(aeronautical) a control surface set within or attached to a larger control surface that provides trim to obtain a desired attitude without constant inputs to the primary control surfaces (e.g., ailerons and rudders)
Had both trim tabs been operational, the loss of the left trim tab alone may not have caused loss of control.
Si ambas lengüetas de ajuste estuvieran operativas, la pérdida de la pestaña de ajuste izquierda sola puede no haber causado la pérdida de control.WikiMatrix WikiMatrix
