Which of the following best describes a benefit of using an FMS during flight?

Using a Flight Management System (FMS) during flight significantly facilitates streamlined flight operations. The FMS automates various navigational tasks, allowing pilots to focus on other critical aspects of flight management, such as monitoring systems and communicating with air traffic control. It enhances efficiency by providing optimal flight paths, managing fuel usage, and integrating data from various navigational sources, which ultimately leads to a smoother operational process.

While it might seem that an FMS could increase workload or reduce navigational accuracy, its primary function is to actually lessen pilot workload through automation and enhance navigational precision by providing accurate route management. Furthermore, while the FMS can assist in some navigation tasks, it does not entirely eliminate the need for flight charts, as pilots still need to reference these for various procedures and contingencies. Therefore, the statement about facilitating streamlined flight operations captures the primary advantage of employing an FMS in modern aviation.
