1.2. PURPOSE
This pilot guide provides pre-ight and in-ight operating procedures for the
S-TEC 3100 autopilot (3100) for both digital and analog interfaced systems.
NOTE:
The S-TEC 3100 is designed to assist pilots with cockpit workload
management. The ability of the 3100 to provide optimum assistance
and performance is directly proportional to the pilot’s knowledge of its
operating procedures. Therefore, it is highly recommended that the pilot
develop a thorough understanding of the 3100, its modes, and operating
procedures in visual meteorological conditions (VMC) prior to using it
under instrument ight rules (IFR).
1.3. GENERAL CONTROL THEORY
The S-TEC 3100 is capable of being a two- or three-axis attitude-based
digital ight control system. It is comprised of a computer/programmer,
which performs input/output processing and control laws, and an integrated
bezel/display for mode selection and display, including trim annunciations.
S-TEC servos are coupled to the control system:
Roll Servo: Coupled to the ailerons. The 3100 senses roll attitude, roll rate,
heading error, and course deviation to control the roll servo.
