Final answer:
The L AFCS and R AFCS switches are used to activate or deactivate the left and right automatic pilot systems, respectively, in an aircraft. They are crucial for managing the autopilot functions which reduce the workload on pilots.
Step-by-step explanation:
The L AFCS and R AFCS switches are part of an aircraft's autopilot system, also known as the Automatic Flight Control System. These switches are typically used to activate or deactivate the left and right sides of the AFCS, respectively. When you toggle these switches, you are essentially turning on or off the autopilot function for each side of the aircraft, allowing the system to control flight parameters such as altitude, speed, and direction. This is crucial for reducing the workload on pilots, especially during long flights or complex maneuvers. The AFCS works by using a series of sensors, computers, and flight control systems to maintain or change the aircraft’s flight path according to the pilot’s inputs.
