What is the primary benefit of using trim during flight in the DA20-C1?

• A. Reduces engine wear
• B. Increases fuel efficiency only
• C. Improves stall resistance
• D. Reduces control pressure, helps maintain stable flight, and improves efficiency and situational awareness

Answer: (D)

Trim changes the aerodynamic force on the elevator so the airplane can hold a desired pitch with much less manual effort. That means you can maintain level flight, a steady climb or descent, and a consistent airspeed without constant wrist and arm pressure. With the aircraft holding its attitude more automatically, the pilot’s workload decreases, which makes the flight feel steadier and allows you to focus on planning, scanning for traffic, and other situational awareness tasks. Because the elevator is set to a more efficient deflection, drag is reduced compared to constant control input, which also helps overall efficiency. Trim isn’t about changing engine wear or directly altering stall characteristics; it’s primarily about easing control, stabilizing flight, and improving efficiency and awareness.
