Every time we fly, the air hostesses make sure that the phones of each passenger is either switched off or in airplane mode.
There will also be a safety announcement before taking off, which reminds us of the same again. There are legit reasons for this and if you don’t comply there could be consequences. In this article we go through the reasons for this precaution.
There is no proof yet that there is any correlation between forgetting to put phones on airplane mode and plane crash. This assumption is completely invalid. So we must know the real reason of this precaution.
When we fly above 10000 feet at lighting pace your phone will try to connect to the local towers by sending signals. However, as your phone picks up weak signal from the corresponding tower it will try to send stronger signals to establish the link.
As a result network connection on the ground could get jammed. Your phone will try to connect with various towers at the same time which results in network congestion.
Another important reason is that keeping the phones switched on can create a noise that can interfere with the communications of the pilot.
Strong radio emissions up to 8W can create huge noise in the headset of the pilot while he is getting critical information from ground control. It could turn out to be disaster.
So the staff of the air services ask you to switch to airplane mode because it prevents massive radio pollution. It is a common courtesy which shows that you really appreciate the job they are doing. You don’t want to annoy the pilot who is in charge of taking you to your destination.
