What J-series message is for an air track?

• A. J3.0
• B. J3.1
• C. J3.2
• D. J3.3

Answer: (C)

In Link 16, track information is carried in J-series messages, and the subtypes define what kind of track data is being transmitted. For airborne targets, the specific J-series subtype used to convey the air track data is J3.2. This subtype is designed to carry the track state for aircraft—such as position, velocity, altitude, and status—in a standardized format that all participants can interpret consistently. That is why J3.2 is the best choice for an air track. The other J3 subtypes are used for different contexts or varieties of track data, so they aren’t the air track message.
