The Flight Management System (FMS) utilizes multiple sensor inputs for navigation, making it the correct answer. This system integrates various data sources to provide comprehensive navigational assistance to pilots.

An FMS typically processes information from Global Positioning System (GPS) satellites, inertial reference systems, VHF omnidirectional ranges (VOR), and distance measuring equipment (DME), among others. By combining these inputs, the FMS can calculate the aircraft's position, velocity, and trajectory more accurately than relying on a single data source.

This multifaceted approach enables the system to update its navigation calculations dynamically, improve situational awareness, and enhance flight planning and execution, thereby optimizing flight routes and reducing workload for pilots. The reliance on multiple data sources ensures redundancy and accuracy, crucial for safe and efficient air travel.
