Enabling and disabling wireless communication in electronic devices

A device comprising:

• an inertial measurement unit (IMU) configured to independently indicate whether an aircraft on which the device is aboard is in flight or stationary;
• a pressure sensor configured to independently indicate whether the aircraft on which the device is aboard is in flight or stationary;
• and
• a controller coupled to the IMU and the pressure sensor two or more sensors and configured to:
• receive, from the IMU and the pressure sensor, a first indication that the aircraft is in flight;
• receive, from the IMU and the pressure sensor, a second indication that the aircraft is stationary;
• and
• in response to the second indication:
• receive acceleration data from the IMU, wherein the acceleration data is indicative of an acceleration of the device in at least one dimension relative to an orientation of the device;
• and
• transform the acceleration data from being indicative of the acceleration of the device in the at least one dimension relative to the orientation of the device to being indicative of the acceleration of the device in the at least one dimension relative to a direction of gravity.
