Which system connects to VIDS to show FDIO information?

The system that connects to VIDS to show FDIO (Flight Data Input/Output) information is the PC-RCU (Portable Computer - Remote Control Unit). This unit is designed for specific functionalities including interfacing with various data systems and allowing users to access real-time flight data. By connecting with VIDS (Visual Information Display System), it can display relevant FDIO information for avionics or operational purposes, enhancing operational efficiency and situational awareness for flight crews and operational personnel.

Other systems listed do not serve this specific function. For instance, ETHAN and ETVS have different focuses, such as operational management and vehicle tracking systems, while AVAIL is more related to resource availability and scheduling rather than direct FDIO data connection. Thus, the PC-RCU stands out as the necessary link for retrieving and displaying FDIO information through VIDS. This capability is essential for maintaining accurate and timely information flow in aviation operations.
