Trio

The Gold Standard servo is unique in the industry. When Trio introduced the altitude hold systems, we did so only when we felt that we had designed a "safety-conscious" servo that we were comfortable connecting to an aircraft elevator system. (It is used for both aileron and elevator systems).

The Gold Standard servo has inherent "intelligence" capability acquired by the two internal microprocessors that govern its operation. It has full authority to disconnect itself from the controls if it senses anything that deviates from normal operational conditions. It watches motor driver currents and temperatures (both servo and auto-trim) as well as short circuits. It monitors crank arm positions and will disconnect (and alert the pilot) in abnormal circumstances - i.e. extreme elevator/aileron positions. It obeys the "G" force limitations dictated by the A/H control electronics and it will disconnect itself if it detects a communications error. It has a slip clutch to allow pilot override in emergency situations. It fully disconnects the internal gears when not engaged and the pilot will not feel any "system drag".

In short, the Gold Standard servo borders on being paranoid about your safety.
