Basic autopilot functions are provided by which of the following?

• A. Trim And FPS
• B. Attitude Hold And Hover
• C. Pitch Hold And Yaw Control
• D. Collectives Hold And Nose Wheel

Answer: (A)

Basic autopilot functions aim to reduce pilot workload by stabilizing the aircraft and relieving control forces. The two core elements are trim and flight path stabilization. Trim automatically adjusts the flight controls to eliminate the need for constant pressure by the pilot, so the aircraft tends toward a steady state without nonstop input. Flight Path Stabilization keeps the helicopter following a commanded path, automatically correcting for disturbances and maintaining the desired trajectory rather than a fixed attitude. This combination provides steady flight with less hands-on control. The other options describe capabilities that aren’t the foundational autopilot functions. Holding a specific attitude or hovering depends on more advanced or separate systems than the basic autopilot. Hold of pitch or yaw, or actions focused on the collective or landing gear, aren’t the basic stabilization and trimming roles that define the autopilot’s simplest, most essential support.
