Where is the Trim Disc control located?

• A. On the top of each control wheel
• B. On the center pedestal
• C. On the overhead panel
• D. At the flight deck door

Answer: (A)

The Trim Disc is located on the top of each control wheel. This placement lets you trim the airplane without taking your hands off the wheel, using a quick, tactile input with your thumb or fingers. Having a trim control on both wheels means either pilot can adjust trim as needed, which keeps flight control intuitive and responsive. Other locations like the center pedestal, overhead panel, or near the flight deck door aren’t as practical for trim inputs because they require reaching away from the wheel or are used for different systems altogether.
