English term or phrase: trim tab

Definition from skybrary:
Trim tabs are small, secondary flight control surfaces that are attached to the trailing edge of a larger, primary control surface such as an elevator or rudder. The trim tab is used to "trim", or counteract the aerodynamic force on, the control surface and thus stabilise the aircraft in the axis of rotation associated with the primary control. Trim tabs can be either flight adjustable or fixed.

Example sentence(s):

In the 2011 fatal accident, the elevator trim tabs began fluttering due to wear on part of the linkage. With the loss of an effective trim system, the aircraft abruptly pitched up with as much force as 17 Gs, which caused the pilot to black out. (After the pitch up, the trim tab separated from the left elevator.) airspacemag
When you move the trim tab up or down, it sticks out into the free air stream, and deflects the elevator in the opposite direction. So even though it may seem 'backwards' to move the tab down to make the nose of the plane go up, seeing the tab in action helps it all make sense. Boldmethod
Another advantage of using trim tabs is that they protect the airplane from premature wear and tear. If an airplane doesn’t have trim tabs, it will be exposed to greater stress and pressure during flight. Over time, constant exposure to this stress and pressure may cause some of the airplane’s components to fail early. Monroe Aerospace

Definition from lexico:
يستخدم هذا النوع من الأجنحة لتعديل جسم الطائرة أثناء الطيران والحفاظ على توازنها مما يسمح لها بالطيران بانسيابية.

Example sentence(s):

‘Such things as the wing tips, ailerons, trimming tabs, elevator, seats, berths and landing gear may be exchanged between one plane and another.’ - lexico
Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force. This is done by adjusting the angle of the tab relative to the larger surface. - https://en.wikipedia.org/wiki/Trim_tab
