If you think that there is formal rule about switching off cell phones during the flight takeoff, then you should read this in detail.
Do you remember that how many times you had to curtly hang up on someone or send a quick text message before your flight taking off? It is because all of us ultimately give up to the continuous nagging of the flight attendants during every flight.
During booking flights, most of us feel bad about this thing that we will have to switch off our mobiles while traveling. However, if you think switching off mobile phones on a flight is mandatory, here is complete information for you. The Federal Aviation Administration (FAA) does not officially prohibit from using personal electronic devices during flights.
So, the question is why we are asked to switch off the phones?
And the answer is very simple, because almost each electronic device, including mobile phones, emits radio waves. Supposedly, if frequency of these radio waves is parallel to that of the navigational tools, it may disturb the aeronautical equipment in the cockpit. Apart from this, while flying at a high altitude, cell phones emit stronger signals, hence resulting into network congestion on the ground. Though, these signals have never caused any plane crash till today rather many airlines have now also introduced in-flight Wi-Fi services.
This rule has been made only as a precautionary measure and most of the airlines make sure to get the electronic devices switched off primarily due to precaution during takeoff or landing. These periods are supposed to be most critical phases for a flight. So, it’s better to switch off the phones instead of feeling sorry about any incidence.
