Airplane mode is a feature on mobile devices that disables all wireless connections such as cellular, Wi-Fi, and Bluetooth. When activated, the device is isolated from all forms of wireless communication, hence its name.

People generally use airplane mode while on a plane, which is perhaps the most application of the feature. Airlines require that devices be turned off or put in airplane mode to prevent interference with the plane’s communication and navigation systems.

Airplane mode can be activated in different ways depending on the device being used. For iPhones, users can easily toggle airplane mode on or off through a menu or by swiping up from the bottom of the screen and tapping the airplane icon. Android users have a similar menu that can be accessed by swiping down from the top of the screen.

When airplane mode is on, the device simulates being in a safe, closed environment, such as a grounded aircraft. All radio signals such as cellular signals, Wi-Fi, NFC, and Bluetooth signals are turned off or are not emitting.

Most phones come with airplane mode, but other electronic devices such as laptops, tablets, and smartwatches may have it as well. Some cars come with an airplane mode device especially for drivers who want to minimize distractions while driving.

The exact method used by a particular device to achieve airplane mode can vary, but in general, it involves disabling the devices’ RF transmitters so that they are no longer emitting wireless signals.

Most devices that support airplane mode have a physical switch that can be activated to turn the feature on and off. This is the case for many laptops and tablets, while others may require users to go into their devices’ settings to activate it.
