Elevator forces may be balanced using the trim. True or False?

Elevator forces may be balanced using the trim. True or False?

• A. True
• B. False
• C. Not applicable
• D. Unknown

Answer: (A)

Trim systems are used to relieve the pilot from holding constant elevator input by creating a small aerodynamic force that balances the forces on the elevator itself. A trim tab deflects the elevator slightly, producing a moment about the aircraft’s center of gravity that counteracts the aerodynamic moment the elevator would otherwise create. This lets the airplane maintain its pitch attitude with minimal stick force, improving comfort and reducing pilot workload. On the DA20-C1, using the elevator trim to set a stable pitch means the elevator forces are effectively balanced, so the statement is true.
