What are the travel limits of the ailerons of Cessna model 182L?

The travel limits of the ailerons for the Cessna model 182L are specified as Up 20º ± 2º and Down 15º ± 2º, making this option the correct answer. These limits are crucial as they ensure the aircraft can achieve the proper roll response during flight while remaining within the airframe's structural limits.

Keeping the aileron deflections within these specified limits also contributes to the stability and handling characteristics of the aircraft. If the ailerons were to exceed these travel limits, it could lead to undesirable flight characteristics, reduced controllability, and potential structural damage to the wings or control surfaces.

Knowledge of these specifications is essential for maintenance personnel and pilots alike to ensure that control surfaces are functioning correctly and safely, which directly impacts the overall performance and safety of the aircraft.
