SECTION 5 - PERFORMANCE No change S-TEC SYSTEM 30 AUTOPILOT INTEGRATED SECTION 6 WEIGHT AND BALANCE See the current weight and balance information for the airplane with the autopilot and Aspen EFD1000 PFD installed. SECTION 7 AIRPLANE AND SYSTEM DESCRIPTION S-TEC AUTOPILOT SYSTEM The System 30 is a pure rate autopilot which uses an inclined rate gyro in the Turn Coordinator instrument as the primary roll and turn rate sensor. The turn coordinator includes an autopilot pick-off, a gyro RPM detector, and an instrument power monitor. Low electrical power will cause an instrument flag to appear while low RPM will cause the autopilot to disconnect. The autopilot includes a pre-flight test feature that allows a visual check of all the annunciator lamps. On the Liberty XL-2, the System 30 autopilot integrates with an Aspen EFD1000 Primary Flight Display (PFD) EFIS. The installation consists of the following components: Turn Coordinator/Mode Programmer Provides basic flight information, autopilot mode switching, and autopilot mode information. Autopilot Master Switch Selects the autopilot ON or OFF. Also starts the pre-flight test when selected ON and resets autopilot. Aspen EFD1000 PFD Provides course deviation information to the autopilot. Aspen Analog Converter Unit (ACU) Provides an interface between the PFD and GNS radios and the autopilot computers. GPS Annunciator Panels Provides GPS status information for the pilot. Roll Servo Provides actuation of the ailerons when the roll modes are selected on the autopilot.

Pitch Computer Takes inputs from the absolute pressure transducer and outputs signals to the pitch servo during altitude hold mode. If the accelerometer installed in the pitch computer senses a g-loading deviation from level flight in excess of ±0.6g, the pitch computer will automatically disconnect the autopilot. Absolute Pressure Transducer Receives ambient static pressure from the aircraft static system and converts it to electrical signals and provides that information to the pitch computer for use during the altitude hold mode. Pitch Servo Provides actuation of the elevator during the altitude hold mode. The preflight test feature is operated by use of the autopilot master power switch located on the avionics panel. When the autopilot master power switch is ON and the rate gyro RPM is correct, the green RDY light will illuminate indicating the autopilot is ready for the functional check and operation. The autopilot cannot be engaged unless the RDY light is illuminated. Once ready, the autopilot mode switch may be pressed to engage ST, HD, HI-TRK, or LO-TRK modes of operation. Pitch axis control of the System 30 is provided by a pressure transducer, pitch computer containing an accelerometer. When the altitude hold mode is engaged, an elevator trim sensor in the pitch servo will detect the elevator trim condition. When elevator trim is necessary to re-establish a trimmed condition, trim indicator lights on the turn coordinator face will illuminate to indicate the corrective trim required. If no action is taken for more than five (5) seconds, the light will begin to flash and an audible tone will be sounded to indicating a trim corrective action is required. P/N 135A-970-531 EASA Approved: June 23, 2011 Section 9 Initial Release Page 19 of 22
Turn Coordinator/Roll Computer The following are the annunciators and controls of the autopilot: Mode Select/Disconnect Switch Located on top left part of turn coordinator. Each momentary push of the knob will select an autopilot mode (ST, HD, LO-TRK, HI-TRK). Turning the knob left or right in stabilizer (ST) mode will provide left/right commands to the autopilot, proportional to knob displacement up to 90% of a standard rate turn. Holding the knob in for more than 2 seconds will disconnect the autopilot. Green Ready (RDY) Light Illuminates when the gyro has reached its operating RPM and the autopilot is ready to be engaged. Blue Altitude (ALT) Light Illuminates when the Altitude Hold mode is selected and engaged. A roll mode must be selected before the Altitude Hold function will engage. If a roll mode is not selected the altitude hold mode will be disabled until a roll mode is selected. Yellow Stabilizer (ST) Light Illuminates when the Stabilizer Mode is selected and engaged. The mode select knob, when centered, holds wings level. When turned left or right it sends a proportional turn command to the roll servo. It activates the turn command for roll axis maneuvers up to 90% of a standard rate turn. The turn command function is inactive in HD, LO- TRK, and HI-TRK. Section 9 EASA Approved: June 23, 2011 P/N 135A-970-531 Page 20 of 22 Initial Release
Heading (HD) Mode Illuminates when the Heading Mode is selected and engaged. The autopilot receives heading error information from the Directional Gyro (un-slaved). This heading error is the difference between the position of the heading bug and the nose of the aircraft. When in HD mode the autopilot will perform a turn to keep the heading but aligned with the nose of the aircraft. Low Gain Track (LO-TRK) Mode Illuminates when the Low Gain Track (LO-TRK) mode is selected and engaged. This mode is primarily for VOR cross-country navigation. The low gain minimizes autopilot responses to needle deviations. This will prevent over-correction in areas where low elevation or extreme distances from a VOR causes the needle to become noisy or have a scalloping effect. High Gain Track (HI-TRK) Mode Illuminates when the High Gain Track (HI-TRK) mode is selected and engaged. This mode is to be used for Localizer approaches, GPS tracking, and VOR approaches. TRIM UP Indicates the aircraft is out of trim nose down and requires elevator UP trim. TRIM DN Indicates the aircraft is out of trim nose up and requires elevator DN trim.
