GPSS does not follow a CDI needle movement; it flies direct right/left steering commands from the GPS for extremely accurate, hands off GPS navigation.
In GPSS mode the autopilot will accept the steering commands from the GPS unit without any further input from the pilot. While in GPSS mode, the autopilot annunciates NAV GPSS. GPSS will not function unless a valid 429 digital roll steering signal is available. Lack of a solid signal causes the GPSS annunciator to flash.The GPSS Converter upgrades any existing S-Tec autopilot to include the GPSS function.
The GPSS converter is configured in three different physical packages: Horizontal panel mount, case contained; Vertical panel mount, case contained; and Remote mount control box with panel mounted switch.
The lighted panel switch selects GPSS or Heading mode. Note that if a valid roll steering command is not available, GPSS will not activate and this will be indicated by a flashing GPSS light.
In general aviation singles, light twins, and turboprops, S-TEC's rate based autopilot systems have a number of significant advantages over attitude based systems. You can expect safety, reliability, and performance whenever your autopilot is engage. S-TEC also believes in a building block philosophy which allows installation of an autopilot today as a foundation, and upgrading to a system with more features and functions at a later date. All S-TEC autopilot systems use common hardware, servos, and sensors throughout the product line which offers you significant advantages in serviceability, reliability, and overall cost. A multitude of autopilots are available from a simple altitude hold only to a full two axis autopilot with glide slope capture, vertical speed control, and dual mode intercept.
Manufacturer does not allow mail-order sales of Autopilots/Flight guidance systems to owners of Certified Aircraft. S-Tec Autopilots must be installed by an authorized S-Tec dealer, unless installed in a home-built aircraft. Avionics installations require special knowledge, skills, test equipment and tools.
