What potential issue can arise from improper sealing of control surfaces?

Improper sealing of control surfaces can lead to decreased control authority due to air leaks. Control surfaces, such as ailerons and elevators, are designed to create specific aerodynamic forces when deflected. If there are leaks around these surfaces, it can cause a loss of effective control as the desired airflow is disrupted. This results in reduced responsiveness and precision when manipulating the aircraft's attitude or direction, making it difficult for the pilot to maintain control, particularly during critical phases of flight.

Ensuring that control surfaces are properly sealed is crucial for maintaining the expected performance and handling characteristics of the aircraft. Each surface needs to effectively channel and manage airflow to function optimally, and any interruption can translate into a significant compromise of maneuverability. Thus, the integrity of seals around control surfaces directly affects the aircraft's operational capabilities.
