This document discusses different types of trim tabs used on aircraft. It describes the location of trim tabs on elevators, rudders, and ailerons. Elevator trim tabs help balance control forces and maintain the desired angle of attack, especially during slow flight. Elevator trim tab position determines whether the elevator is pushed up or down. Rudder and aileron trim tabs counter the effects of slipstream or an off-center center of gravity from uneven fuel levels or passenger weight. Types of trim tab systems include elevator trim tab systems and rudder trim tab systems.

Elevator Trim Tab System
Elevator trim balances the control force necessary to
maintain the aerodynamic down force on the tail. When
aircraft is flying, a lot of trim could be required to maintain
the desired angle of attack. This mainly applies to slow flight,
where maintaining a nose-up attitude requires a lot of trim.
An important design parameter for aircraft is the stability of
the aircraft when trimmed for level flight. Any disturbances
such as gusts or turbulence will be damped over a short
period of time and the aircraft will return to its level flight
trimmed airspeed.

Rudder and Aileron Trim Tab System
Trim doesn't only apply to the elevator, as there is also trim
for the rudder and ailerons. The use of this is to counter the
effects of slip stream, or to counter the effects of the centre
of gravity being to one side. This can be caused by a larger
weight on one side of the aircraft compared to the other,
such as when one fuel tank has a lot more fuel in it than the
other, or when there are heavier people on one side of the
aircraft than the other.
