Which standard governs interoperability and data-sharing practices for Link 16 with partner nations?

• A. STANAG 4503.
• B. DO-178.
• C. STANAG 5514.
• D. NATO ACO.

Answer: (C)

Interoperability across partner nations depends on a shared set of rules for how data is formatted, exchanged, and secured over Link 16. STANAG 5514 provides that framework, defining the Coalition Interoperability Profile and the data-sharing practices used when NATO and partner nations connect their Link 16 systems. It specifies what information can be shared (such as tracks and status updates), how data is time-aligned, and the security measures to protect it, ensuring systems from different countries can understand and reliably use each other’s data. The other options don’t fit this role: one is a software-certification standard for avionics, another is a different Link 16 standard that covers other technical details, and the last is an organizational authority rather than a data-sharing standard.
