Which component adjusts the stabilizer to give nose-up setting for takeoff?

• A. STAB Trim
• B. Elevator trim
• C. Aileron trim
• D. Rudder trim

Answer: (A)

Trim systems let you set a desired pitch without holding back pressure. For a takeoff nose-up setting, the horizontal stabilizer is adjusted by the stabilizer trim, which changes the angle of the stabilizer plane itself to create a nose-up moment. This reduces the amount of back-pressure you need on the control yoke and helps the airplane reach the proper takeoff attitude with less effort. Elevator trim would tweak the elevator surface to change pitch, but it is not the mechanism that sets the stabilizer’s incidence. Aileron trim and rudder trim control roll and yaw, respectively, not pitch.
