Quiz: DHC-6-300 Systems: Flight Controls

Place the trim tab and geared (servo) tab labels to their correct positions.

You are looking inboard from the left wing tip. Drag the labels to their correct positions.

Only one of these DO NOT have a geared (servo) tab. Select the correct answer.

The ailerons [blank_start]lower[blank_end] with the wing flaps and their degree of movement, including the degree of differential movement, [blank_start]increases[blank_end] proportionately with flap deflection.

The purpose of this question is to briefly explain the difference between a trim tab and a geared (servo) tab. 1. A [blank_start]trim tab[blank_end] can be controlled from the flight deck, and its purpose is to create an aerodynamic force that keeps the flight control in a deflected position. 2. A [blank_start]servo tab[blank_end] is a small hinged device installed on an aircraft control surface to assist the movement of the control surfaces by moving in the direction opposite to the desired movement of the control surface, deflecting airflow, generating force on the whole control surface in the desired direction.
