When enabled, the feature disables mobile data, Wi-Fi, Bluetooth, NFC, and GPS on the cellphone to prevent interference with aircraft systems. However, it is still possible to use two of these features during the flight; let’s understand why. Airplane mode on cellphones: why it is necessary to activate this feature during flights
The latest cellphones are equipped with connections that use electromagnetic waves, also known as “radio waves,” to exchange information, and these technologies can interfere with the equipment of certain aircraft. That’s why smartphones need to be switched to “airplane mode” during takeoff and landing.
Airplane mode is a setting available on most modern cellphones that allows users to quickly disable multiple wireless functions simultaneously. When activated, it turns off the device’s cellular network, Wi-Fi, Bluetooth, near field communication (NFC), and Global Positioning System (GPS).
During critical phases of a flight, such as takeoff and landing, it is crucial to minimize any potential radio frequency (RF) interference that could affect the aircraft’s navigation and communication systems. The RF signals emitted by cellphones have the potential to disrupt the sensitive electronic equipment aboard an airplane. By activating airplane mode, passengers help ensure a safer and more reliable flight experience.
In airplane mode, the cellphone effectively becomes a self-contained device, isolated from external networks. This prevents the phone from transmitting or receiving signals that could interfere with the plane’s avionics. While in this mode, functionalities like making phone calls, sending text messages, and browsing the internet using mobile data are disabled.
However, there are exceptions to the complete shutdown of all wireless functions. Aviation authorities permit the use of specific features even when the cellphone is in airplane mode. These exceptions typically include the use of Wi-Fi and Bluetooth when provided as in-flight entertainment options or when allowed by the airline. Passengers may connect to the aircraft’s Wi-Fi network to access internet services, watch movies, or listen to music. Some airlines also enable Bluetooth connectivity for wireless headphones or other approved devices.
It’s important to note that these exceptions may vary depending on the airline and aircraft model, so it is advisable to comply with the specific instructions provided by the airline crew or consult the in-flight information available.
In conclusion, activating airplane mode on cellphones during flights helps prevent potential interference with the aircraft’s systems caused by electromagnetic waves emitted by these devices. While in airplane mode, most wireless functions are disabled, but some exceptions, such as Wi-Fi and Bluetooth, may be allowed under certain circumstances. By following the guidelines provided by the airline, passengers can ensure a smoother and safer journey while still enjoying limited connectivity options during their flight.
