Why is it said to keep mobile off or in flight mode during flight landing and take off? || WBT3

 

People on board the plane know that whenever it is time for the flight to land and take off.The flight crew announces that the passenger should switch off his mobile phone or switch it to flight mode.The use of electronic devices on such aircraft is prohibited at such times.This is how it comes to the minds of passengers.How a small smartphone can cause problems in such a large aircraft system.

Why is flight mode done?

When passengers are asked to keep in flight mode.This means that smartphone data services such as Wi-Fi, GSM, Blue Tooth, etc. do not work. If passengers do not put their mobile phone in flight mode during landing or take-off.Signals will come out of it and they will disrupt the signals and work of the aircraft's sensitive electronic devices. 

Because even if the mobile is not in flight mode and it is simply locked and not used.It still emits signals that continue to search the network.Thus the frequency of mobiles starts interfering and disrupting the frequency of aircraft devices. 

While the aircraft is going through a difficult phase during landing and takeoff.The pilot of the aircraft in the air has to be in constant contact with the flight control center on the ground.All of this work is being done under the ship's navigation system. 

If the passenger's phone is not in flight mode.Then at such a sensitive time.The signals emanating from their mobile phones disrupt the radio communication between the crew and the center.Can't hear the information being given to it by the air traffic controller.If that happened then the plane could be in an emergency.

Which devices to use again during the flight?

A device that does not have data exchange, Wi-Fi, GSM or Bluetooth can also be used during the flight, landing or takeoff.Electronic watches (not smartphones), cameras, video cameras, video recorders, in-ear music listening devices, pacemakers, etc. can be used.

 By the way, use the mobile data exchange facility during the flight.But during landing or take off, turn them on or off in flight mode.So that the connection to the control center is maintained.The aircraft is not damaged due to signals and The lives of passengers can be saved.

Note:

 Different shipping companies have different rules.So try to follow what flight attendants announce.
