation is still in place. The relevant regulation is 14 CFR § 121.306 for airlines. So the only reasons for the restrictions are legal restrictions. It's not a matter of electronic interference, or the crew getting yoru attention, or anything like that. Anyway, airlines vary in their zeal for enforcement. The FAA itself encourages airlines to ignore its regulations during certain phases of flight. See Advisory Circular 91.21-1B.
Honestly, having a cell phone on in flight probably won't do anything to the plane itself. but, once an airplane is in flight, the phone can't get the signal because the plane is moving too fast to lock on to the signal. Not only does it kill your battery because it takes a lot more energy for your phone to try and lock onto a signal, it's against the law to operate your phone so just turn it off. You can once your above 10,000 feet however, use your phone in 'airplane' mode which means the phone is not sending, receiving or trying to lock onto a signal.
I couldn't realise why someone would object to cell calls on planes - until I used to be on a bus within the rush hour with a woman utilizing up her 600 free minutes. I and the rest of the bus had over an hour of inane drivel. I began walking alternatively.
