Which of the following are basic components of a flight management system (FMS)?

The correct choice identifies fundamental components of a flight management system (FMS), which is integral to modern aviation. Within an FMS, the navigation database, performance database, and flight plan management work collectively to enhance the accuracy, efficiency, and safety of flight operations.

The navigation database provides critical information about waypoints, airways, and navigation aids, which is essential for route planning and execution. The performance database contains data regarding aircraft performance metrics under various conditions, which helps in optimizing flight paths considering factors like weight, weather, and altitude. Flight plan management involves the ability to create, modify, and execute flight plans systematically, ensuring that pilots have real-time access to necessary information for safe flight operations.

Together, these components of an FMS facilitate advanced automation of navigation and performance calculations, leading to improved operational efficiency and safety throughout the flight process. Other choices reference systems that, while essential for overall flight operations, do not fall within the defined scope of basic FMS components.
