What happens if an attempted handoff of FDB to another facility fails?

When a handoff of Flight Data Block (FDB) to another facility fails, the procedure involves aborting the handoff attempt. This is crucial because the FDB contains important real-time data about the flight, including altitude, speed, and other operational information that is essential for the safe and efficient management of airspace. If the handoff cannot be completed successfully, it is necessary to ensure that the current controller retains control and oversight of the aircraft.

Aborting the handoff prevents potential confusion or loss of information that might arise if the data were to be partially transferred or if there were uncertainty about the aircraft's position and status. This allows the originating facility to maintain communication and ensure that all necessary data is accurately reflected in their system until a successful handoff can be achieved or until further action is required.

Successful handoffs typically require coordination and confirmation between facilities, and any interruptions in this process necessitate retraining of responsibilities to avoid jeopardizing safety.
