What is the primary benefit of using aileron trim?

The primary benefit of using aileron trim is that it alleviates pilot workload by reducing control stick pressure. Aileron trim allows the pilot to make small adjustments to the ailerons, which helps maintain level flight or a desired bank angle without requiring constant pressure on the control stick. In situations where a pilot may need to fly straight and level for an extended period, using aileron trim can help minimize fatigue by relieving the pilot from having to hold the controls in a specific position continuously. This is especially useful in longer flights or when dealing with turbulence, enabling the pilot to focus on other aspects of flying without the distraction of maintaining control input for roll stability.

While other options discuss roll control, climb rate, and yaw stability, they do not directly address the primary advantage of aileron trim, which centers around managing pilot workload and improving comfort during flight.
