What is the function of the trim system in an aircraft?

• A. To aid in reducing fuel consumption
• B. To maintain aircraft attitude without constant control pressure
• C. To control airspeed during descent
• D. To improve wing performance

Answer: (B)

The trim system in an aircraft is specifically designed to assist the pilot in maintaining the desired attitude of the aircraft without requiring constant control pressure on the control stick or yoke. By adjusting the trim, the pilot can relieve themselves of the physical workload involved in maintaining flight stability. This is particularly helpful during long flights or when it is necessary to focus on other cockpit duties, as it allows the aircraft to stay in a specified attitude more comfortably. When the trim is properly set, it minimizes the need for the pilot to hold continuous pressure on the controls, thereby enhancing control efficiency and reducing fatigue. The primary objective of the trim system is to create a neutral position for the control surfaces, which enables the aircraft to fly straight and level with minimal input from the pilot.
