Flight mode
From Wikipedia, the free encyclopedia
Flight mode (or airplane mode) is a feature included in some electronic devices that deactivates radio transmitters and receivers. It mostly applies to cell phones, but it is applicable to any electronic device that transmits radio signals as its primary function. In this mode the phone's secondary features (such as its music, games, or scheduler) can be used safely in environments requiring minimal radio interference, such as planes and clinics.
The term is something of a misnomer, as many airlines continue to prohibit all use of cell phones on aircraft, with some specifically announcing onboard that even cell phones with a flight-safe mode may not be used inflight.[citation needed] As a practical matter most cell phone users simply treat flight mode as a power-saving feature or a soft-off.
The Sony Ericsson P800 mobile phone was one of the first to introduce this feature[1], though it is now a common feature of many phones.
