Abstract
A wireless transmitter device that has a baseline ‘off’ status, turning its data transmission module ‘on’ only under certain specific circumstances, thus allowing the device to be used on aircraft without concern of the device activating and transmitting location data that might interfere with the aircraft navigation and/or communication systems. The data transmission module may be turned on manually, may be activated based on time, or may be activated based on motion. Activation of the data transmission module occurs only after it has been determined that it is safe to activate the module(s), for example, if no motion of the device has been sensed for a predetermined period of time. Only after the device has assuredly determined that the aircraft is in a mode where data transmission is allowed (e.g., not in flight) is the data transmission module activated.
