What warnings does the flap control unit detect?

The flap control unit is designed to monitor and ensure the proper functioning of the flaps on an aircraft. Among the key functionalities of the flap control unit is its ability to detect conditions that could compromise the operation of the flap system. This includes detecting issues such as twisting of the flap mechanism, asymmetry in flap deployment (which can cause unequal lift), and failure or jamming of the flexible drive shaft that controls the flap movement.

These warnings are critical because they help the pilot identify potential mechanical problems with the flap system before they can lead to unsafe flight conditions. The ability to detect these specific warnings ensures that the aircraft can be operated safely and that corrective actions can be taken promptly. The other options relate to different systems or scenarios that are not monitored by the flap control unit.
