Which statement about elevator trim tabs is true?

• A. The elevators do not have trim tabs
• B. The elevators have trim tabs controlled by the autopilot
• C. The elevators have trim tabs operated by the flight crew manually
• D. The elevators are equipped with trim tabs that adjust automatically with airspeed

Answer: (A)

Trim is used to balance aerodynamic forces on the tail so you don’t have to hold constant stick pressure. On the Beechjet 400A, there are no trim tabs on the elevators themselves; the aircraft trims using the horizontal stabilizer trim system instead. That means the elevators do not have their own trim tabs and trim commands go to the stabilizer (often electric) and can be influenced by the autopilot or cockpit trim controls.

So the statement that the elevators do not have trim tabs is the correct one because the Beechjet’s trimming is accomplished on the stabilizer, not on individual elevator trim tabs. The other options imply the existence or control of elevator trim tabs, which isn’t how this aircraft is configured.
