Which statement about LRLY is true?

• A. LRLY enables relay mode; enabling will allow another platform to command the helos Link 16 MIDS into relay mode without crew notification
• B. LRLY has no effect on relay operations
• C. LRLY automatically enables relay mode when link quality is high
• D. LRLY disables relay functionality

Answer: (A)

LRLY is the relay-enable control for a Link 16 MIDS node. When this flag is set, the aircraft’s MIDS can operate in relay mode and, crucially, can be commanded by another platform in the network to enter relay mode without the crew having to manually switch it. This matches how relay capability is used to extend network reach in a Link 16 environment, by allowing remote control of relay functionality to support broader data distribution. It isn’t something that happens automatically just because link quality is high, and it isn’t correct to say LRLY has no effect or that it disables relay—LRLY’s purpose is specifically to enable and permit remote relay operation.
