What does the Automatic Flight Control System provide?

• A. Autopilot and automatic throttle control (ATC)
• B. Controls navigation systems
• C. Maintains cabin pressure
• D. Only allows manual flight control

Answer: (A)

The Automatic Flight Control System provides autopilot functionality along with automatic throttle control, meaning it can manage both the aircraft’s flight path and its airspeed without requiring continuous pilot inputs. The autopilot keeps the aircraft on the commanded trajectory by moving the flight-control surfaces as directed, while the auto-throttle adjusts engine power to maintain the desired speed or Mach number. This combination reduces pilot workload and improves stability, especially during complex maneuvers or long flights. Navigation and cabin pressurization are separate systems, so they’re not controlled by AFCS, and manual control can always be used when needed.
