C. Description
The S-TEC System 55/55X is a rate based autopilot that controls the roll and pitch axis of the
aircraft. The autopilot's main function is to convert pilot commands to logic signals for the roll and
pitch computers. As the pilot enters the desired mode by pressing the appropriate mode selector
switch, the computer acknowledges the mode, causing the appropriate annunciator to illuminate.
The Roll Computer receives select input signals from the Directional Gyro (DG) or Horizontal
Situation Indicator (HSI), VHF Omnidirectional Radio (VOR), Localizer (LOC) or Global Positioning
System (GPS), Deviation Indicators, and the Turn Coordinator. It then computes roll servo
commands for stabilization, turns, navigation intercepts, and tracking.
