Do PRI and SEC trim travel at the same rate?

The correct answer is that PRI and SEC trim do not travel at the same rate. In aviation, PRI (Primary) and SEC (Secondary) trim systems serve different functions and are designed to respond differently based on the aerodynamic conditions and aircraft configuration.

PRI trim is primarily used for more significant adjustments during various phases of flight, whereas SEC trim often provides finer adjustments for more precise control. Because each system operates independently and is calibrated for different performance criteria, their travel rates will vary based on input and aerodynamic forces acting on the aircraft.

Understanding the distinctions in the control system's design and purpose is crucial for pilots and maintenance personnel when assessing aircraft performance and handling characteristics. This differentiation is essential for safe and effective aircraft operation, particularly in high-performance scenarios where precise control is necessary.
