Part 23 requires this to overcome jamming of flight controls

Backup hydraulic system Redundant autopilot Redundancy or separation of primary flight controls Manual mechanical interlocks

Correct Answer:

Redundancy or separation of primary flight controls

Explanation:

When flight-control reliability is at risk from a jam, having multiple independent paths or physically separated control routes for the primary surfaces is essential. Redundancy means there’s a second, independent way to move each primary surface, so if one path sticks or fails, the other can still steer the aircraft. Separation ensures that a single event can’t simultaneously affect all control paths, reducing the chance that a jam knocks out all pitch, roll, and yaw control. This design approach is what Part 23 requires to maintain controllability after a jam. A backup hydraulic system, an autopilot redundancy, or manual interlocks don’t directly guarantee continued pilot control in the same way efficient, independent control paths do.
