Final answer:
When hand-flying the aircraft, the rudder can be trimmed to maintain coordinated flight. Trimming the rudder involves adjusting its position to counteract yawing motion caused by uneven airflow. Rudder trim helps with maintaining coordination and reducing undue stresses.
Step-by-step explanation:
When hand flying the aircraft, the rudder can be trimmed to maintain coordinated flight. Trimming the rudder involves adjusting the position of the rudder to counteract any yawing motion caused by uneven airflow over the aircraft. This helps to keep the aircraft flying straight and level.
To trim the rudder, the pilot would use the rudder trim tab or the rudder pedal position to adjust the rudder's position. The rudder trim tab is a small, adjustable surface on the trailing edge of the rudder that can be moved to offset any yawing tendency. The pilot can also use the rudder pedals to apply continuous pressure in the direction opposite to the yawing motion to achieve trim.
It is important to note that the rudder trim does not directly control the aircraft's direction of flight like the ailerons or elevator. Instead, it helps with maintaining coordination and reducing any undue stresses on the aircraft's structure.
