What is the procedure to follow if transponders do not respond during defense operations?

In the context of defense operations, if transponders do not respond, notifying the ADCF (Air Defense Control Facility) is crucial. The ADCF acts as a central command and communication hub that oversees air defense measures. When transponders fail to respond, it is essential to inform the ADCF to assess the situation appropriately. They can analyze the data and coordinate the necessary responses, which could include advising on potential identification and engagement of unknown aircraft.

Communicating this failure ensures that the command structure is aware and can adjust strategies or take necessary safety precautions, maintaining an effective response to any aerial threats. Keeping the ADCF in the loop helps prevent misunderstandings and ensures proper protocol is followed in defense operations, where situational awareness is critical.
