STEC/Cobham Auto Pilot Systems and Components

Single Axis Auto Pilots (Roll Axis Only)
System 20 Auto Pilot
	The S-TEC System 20 Auto Pilot is a single axis Auto Pilot that can reduce the pilot workload in the cockpit by offering roll stabilization, heading input (with qualified heading input), and Nav Trac from an accepted Nav or GPS system. The System 20 is a great option for aircraft that have limited panel space to work with. MORE INFORMATION
System 40 Auto Pilot
	The S-TEC System 40 Auto Pilot is a single axis Auto Pilot that can reduce the pilot workload in the cockpit by offering roll stabilization, heading input (with qualified heading input), and Nav Trac from an accepted Nav or GPS system. The System 40 offers the same great features as the System 20 by offering a stand-alone Turn Coordinator and separate 3 ATI Auto Pilot Controller. MORE INFORMATION
System 60-1 Auto Pilot	Go to top of page
	The S-TEC System 60-1 Auto Pilot is a single axis Auto Pilot that can reduce the pilot workload in the cockpit by offering heading mode, (with qualified heading input), VOR/LOC intercepts and tracking, LOC back course intercept and tracking, flag warning, course deviation warning, and three level automatic radio coupler gain scheduling. The System 60-1 offers a stand-alone Turn Coordinator and separate 3 ATI Auto Pilot Controller. MORE INFORMATION

Two Axis Auto Pilots (Roll and Pitch Axis)
System 30 Auto Pilot
	The S-TEC System 30 Auto Pilot is a two axis Auto Pilot (Roll and Pitch) that can reduce the pilot workload in the cockpit by offering roll stabilization, heading input (with qualified heading input), Nav Trac from an accepted Nav or GPS system, Pitch Trim Annunciation, and Altitude Hold. The System 30 is a great option for aircraft that have limited panel space to work with, but want the most value for their investment. MORE INFORMATION
System 50 Auto Pilot	Go to top of page
	The S-TEC System 50 Auto Pilot is a two axis Auto Pilot (Roll and Pitch) that can reduce the pilot workload in the cockpit by offering roll stabilization, heading input (with qualified heading input), Nav Trac from an accepted Nav or GPS system, Pitch Trim Annunciation, and Altitude Hold. The System 50 offers the same great features as the System 30 by offering a stand-lone Turn Coordinator and separate 3 ATI Auto Pilot Controller. MORE INFORMATION

Full Function Two Axis Auto Pilots (Roll and Pitch Axis)
System 55X Auto Pilot
	The S-TEC System 55X Auto Pilot is a Full Function, two axis Auto Pilot that can reduce the pilot workload in the cockpit by offering heading mode, VOR/LOC intercepts and tracking, LOC back course intercept and tracking, flag warning, course deviation warning, vertical speed control, altitude hold, and Glideslope coupling. MORE INFORMATION
System 60-2 Auto Pilot
	The S-TEC System 60-2 Auto Pilot is a two axis Auto Pilot (Roll and Pitch) that can reduce the pilot workload in the cockpit by offering heading mode, (with qualified heading input), VOR/LOC intercepts and tracking, LOC back course intercept and tracking, flag warning, course deviation warning, vertical speed control, altitude hold, and Glideslope coupling. The System 60-2 offers a stand-alone Turn Coordinator and separate 3 ATI Auto Pilot Controller. MORE INFORMATION
System 65 Auto Pilot	Go to top of page
	The System 65 is a two-axis roll and pitch autopilot which includes heading mode, VOR/LOC/LOC back course intercept and tracking, glide slope capture and track, vertical speed command for climb and descent control, altitude hold, automatic elevator pitch trim, and VOR/LOC GS off course deviation warning.

Auto Pilot Accessories and Add-On Components
ST-901 GPSS
	As opposed to “tracking”, which essentially is reacting to signal input, GPSS anticipates course changes. When approaching a waypoint, for example, GPSS transitions to a new leg by anticipating arrival at the waypoint, and initiating a coordinated turn so that the aircraft is established on the new heading without overshooting or under-shooting the new course. MORE INFORMATION
System 30 ALT	Go to top of page
	The 30 ALT can be installed as stand-alone pitch axis autopilot, and can complement any brand of existing roll axis autopilot. The system 30 ALT is not dependent on aircraft altimeter or attitude gyro. Iinputs are derived from the systems’ solid state absolute pressure transducer and an accelerometer. MORE INFORMATION
System 60 PSS
	The 60 PSS can be installed as stand-alone pitch axis autopilot, and can complement any brand of existing roll axis autopilot. The 60 PSS can operate as an altitude hold, vertical speed and glideslope coupling system. The system 60 PSS is not dependent on aircraft altimeter or attitude gyro. Inputs are derived from the systems’ solid state absolute pressure transducer and an accelerometer. MORE INFORMATION
Yaw Damper	Go to top of page
	The Cobham yaw damper’s innovative design replaces the commonly used rate gyro with a highly accurate accelerometer, which virtually eliminates moving parts, except for the servo actuator. MORE INFORMATION
