What is the effect of washing in the left wing of a monoplane during rigging corrections?

Washing in the left wing of a monoplane during rigging corrections typically results in an increase in both drag and lift. This is because introducing wash-in (increasing the angle of incidence at the wingtip) alters the airflow around the wing. As the angle of attack of the wing increases due to wash-in, the lift generated by the wing also rises, potentially leading to a more pronounced lift distribution across the wing's span.

However, as lift increases, the drag also rises owing to the higher angle of attack. This increase in drag can impact the aircraft's overall performance, particularly during different phases of flight such as takeoff and climb. Therefore, modifications to wing rigging, such as adding wash-in, must be carefully considered, as they enhance lift but also lead to increased drag, which can affect speed and fuel efficiency.

The understanding of how wash effects interact with aerodynamic principles is crucial for optimizing flight performance and ensuring safety during aircraft operations.
