The most advanced autopilot for the most types of single- and twin-engine aircraft

Announcing the next-generation Genesys Aerosystems S-TEC 3100 Digital Flight Control System (DFCS). The S-TEC 3100 is a fully featured, attitude-based autopilot that gives you a list of workload-reducing and safety-enhancing capabilities that were previously unavailable on aftermarket autopilots. Compatible with advanced digital sources & EFIS displays from Garmin, Aspen and others, the S-TEC 3100 delivers unmatched features and benefits:
  • It’s been a long day and you’re nearing the end of your flight home. It’s getting dark. The weather is closing in – fast. Approach control is firing directions at you faster than you can copy them down. This is single-pilot IFR at it’s most difficult...for other pilots.

    Fortunately, you have a very capable “copilot” in the form of a next-generation Genesys Aerosystems Genesys 3100 Digital Flight Control System (DFCS).

    The Genesys 3100 is a fully featured, attitude-based autopilot that gives you a list of workload-reducing and safety-enhancing capabilities that were previously unavailable on aftermarket autopilots. The Genesys 3100 DFCS’s industry-leading features include:

    Envelope Protection/Alerting
    Loss of control is one of the largest contributors to general aviation accidents. The Genesys 3100 DFCS helps minimize the chance of entering into an inadvertent stall, unusual attitude, over-speeds or excessive banking situation caused by aggressive autopilot inputs.

    For example, should your aircraft approach a stall while the Genesys 3100 is engaged, the system will automatically alter the maximum pitch angle necessary to quickly return the aircraft to a safe speed. In addition, visual and aural annunciations will alert you to the situation.

    In situations where you encounter an over-speed or excessive banking, the system will apply similar corrective actions to mitigate these potentially hazardous situations.

    Straight and Level Recovery
    Should you inadvertently enter into an unusual attitude situation, the Genesys 3100’s Straight and Level button (LVL), delivers fast and simple automatic recovery to level flight from an unusual attitude no matter what the visibility. Once engaged, Straight and Level instantaneously overrides previous autopilot inputs to safely return and hold your aircraft at a neutral attitude while youget things sorted out.

    Indicated Airspeed Hold
    No matter what phase of flight you are in, Indicated Airspeed Hold (IAS) will reduce your workload. Set the power and trim and press the IAS button and the Genesys 3100 will automatically hold the precise airspeed you select. This is especially useful when flying around busy airports where the tower asks you to keep your speed up or slow down to accommodate traffic.

    Altitude Preselect
    Whether you’re departing or approaching the airport, between looking for traffic, talking to ATC and not busting an assigned altitude is one of the most stressful parts of flying. The Genesys 3100’s Altitude Preselect (ALT) feature can reduce your workload. It not only lets you preselect your desired altitude, it will give you both visual and aural alerts as you approach the setting or if you fly through it.

    Works Very Well with Others
    To ensure the easiest installation path possible, the nextgeneration Genesys 3100 is designed with open architecture to integrate with a wide array of legacy analog avionics, as well as, advanced digital sources and EFIS displays from Garmin, Aspen and others.

    Precise, Digital Flight Control for Every Phase of Flight
    No matter if you’re flying a single on a sunny Sunday or a high-performance twin down to minimums on a dark and stormy flight, the Genesys 3100 DFCS will make every phase of every flight easier, safer and more enjoyable.

    Precision Approaches/Missed Approaches
    Flying a solid precision approach or missed approach in low visibility is extremely stressful even for pilots who do it every day. The Genesys 3100 features GPS Steering (GPSS), which enables the aircraft’s GPS navigation system to accept roll steering commands from the system. The end result is extremely accurate, “hands-off” GPS navigation in high-workload situations. Additionally, by accepting commands directly from the GPS, the GPSS function enables the Genesys 3100 to not only fly very precise GPS courses, it also does an equally exceptional job of flying very precise, very stabilized GPS and missed approaches. Your passengers will be impressed.

The award-winning Aspen Evolution Pro MAX primary flight display (PFD) and the S-TEC 3100 autopilot by Genesys Aerosystems have created an autopilot solution to provide the highest level of safety and precision flying for general aviation aircraft.

Aspen’s Pro MAX PFD with the Genesys Aerosystems S-TEC 3100 Autopilot enhances and expands the basic S-TEC 3100 Autopilot function and streamlines the controls, reducing workload and removes the need for some external adapters. When combined with all the features and benefits of Aspen’s glass panel technology, flying becomes easier and safer, especially for single pilot IFR missions.
