How can a left wing heavy condition be corrected in an airplane's flight?

A left wing heavy condition in an airplane refers to an imbalance where the left wing generates more lift than the right wing, potentially causing the aircraft to roll to the left. To correct this condition effectively, adjusting the angle of incidence of the left wing or decreasing that of the right wing directly influences the lift produced by each wing.

By increasing the angle of incidence of the left wing, its lift will increase further, which could exacerbate the issue. Conversely, decreasing the angle of incidence of the right wing results in a reduction of lift on that side, allowing the left wing to balance with the right wing better. This process allows for controlled alignment and stability of the aircraft in flight.

The other options may help with stability or general performance, but they do not directly address the imbalance between the wings as effectively. Adjusting speed can have an influence on lift, but it does not correct the inherent asymmetry in the wing lift. Adjusting fuel distribution and changing trim settings are more about managing overall balance rather than directly correcting a left wing heavy condition specifically. Therefore, modifying the angle of incidence on one of the wings is the most targeted solution to achieve balance and maintain controlled flight.
