What aerodynamic issue can be worsened due to a swept wing design?

A swept wing design is known to enhance the performance of an aircraft at high speeds, primarily by delaying airflow separation over the wing. However, one of the aerodynamic issues that can be worsened with this design is control reversal. This phenomenon occurs when the aileron effectiveness is diminished at higher angles of attack, particularly in swept-wing aircraft.

As a swept-wing aircraft approaches its critical angle of attack, airflow can become disturbed, leading to a loss of control authority from the ailerons. This can result in unexpected movements contrary to pilot inputs, making the aircraft more challenging to control, especially during maneuvers close to the stall condition. Essentially, at higher angles of attack, the aerodynamic behavior of the wing changes significantly, which can lead pilots to experience control reversal more acutely in swept-wing designs compared to straight-wing aircraft.

While concepts like stalling height, interference drag, and wingtip vortices are relevant in aerodynamics, they do not have the same direct and critical impact regarding control authority as control reversal does in swept-wing aircraft.
