The Steering Assist Module (SAM™) is a GPSS and Annunciator product consisting of a remote mounted computer, a panel mounted sunlight-readable transflective LCD Display, rotary knob, and audio toggle switch. There are multiple panel-mounting options for the display, rotary knob, and audio toggle switch, including a standard 2 ¼” round mount, a ½ ATI (King DME style) mount, and discrete components.

SAM provides GPS Roll Steering (GPSS) by converting a GPS ARINC 429 provided Roll Steering command to a heading error signal that emulates the existing heading error signal normally provided by the DG or HSI to the autopilot.

SAM is capable of providing verbal and visual annunciation of information such as waypoint passage, altitude targets and systems warnings (low voltage, low vacuum, check engine, check fuel, check oil pressure, stall and check gear) provided the appropriate inputs are interfaced and configured as described in this manual.

Any autopilot, AC (400Hz to 5Khz) or DC, that meets the specifications, with a functioning heading mode that supports a DG or HSI heading bug is compatible with SAM. The Garmin 155, 300, 400, 500, and 480 series all provide a compatible roll steering output as does the King KLN 900 and KLN 90B. Early models of the CNX-80 may not support ARINC-429 output, check with the installation manual. Other GPS receivers with ARINC 429 output may be compatible but it is the installer’s responsibility to verify the appropriate labels are supported and a thorough functional test should be performed on the installed system to ensure compatibility.

SAM includes the following interfaces:

ARINC 429 - A High/Low Speed ARINC 429 input is used to interface with a GPS to provide GPSS computation and Display/Annunciation of GPS data. Note: GAMA Flight Plan data require to support waypoint annunciations.

Heading Error Input/Output/Reference – A heading error output signal is provided to interface with an AC or DC autopilot heading error input. In heading mode a solid-state switch channels the heading error input signal to this output to allow normal heading mode operation of the autopilot. In GPSS mode this output emulates the DG/HSI heading error signal to provide roll steering functionality when the autopilot is in heading mode.

Heading Error Input connects to the Heading Error Output from the Directional Gyro or HSI Heading system.

A Heading Reference Input is required for AC heading sources to provide the appropriate phase output during GPSS steering.

A calibration procedure allows the emulated GPSS Heading Error signal to match the existing aircraft DG or HSI Heading Error signal.

RS232 Serial Altitude Input - Serial Altitude input is supported for both the ICARUS and Garmin UPSAT (Apollo) formats. Serial input is optional but required for Altitude Alert functionality.

Barometer Correction Input - Altimeters with Baro Correction Potentiometers are supported and allow automatic setting of Barometric pressure for Altitude Alerts. A calibration procedure is performed as part of the installation for the specific Altimeter. Baro input is optional.

Digital Inputs - Digital inputs are optionally available to interface with various aircraft systems to provide audio and visual alerts.

Audio Output – Audio output interfaces with the aircrafts audio panel to provide aural annunciations.

Audio Mute Input – An audio mute input is provided to allow manual or automatic muting of the aural annunciations.

Dimmer Input – The dimmer input allows the SAM display to track the aircrafts dimmer bus.
