If AFCS is coupled to the FD, torque limitations are applied to the FD system.

• A. True
• B. False
• C. Not Applicable
• D. Unknown

Answer: (A)

When the Automatic Flight Control System is coupled to the Flight Director, the flight path guidance is carried out through the AFCS actuators. Those actuators have a defined torque envelope, so any commands from the FD must operate within that envelope. To protect the controls and ensure safe, predictable handling, the AFCS imposes torque limits on the FD command path. If the FD tried to demand more than the actuators can deliver, the limits prevent overloading or rapid, unsafe motion, effectively rate-limiting and saturating the FD output as needed. That means torque limitations are applied to the FD system whenever AFCS is coupled, making the statement true.
