When must arrival information be forwarded to GWO TWR if FDIO is non-operational?

Forwarding arrival information to GWO Tower before the aircraft reaches the D surface area is crucial for maintaining effective communication and ensuring the safety of aircraft operations in the airspace. This requirement is in place to provide the tower with necessary situational awareness about incoming aircraft, allowing them to prepare for landing and manage the traffic effectively, especially when FDIO (Flight Data Interface Operations) is not operational.

By sending this information prior to reaching the D surface area, the tower controller can integrate the data into their workflow, ensuring that they are fully informed about the aircraft's status, including its intentions and any unique circumstances that could affect its landing. This proactive communication helps to mitigate any potential conflicts or mismanagement of air traffic during critical phases of flight, thereby enhancing overall safety and efficiency in the airspace.
