This two axis autopilot combines Altitude Hold with the roll axis functionality of the System 20. It is designed to provide an economical solution for aircraft owners who need Altitude Hold, but don't want the additional functions of pitch command, vertical speed control or GS coupling.

• Independent system does not require interfacing to the altimeter or attitude gyro; derives all input from solid state absolute pressure transducer and accelerometer.
• Compact, remote mounted pitch computer and amplifier.
• When engaged, smoothly holds existing altitude; can be activated during climb or descent.

System senses out-of-trim conditions and annunciates direction to adjust pitch trim. Utilizes single, remotely-mounted On/Off switch to engage and disengage Altitude Hold. Heading Hold Requires Optional DG w/heading bug or HIS

Removed in good working condition from a 2003 RV-7A with 850 hours for a panel upgrade.  Includes pitch servo, roll servo, pitch computer, altitude pressure transducer, turn and bank coordinator and D-sub connectors.
