Most of us may feel it is unnecessary to switch to airplane mode during flight.
So, what is the truth?
There is no evidence that signals from passengers electronic devices have ever caused a plane to malfunction and crash.
This is something that might congest the networks on the ground.
But, there has never been a case of a cell phone causing a plane to crash.
He said: Your phone will probably annoy a few pilots and air traffic controllers.
I actually heard such noise on the radio while flying.
It is not safety critical, but is annoying for sure.
Planes with onboard cell coverage, allow your phone to communicate using very low power, or Wi-Fi.
So, when you are flying next time, it is advisable to stick to the rules onboard.
