What occurs when an aileron is deflected downward?

When an aileron is deflected downward, it increases lift on the wing. Ailerons are control surfaces located at the trailing edge of the wings, and their primary function is to control the roll of the aircraft.

When the aileron on one wing is moved downward, it changes the airflow around that wing, creating a difference in pressure compared to the other wing. This downward deflection causes that wing to generate more lift, allowing it to rise. In flight, this differential lift leads to the aircraft rolling toward the wing with the upward-deflected aileron, enabling pilots to maneuver effectively.

Understanding how ailerons work is crucial for flight attendants, as it provides context for the aircraft's operations and assists them in addressing passenger concerns about flight behavior. This knowledge helps foster a better understanding of aerodynamics and promotes safety awareness.
