In flight control terms, what does the AFCS provide when FPS is engaged?

• A. Basic autopilot functions
• B. Navigation system
• C. Engine torque control
• D. Vertical speed control

Answer: (A)

Flight Path Stabilization means the AFCS automatically stabilizes the helicopter and provides autopilot-like control to dampen disturbances and keep the aircraft on a steady flight path. With FPS engaged, the system handles the essential autopilot tasks—smoothing out pitch and roll inputs and maintaining a stable attitude so the pilot isn’t required to constantly trim manually. It isn’t designed to give navigation guidance, which comes from the navigation system, nor does it directly control engine torque. While the flight path objective can involve vertical movement, FPS’s primary role is basic autopilot stabilization rather than a dedicated vertical speed control mode. So, the AFCS with FPS essentially provides basic autopilot functions.
