What is the main function of the AFCS in relation to aircraft control?

The main function of the Automatic Flight Control System (AFCS) in relation to aircraft control is to provide basic control functions. The AFCS is designed to enhance the stability and control of the aircraft by automatically managing flight paths and attitudes. This includes maintaining a specified altitude, heading, or airspeed, allowing the aircraft to remain level and on course without constant input from the pilot.

While reducing pilot workload is certainly an important benefit and a secondary function of the AFCS, its primary role is to manage the fundamental control aspects of the aircraft's operation. By effectively automating basic control functions, the AFCS enables pilots to focus on higher-level tasks, such as navigation and strategic decision-making, rather than being preoccupied with continuous manual adjustments. This can lead to improved safety and efficiency during flight operations.

In summary, the AFCS serves to maintain effective control of the aircraft, embodying the essential functions necessary for stable flight, which is why it is correctly identified as providing basic control functions.
