What is the role of the elevator trim in the Pilatus PC-12 NG?

The role of elevator trim in the Pilatus PC-12 NG is primarily to relieve control pressures during flight, which contributes to a stable cruise. The elevator trim allows the pilot to make minor adjustments to the aircraft's pitch without constantly applying force to the control yoke. This trimming function enhances flying comfort and reduces pilot workload by enabling the aircraft to maintain a desired pitch attitude with minimal input from the pilot, especially during long flights.

By using the elevator trim effectively, pilots can maintain level flight or a specific climb/descent rate more effortlessly. This is crucial for improving overall stability and efficiency during cruise, as it allows the pilot to focus on navigation and other tasks rather than continually managing control forces.
