Which input should be made to prevent the upwind wing from rising during landing roll?

To prevent the upwind wing from rising during the landing roll, making more aileron input is essential. When an aircraft is landing in crosswinds, the upwind wing tends to be lifted due to the wind's force acting on it. By applying additional aileron input, you can counteract this tendency, effectively lowering the upwind wing and maintaining balanced flight. This input helps to ensure the aircraft remains level on the runway, reducing the risk of losing control during the landing roll.

Other options such as less wing loading, increasing flap settings, or throttle reduction do not directly address the issue of wing lift in crosswind conditions. Wing loading pertains to the aircraft’s weight distributed over its wing area, and reducing it does not influence the immediate aerodynamic response needed during landing. Increasing flap settings can also change the lift characteristics of the aircraft but is not a tactical response to correcting wing balance post-landing. Throttle reduction primarily affects thrust rather than lateral stability in crosswind conditions.
