Which description accurately reflects the actions performed by the red autopilot disc button on the control wheel?

• A. Disconnect the autopilot
• B. Interrupt the stick pusher
• C. Reset the flight data
• D. Disconnect the autopilot and interrupt the stick pusher

Answer: (D)

The red autopilot disc button on the control wheel is a dual-action control: it immediately disconnects the autopilot and temporarily interrupts the stick pusher. Pressing it hands control back to the pilot and pauses the stall-protection response, giving the pilot direct manual control when needed. This combination is why the description that includes both autopilot disconnection and interruption of the stick pusher is the best fit. The other possibilities only cover one function or a different system, so they don’t fully describe what this button does.
