What is one of the main benefits of utilizing a Flight Management Computer (FMC)?

Utilizing a Flight Management Computer (FMC) significantly reduces pilot workload during flight operations, which is one of its primary benefits. By automating various tasks related to navigation, flight planning, and performance management, the FMC allows pilots to focus on other critical aspects of flying. It manages tasks such as trajectory computations, waypoint sequencing, and route adjustments, which previously required substantial manual input and constant attention from pilots.

This automation is particularly beneficial during phases of flight that demand high levels of attention and management, such as takeoff and landing, as it helps to streamline decision-making and increase situational awareness. Consequently, this reduction in workload not only enhances safety but also improves overall operational efficiency.

While improving fuel efficiency can be a consequence of the optimal flight paths calculated by the FMC, the primary design purpose is to alleviate the cognitive and operational burden on the flight crew. In contrast, increasing maximum cruise altitude or facilitating emergency procedures are not direct functions of the FMC; instead, they pertain to different aspects of aircraft design and operational protocols.
