Airplane mode is a feature on our phones that all travelers should use when flying. Most of us know this, but have you ever wondered why it is necessary?
First, airplane mode is designed to minimize electromagnetic interference to the aircraft's communication and navigation systems. In the past, radio services were used for aviation navigation and communication, and electronic equipment could emit a signal within the same frequency, causing electromagnetic interference.
Today, the advancement of technology has eliminated this problem. Research has shown that personal electronic devices can be used without any problems during non-critical phases of flight. The European Union has allowed electronic devices to remain switched on since 2014.
So why is it still necessary to switch the mobile phone to airplane mode during flights? One of the problems is that wireless networks are connected by a series of towers, and if all the passengers flying over these ground networks use their phones, the networks can become overloaded.
The rollout of 5G networks could also interfere with navigation systems near airports that help land a plane, a very important phase of flight.
Although the use of telephones in flight does not impair the aircraft's ability to operate, many crews prefer not to delay providing in-flight service to all passengers, especially on an aircraft with over 200 passengers. Air rage can occur if too many people are talking on the phone during the flight.
