(IFR). 1.3. General Control Theory The S-TEC 3100 is capable of being a two- or three-axis attitude-based digital flight control system. It is comprised of a computer/programmer, which performs input/output processing and control laws, with an integrated bezel/display for mode selection and display, including trim annunciations.
The AP also includes an altitude pre-select function, if enabled. 1.4. Analog Limitations The S-TEC 3100 relies on digital air data information for advanced functions such as altitude pre-select. For analog configurations altitude hold is available, but the ALT target is not selectable.
Automatic Trim Mode: Automatically drives pitch trim servo. 1.6.3. Yaw Axis Control Yaw Damper (YD) Mode: Dampens excessive adverse yaw and coordinates turns (if installed) 1.7. Block Diagram Figure 1-2: Block Diagram (With Optional Yaw Damper) S-TEC 3100 Digital and Analog Rev A Nov 2018...

Table 3-2, the corresponding action engages heading mode. HDG appears. The AP turns the A/C onto the selected heading and holds it. A new heading can be selected thereafter by setting the heading bug to it. Rev A Nov 2018 S-TEC 3100 Digital and Analog...
The course is captured upon reaching the point where the AP must begin to turn the A/C onto the course. After completing the turn, the AP establishes the crosswind correction angle and tracks the course. S-TEC 3100 Digital and Analog Rev A Nov 2018...

For all other configurations, scrolling either concentric SELECT knob a single detent causes the current (captured) baro-corrected altitude to also appear in units of feet (ft.) (for example, 12500). The AP holds the A/C at the captured altitude. Rev A Nov 2018 S-TEC 3100 Digital and Analog...
1000 ft., whereas the inner knob changes in increments of 100 ft. Target altitude appears in units of ft. (for example, 12500) with ALT to indicate ALT HOLD mode is armed. S-TEC 3100 Digital and Analog Rev A Nov 2018...
“One Thousand to Go.” Once the point has been reached at which the AP must begin a scheduled reduction in VS, the target altitude is captured. CAP replaces the active annunciation Rev A Nov 2018 S-TEC 3100 Digital and Analog...
