Which one of the following is a function of the flight management computer (FMC)?

The flight management computer (FMC) plays a crucial role in automating various aspects of flight operations, most significantly in flight planning. It helps pilots create and manage flight routes, calculate optimal altitudes, and determine waypoints along the flight path. The FMC processes data inputted by the flight crew regarding the intended route and dynamically adjusts as conditions change or as new inputs are made. This function is vital for enhancing flight efficiency, ensuring adherence to air traffic control requirements, and optimizing fuel consumption during the flight.

While other systems on the aircraft may handle aspects like weather tracking, fuel management, and engine monitoring, these tasks are not within the primary scope of the FMC’s responsibilities. Weather tracking is typically managed by onboard radar systems and displays, while fuel management is often monitored through separate fuel data systems. Engine monitoring is managed by the engine control system, ensuring that the aircraft’s engines operate within safe parameters. The FMC is primarily focused on navigation and route management, making flight planning its core function.
