How to Turn on Airplane Mode on an iPhone or Android Device ...

Airplane mode, aeroplane mode, flight mode, offline mode, or standalone mode is a setting available on many smartphones, portable computers, and other electronic devices that, when activated, suspends radio-frequency signal transmission by the device, thereby disabling Bluetooth, telephony, and Wi-Fi. GPS may or may not be disabled, because it does not involve transmitting radio waves.

The name comes from the prohibition by many airlines of using equipment transmitting radio-frequency signal while in flight; using airplane mode prevents devices from transmitting.

When the "airplane mode" is activated, it disables all voice, text, telephone, and other signal-transmitting technologies such as Wi-Fi and Bluetooth. Wi-Fi and Bluetooth can be enabled separately even while the device is in airplane mode; this is acceptable on some aircraft. Receiving radio-frequency signals, as by radio receivers and satellite navigation services, is not inhibited. However, even receiving telephone calls and messages without responding would require the phone to transmit; a smartphone in airplane mode is effectively a PDA.

In a revised review in October 2013, the United States Federal Aviation Administration (FAA) made a recommendation on the use of electronic devices in "airplane mode"--cellular telephony is disabled, while Wi-Fi may be used if the carrier offers it. Short-range transmission such as Bluetooth is always permissible. The statement cites the common practice of aircraft operators whose aircraft can tolerate use of these personal electronic devices, but use may still be prohibited on some models of aircraft.

While in airplane mode, most devices allow the user to continue to use their email client or other program to write text or E-mail messages which are saved in memory to send when airplane mode is disabled.

Although it is not possible to make normal calls or send text in airplane mode, devices such as some Nokia smartphones allow the user to make calls to emergency services even in airplane mode, while others do not.

As a side-effect, airplane mode reduces power consumption and increases battery endurance by shutting down the device's transmitters and receivers.

Legal status in various nations

  • China: Prior to September 2017, all cell phones, even with Airplane mode, was never allowed to be used during the flight although other devices can be used while in cruising altitude. On September 18, 2017, the Civil Aviation Authority of China relaxed these rules and allowed all Chinese air carriers to allow the use of Portable Electronic Devices (PEDs) for the entire flight as long as they're in Airplane Mode.
  • Europe: On December 9, 2013, the European Aviation Safety Agency updated its guidelines on portable electronic devices (PEDs), allowing them to be used throughout the whole flight as long as they're set in Airplane mode.
  • India: On 23 April 2014, the Directorate General of Civil Aviation (DGCA) amended the rule which bans use of portable electronic devices and allowing their usage in all phases of flight.
