What is the correct sequence for a data update from a sensor to other participants in a Link 16 network?

• A. Sensor data source → Terminal input → Link 16 data message → Distribution to net
• B. Sensor data source → Link 16 data message → Terminal input → Distribution to net
• C. Terminal input → Sensor data source → Link 16 data message → Distribution to net
• D. Sensor data source → Terminal input → Distribution to net → Link 16 data message

Answer: (A)

Data moves from its source to the network in a logical data-path: sensors produce the measurements, the terminal ingests that data (terminal input) and prepares it for transmission, the terminal formats it into a Link 16 data message, and then that message is distributed to all participants on the net. This order ensures the information is actually created and properly encapsulated before any transmission occurs. If you tried to distribute before the data message exists, or tried to input data after attempting to send, the data would be incomplete or invalid for the Link 16 protocol.
