How often are LPAs transmitted?

How often are LPAs transmitted?

• A. Every 60 seconds
• B. Every 5 minutes
• C. Every 10 seconds
• D. Every 96 seconds

Answer: (D)

In Link 16, many data items follow fixed transmission cadences to balance timely information with network bandwidth. LPAs are a specific type of message that gets sent on a regular schedule to provide ongoing status or authorization-related information without clogging the channel. The transmit interval for LPAs is every 96 seconds. This cadence keeps information reasonably current while avoiding excessive traffic, which could interfere with higher-priority data and other network activities. If it were transmitted more often (like every 60 seconds or every 10 seconds), you’d risk saturating the network with this type of message. If it were much less frequent (like every 5 minutes), the information could become stale for operational needs. So, the 96-second interval is the standard balance for LPAs in typical Link 16 practice.
