What is the trim on an aircraft?
By definition, to “trim” an aircraft is to adjust the aerodynamic forces on the control surfaces so that the aircraft maintains the set attitude without any control input. While all axes of rotation are affected by aerodynamic forces, not all aircraft types are capable of being trimmed in all three axes.
How do trim Tabs work on aircraft?
A trim tab is attached to the trailing edge of an elevator, and it’s operated by moving a small control wheel in the cockpit. 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.

Why do airplanes need trim tabs?
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. Fixed trim tabs are most often encountered on the rudder or aileron of a light, single engine aircraft.
How do you control trim?
Hold the controls lightly as you trim the airplane up or down. Keep your eyes outside the cockpit and note changes in pitch. Continue making tiny trim changes to find the spot where little to no forward or back pressure is required from your hands on the yoke.
