Do the elevators have trim tabs?

• A. Yes
• B. No
• C. Only on certain models
• D. Trim tabs are optional

Answer: (B)

Pitch trim on the Beechjet 400A is provided by moving the entire horizontal stabilizer, not by tabs on the elevator surfaces. The stabilizer trim actuator adjusts the tailplane angle to achieve the desired pitch, while the elevators themselves do not carry trim tabs. So there are no elevator trim tabs to set. The cockpit trim control and the autopilot work with the stabilizer trim to relieve control forces and maintain the selected pitch.
