Which statement is true about the stabilator position indicator powered by auto-transformers?

• A. It displays the stabilator position
• B. It controls stabilator actuation
• C. It monitors main rotor speed
• D. It displays airspeed

Answer: (A)

The stabilator position indicator exists to show the current angle of the stabilator. The pilot uses that feedback to know exactly where the stabilator is set, which helps with pitch control and trim without over-stressing the tail. The auto-transformers powering this indicator simply provide a reliable power source for the display. They ensure the indication remains available and consistent even if other electrical conditions fluctuate or some power sources are off. This is about powering the indicator, not controlling or moving the stabilator. So the indicator’s job is to display the stabilator position, not to actuate it, not to monitor rotor speed, and not to display airspeed.
