What is the main function of a control lock?

The primary function of a control lock is to prevent accidental inputs when the aircraft is not in operation. This is crucial for safety, as any unintended movement of the control surfaces can lead to damages or create hazards during ground operations. Control locks help ensure that the pilot or any ground personnel do not inadvertently affect the aircraft's control surfaces while the plane is parked or undergoing maintenance.

By securely locking the controls, it protects the integrity of the aircraft's systems and reduces the risk of accidents. This function is especially vital during pre-flight checks and while the aircraft is stationary, where any unauthorized or unintended manipulation of the controls could result in accidents or mishaps.
