What additional equipment is present alongside FDIO servers?

The presence of two printers alongside FDIO (Flight Data Input Output) servers is essential for operational efficiency and data management. These printers are typically used to generate hard copies of flight data reports, operational logs, and other critical information that may be necessary for air traffic control personnel and other stakeholders. Having dual printers ensures redundancy, meaning if one printer fails, the second can still provide the necessary documentation. This is crucial in aviation environments where maintaining accurate records is a regulatory requirement and important for safety.

The other options, while they may be relevant to aviation and air traffic control, do not necessarily accompany FDIO servers directly. For example, radar displays are used for monitoring aircraft positions but are part of a different system. Various scanners can be useful for scanning documentation or personnel but are not standard equipment directly associated with FDIO servers. Flight simulators provide training but are not connected to the operational functions of FDIO servers. Therefore, the presence of two printers is the most pertinent equipment that supports the functioning of FDIO servers in the operational context.
