What must be included in the arrival information forwarded to GWO TWR when FDIO is non-operational?

The correct choice focuses on essential information required for the efficient and safe management of arriving aircraft when the Flight Data Input/Output (FDIO) system is non-operational. In such scenarios, it is crucial for the Tower (TWR) to receive detailed approach information, which includes the type of approach being conducted as well as any relevant clearance details. This information assists the tower personnel in preparing for the aircraft's arrival, ensuring that they can provide the necessary instructions and maintain safety protocols during the landing phase.

Other options, while relevant in different contexts, do not provide the same level of operational detail needed in this critical situation. For instance, while flight number and fuel status are important, they do not convey how the aircraft intends to land in a non-radar environment. Similarly, total crew information and emergency contact details might be useful for operational purposes but are not as immediately pertinent to the arrival sequence compared to approach and clearance information.
