During a roll, when one wing dips, what happens to lift on that wing and the opposite wing?

• A. The dipped wing has less lift; the opposite wing has more lift
• B. The dipped wing has more lift; the opposite wing has less
• C. Both wings produce equal lift
• D. Both wings lose lift

Answer: (A)

When a roll happens, the lift produced by each wing becomes unequal due to the bank angle. The wing that dips downward faces a less favorable flow for generating lift, so its lift decreases. The opposite wing, which rises, meets the air at a more favorable angle of attack and ends up producing more lift. This difference in lift between the two wings creates and sustains the roll—the dipped wing has less lift, the opposite wing has more.
