Which flight-control arrangement connects the rudder and ailerons with interconnected springs to counteract adverse yaw and can be overridden if a slip is necessary?

• A. Trim tab system
• B. Coupled ailerons and rudder
• C. Spoilerons
• D. Fly-by-wire protection

Answer: (B)

When you roll the airplane, the outside wing tends to drag the nose in the opposite direction due to adverse yaw. The arrangement in question uses a mechanical link between the ailerons and the rudder with springs so that as you command a roll, a compensating rudder deflection is automatically produced to counter that yaw. This makes turns more coordinated without extra pilot input, and it can be overridden when a slip is necessary by applying rudder independently.

The other options don’t describe this roll-to-yaw interconnection: a trim tab system only adjusts neutral surfaces, spoilerons use spoilers for roll instead of linking to the rudder, and fly-by-wire protection refers to electronic safeguards rather than a physical coupling of control surfaces.
