Before taking off and landing, customers will be required to power off their phone to ensure the safety.
WHAT MAY HAPPEN IF YOU DON’T SHUTDOWN YOUR PHONE ON THE AIRCRAFT
It is becoming familiar with every airline companies over the world when requiring passengers to turn off their devices especially laptop or mobile phone. Even if you establish your devices in air plane mode before taking off and landing, this is still discouraged. Although the strict principle is undeniable, but there are not many people understanding why airline companies require that and what will happen if the rule are not obedient?
According to statistic data, taking off and landing time is by far the most susceptible during flight journey, maybe the cause for several flying accidents. This may last from 15 to 20 mins to reach the requiring height of takeoff and landing, which demands the strong focus of pilots and the frequently signal exchange with air traffic control. Besides, devices equipped on the plane need to be highly accurate.
Many experts show that electronic devices and cellphones can emit the radio waves which possibly interfere the system of aircraft. Even if your phone is put in air plane mode, it still emits a certain amount of radio waves while this wave is the main mean to transfer information in avionic system.
If you don’t power off your phone, you may help this radio waves interrupt the communication between airplane and ground, which possibly distract and create difficulties for pilot during the important period. The mobile waves can interfere the electronic system of the aircraft. Most of this system uses radio signals to send and receive information, so it is very susceptible to be interrupted by devices having the same radio frequency.
Although there are not any accidents caused by the radio waves, but this can make the control and operation face to several obstacles. Thus, almost all airline companies require their passengers power off their mobile phone until the plane reaches the stable height and the signal lights turn off, then they possibly restart their phone. However, the phone should be set up in air plane mode instead of normal mode.
