If the same angle of attack is maintained in ground effect as when out of ground effect, the lift will:

Maintaining the same angle of attack while in ground effect leads to an increase in lift due to the influence of the ground on the airflow around the wing. Ground effect occurs when an aircraft is close to the surface, typically within a height roughly equal to the wingspan. This proximity to the ground restricts the downward flow of air around the wing, effectively reducing the wake and allowing for a more efficient lift generation.

In ground effect, the pressure beneath the wing is higher due to the reduction of the downwash, which leads to a significant increase in lift at the same angle of attack compared to when the aircraft is flying at the same angle of attack but at a higher altitude, where the downwash is more pronounced. This increase in lift in ground effect can also result in a decrease in induced drag, as induced drag is related to the lift being generated; thus, less induced drag is experienced when more efficient flow conditions are present.

Overall, the phenomenon of ground effect enhances lift and reduces induced drag when the angle of attack remains constant, making the increase in lift and the decrease in induced drag the correct interpretation of the scenario.
