Genesys Aerosystems - New - SYS30ALT

Please call for a customized installation quote for your aircraft. For certified aircraft, S-TEC equipment must be installed by an authorized S-TEC dealer. Available to ship for experimental aircraft only.


The System Thirty ALT is a single-axis altitude hold autopilot, which can be installed as a stand-alone pitch autopilot, or to complement any brand of existing roll-axis autopilot system. It is designed to provide an economical solution for aircraft owners who need altitude hold, but don’t need the additional pitch functions such as vertical speed command or glide slope capture. Features include a small ¾ inch square, panel-mounted On/Off switch to engage the altitude hold function and annunciate out-of-trim conditions.

Building block concept allows upgrading to a System Thirty or a full two-axis System FiftyFiveX autopilot.
