Abstract: A method and apparatus for automatically deactivating an electronic device during flight of an aircraft. The method utilizes a global positioning system (GPS) or assisted global positioning system (AGPS) circuit to facilitate computing the acceleration, velocity and altitude of the electronic device and comparing this information to a profile to determine whether the acceleration, altitude and velocity meets a profile threshold of an airliner taking off. If the profile is that of the take-off of an aircraft, then the circuitry connected to the GPS/AGPS circuit will be deactivated.
