Airplane mode is a setting available on smartphones, tablets, and other electronic devices that disables their wireless communication capabilities. The primary reason to turn on airplane mode when flying is to comply with Federal Aviation Administration (FAA) regulations and airline policies that require electronic devices to be turned off or placed in airplane mode during certain phases of a flight. The real reason to turn on airplane mode when you fly.
During takeoff and landing, electronic devices can potentially interfere with aircraft communication and navigation systems, which can be dangerous. By turning on airplane mode, you are disabling the device’s wireless communication capabilities, including cellular data, Wi-Fi, and Bluetooth, which can prevent any potential interference.
Why then, with these global standards in place, has the aviation industry continued to ban the use of mobile phones? One of the problems lies with something you may not expect that is related to ground interference.
Wireless networks are connected by a series of towers; the networks could become overloaded if passengers flying over these ground networks are all using their phones. The number of passengers that flew in 2021 was over 2.2 billion, and that’s half of what the 2019 passenger numbers were. The wireless companies might have a point here.
When it comes to mobile networks, the biggest change in recent years is the move to a new standard. Current 5G wireless networks desirable for their higher speed data transfer have caused concern for many within the aviation industry. The real reason to turn on airplane mode when you fly.
Radio frequency bandwidth is limited, yet we are still trying to add more new devices to it. The aviation industry points out that the 5G wireless network bandwidth spectrum is remarkably close to the reserved aviation bandwidth spectrum, which may cause interference with navigation systems near airports that assist with landing the aircraft.
Additionally, turning on airplane mode can help preserve battery life, as your device will not be constantly searching for a cellular or Wi-Fi signal while in the air. It can also be a way to disconnect and avoid distractions while traveling.
