What is the result of a down-going aileron compared to an up-going aileron during a roll?

In the context of aircraft maneuvering, ailerons are critical control surfaces that affect the roll of the airplane. When one aileron moves down, it increases the lift on that wing while causing drag, while the opposite aileron moving up reduces lift and also generates less drag. The down-going aileron creates a larger camber on the wing it controls, thus increasing lift on that wing. However, this increased lift is accompanied by increased drag due to the higher angle of attack and the disturbance in airflow.

Consequently, the down-going aileron does indeed produce more drag than the up-going one. This drag can influence the aircraft's performance during a roll, as the wing with the down-going aileron experiences both higher lift and higher drag, while the up-going aileron leads to a reduction in lift and drag. Aerodynamically, this dynamic is essential for understanding how the aircraft rolls and maintains stability.

The other options do not align with the fundamental aerodynamic principles involved in the functioning of ailerons during a roll. Therefore, choosing the statement regarding the increased drag from the down-going aileron accurately reflects the underlying mechanics at play.
