What issue may arise if control surfaces are not properly aligned during rigging?

When control surfaces are not properly aligned during rigging, it can lead to unexpected flight performance and control issues. Proper alignment of control surfaces such as ailerons, elevators, and rudders is critical for the aircraft to achieve optimal aerodynamics and responsive handling during flight. Misalignment can create unintended drag, cause the aircraft to behave unpredictably, and can lead to challenges in maintaining stable flight paths.

For instance, if an elevator is misaligned, it may not be able to provide the correct pitch control, which can result in an aircraft that is difficult to fly, requiring greater pilot input to maintain level flight or perform maneuvers. Similarly, misaligned ailerons can create a rolling tendency, causing one wing to rise higher than the other, leading to potential loss of control.

Thus, ensuring that control surfaces are properly aligned during rigging is essential for safe and predictable flight operations. This focus on alignment directly impacts flight safety and performance, contributing to the overall effectiveness of the aircraft in various flight scenarios.
