What does a FLAP ASYM annunciator indicate?

A FLAP ASYM annunciator indicates an asymmetry of the main flaps. This warning occurs when there is a discrepancy in the position or operation of the flaps on one side of the aircraft compared to the other, which can lead to aerodynamic issues during flight. Asymmetrical flaps can affect lift and drag, potentially compromising the aircraft's handling and stability. Understanding this warning allows pilots to take appropriate action, such as performing a checklist, assessing flap functionality, or making decisions about flight safety.

Other options describe issues related to the flap system but do not specifically address the indication of asymmetry, which is the critical aspect of what the FLAP ASYM annunciator alerts pilots to monitor.
