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
What is aircraft trim?
Aircraft trim is an adjustment to the control surfaces
Better said, we can replace the word trim with “adjust” and get a similar meaning
When we “trim” an aircraft, we are adjusting one or more of the movable control surfaces so that the pilot doesn’t need to hold them with physical strength and can focus elsewhere
When should you use trim?
Possibly the most helpful use of trim is during the landing phase of the flight
It is a common technique to use pitch (using elevator trim) to achieve a certain airspeed, and use power/throttle adjustments to control altitude and descent rate
That technique can be seen and elaborated upon in this video:
If the aircraft is trimmed, the flight controls are in a state where no force needs to be exerted in order to continue straight and level flight. A...Best answer · 7
Trim is the control that adjusts the trim tab.
Effectively its a way to fine tune/change the control surface to elevate control forces.3
Aviation what is trim
Town in County Meath, Ireland
Trim is a town in County Meath, Ireland. It is situated on the River Boyne and, as of the 2022 census, had a population of 9,563. The town is noted for Trim Castle – the largest Norman castle in Ireland. One of the two cathedrals of the United Dioceses of Meath and Kildare – St Patrick's cathedral – is located north of the river. Trim won the Irish Tidy Towns Competition in 1972, 1984, 2014 and 2022, and was the joint winner with Ballyconnell in 1974. Trim was historically the county town of Meath, but this title was passed on in 1898 to the larger, neighbouring town of Navan.
Trim tabs are small surfaces connected to the trailing
Boat or aircraft component
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.
