How often will a contact update?

• A. 6 seconds
• B. 12 seconds
• C. 30 seconds
• D. 60 seconds

Answer: (B)

The key idea is how often a contact’s position and status are refreshed on the Link 16 network. In typical practice, a contact’s track data is updated about every 12 seconds. This cadence balances keeping the track reasonably current with the need to avoid saturating the network with too many updates. If updates happened more often, the network could become crowded and slow for everyone; if they happened less often, fast-moving targets would appear stale and less reliable. While networks configured for high density can push faster updates, the standard training scenario centers on a 12-second update interval.
