Page 8: Section 1 Overview
(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. -
Page 9: Analog Limitations
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. -
