What type of control surface is used for trim adjustments?

Trim tabs are specifically designed to adjust the neutral position of control surfaces, allowing pilots to maintain steady flight without continuous input on the control yoke or stick. These small movable surfaces can be found on various primary flight controls, such as ailerons, elevators, and rudders, and they help to relieve control pressures, enabling the aircraft to fly hands-off in certain configurations. By adjusting trim tabs, pilots can fine-tune the aircraft's response, making it more stable and reducing workload during flight. This function is distinct from flaps, spoilers, and ailerons, which serve different purposes related to aerodynamic lift and turning mechanics.
