What happens to flap function during asymmetric failure?

During asymmetric failure, the flap function can become uncoordinated due to the failure of one side's flap control system. This mismatch can result in one flap extending while the other retracts, which can lead to an imbalance in lift and affect the aircraft's handling characteristics.

Understanding this function is crucial in flight operations, especially under Part 135 regulations where safety and efficiency are paramount. In practice, such an asymmetric condition would necessitate careful management by the pilot to maintain aircraft control and performance, as uncoordinated flap positions could lead to increased drag and undesirable yawing moments.
