In case of a mismatch between flap positions, what happens?

In the context of flap systems on aircraft, a mismatch between flap positions typically indicates that there is a discrepancy in the deployment of the flaps on either wing. In such cases, it is crucial to ensure that the airplane remains controllable and safe to operate.

When a flap position mismatch is detected, the system will often respond by disconnecting power to the electric motor that controls the flaps. This action is designed to prevent further movement of the flaps that could exacerbate the mismatch and create unfavorable aerodynamic conditions. By shutting off power, the system helps to stabilize the aircraft’s configuration and gives the pilot the opportunity to assess the situation without risking further complications.

This safety measure is essential because the flaps play a significant role in the lift and handling characteristics of the aircraft during critical phases of flight, such as takeoff and landing. Disabling the motor prevents any unintended or uncontrolled movements that could lead to difficulties in controlling the aircraft.

In summary, disconnecting power to the electric motor is a critical safety mechanism that helps to maintain control of the aircraft in the event of a flap position mismatch.
