Airplane mode, aeroplane mode, flight mode, offline mode, or standalone mode is a setting available on smartphones and other portable devices. When activated, this mode suspends the device's radio-frequency (RF) signal transmission technologies (i.e., Bluetooth, telephony and Wi-Fi), effectively disabling all voice, text and phone services. GPS may or may not be disabled, because it does not involve transmitting radio waves.
The mode is so named because most airlines prohibit the use of equipment that transmit RF signals while in flight.
Typically it is not possible to make phone calls or send messages in airplane mode, but some smartphones allow calls to emergency services. Most devices allow continued use of email clients and other mobile apps to write text or email messages. Messages are stored in memory to transmit later, once airplane mode is disabled.
Wi-Fi and Bluetooth can be enabled separately while the device is in airplane mode, as allowed by the operator of the aircraft. Receiving RF signals (as by radio receivers and satellite navigation services) is not inhibited by airplane mode; however, both transmitters and receivers are needed to receive calls and messages, even when not responding to them.
Legal status in various nations
This section needs to be updated.January 2018)(
- China: Prior to September 2017, all cell phones, even with airplane mode, were 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 are in Aeroplane 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 are 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.
- United States: 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 must be disabled, while Wi-Fi may be used if the carrier offers it. Short-range transmission such as Bluetooth is permissible on aircraft that can tolerate it. 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.

Cell phones should be in airplane mode or with cellular service disabled—i.e., no signal bars displayed—and cannot be used for voice communications based on FCC regulations that prohibit any airborne calls using cell phones. If your air carrier provides Wi-Fi service during flight, you may use those services. You can also continue to use short-range Bluetooth accessories, like wireless keyboards. [...] The PED Aviation Rulemaking Committee (ARC) concluded most commercial airplanes can tolerate radio interference signals from PEDs. In a recent report, they recommended that the FAA provide airlines with new procedures to assess if their airplanes can tolerate radio interference from PEDs. Once an airline verifies the tolerance of its fleet, it can allow passengers to use handheld, lightweight electronic devices—such as tablets, e-readers, and smartphones—at all altitudes
