S-TEC / Genesys 3100 Cardinal Autopilot Program

Information and Interest Indication

Sign up below!

Update! 1/28/18 S-Tec has announced a new benefit for all CFO members who place a purchase order for the 3100 before the Cardinal PMA is approved. Any CFO Member who signs up for this program on this page and also has your shop send a 3100 PO to S-Tec before the Feds issue their PMA approval will have their warranty extended to 3 years on the autopilot controller and 2 years of warranty on your existing servos.

Update! 12/18/17 The initial number of POs have been received by Genesis and the STC/PMA work is beginning as of today. We hope for a quick turnaround by the Feds!

Update! This program has met the initial interest goal to trigger next steps, please read on for details:

The autopilot market has become quite complicated recently, with several new players entering the marketplace. As we do with other products, your CFO leadership team has been working with many of the manufactures, seeking to keep the Cardinal in their sights as an aircraft worthy of the time and energy required for certification.

At Oshkosh Airventure 2017 Genesys Aerosystems (known to most of us from their S-TEC roots) announced their new S-TEC 3100 digital autopilot, a high featured and fully capable IFR autopilot containing the most advanced extras, along with a high level of integration with your existing navigation and control instruments.

When we asked where the Cardinal might be in their certification schedule they were very interested in how we might work together to help define the answer to that question.

We talk about many kinds of autopilots in our CFO conversation. Many new autopilots are designed for limited use in VFR conditions. We certainly welcome that class of autopilots to the market and support them actively for those people who will benefit from such an autopilot.

The Genesys Aerosystems 3100 is much different: it is a highly advanced autopilot for IFR operations with many operational and safety features and the deep integration which lesser systems lack. The kit supplied will include everything required for installation, including the electronics, cables, servos, controls, brackets and mounting hardware. The S-TEC 3100 must be purchased and installed through the Genesys Authorized Installation Center of your choosing.

Once certified the 3100 can be installed in a Cardinal as a new system or as an upgrade for a Cessna or any other autopilot. The Cardinal must have the aileron bellcrank which accepts an autopilot connection. This was installed in any Cardinal which came with an autopilot and can be retrofitted in the field.

This system is particularly interesting for those of us with existing S-TEC autopilots as there will be kits designed to allow the 3100 to upgrade your current installation, adding substantial functionality at an affordable price. Any S-Tec autopilot may be upgraded... the price for upgrade will vary depending in part upon what servos are already installed.

Genesys Aerosystems has just announced pricing details for the 3100. The 2-axis S-TEC 3100 for a fresh installation is $19,995 retail which includes altitude hold, autotrim and altitude preselect, as well as new features such as envelope protection and straight and level mode.

For those of us who currently have an S-TEC installed the upgrade price will depend on the equipment already installed (see below table.) This will be an outstanding bargain to get the benefits of a fully integrated digital autopilot, especially considering the additional safety features which it will bring.

Our first step in this process will be to gauge interest. Once we've seen a substantial indication of interest (They are currently talking about 15 systems as a starting point) some increased commitment will be expected from Genesys.

Upon that commitment (which we expect to include firm dates) we will need to make a matching commitment with individual purchase orders, naming a dealer each buyer expects to work through. With those commitments in hand Genesys will continue forward and we'll be on the path to having a certified digital autopilot for our Cardinals.

S-Tec is adding a benefit for this program: everyone who purchases a 3100 though the CFO program will be provided a 1 year warranty on your servos from the date of installation by S-Tec.

In addition: Many of us will want to have our existing servos IRAN'd to make sure they are in good shape to supply years of service with this new controller. For the first 15 PO holders, S-Tec will inspect your servos at a cost of just $100 per servo if no trouble is found. This is usually billed at $531.

Further, if repairs are required during this inspection they will be covered by your new 1 year warranty... so, no charge for those repairs and no inspection fee. This is an outstanding opportunity to get a completely refreshed autopilot system if you are one of the first 15.

And again the 1 year servo warranty will cover everyone who purchases through this program, a great benefit for everyone.

Additional information on the S-TEC 3100 autopilot:

The S-TEC 3100 is a Digital Flight Control System (DFCS), developed for FAA Part 23 single- and twin-engine aircraft. It is based upon the existing Level A S-TEC 5000 autopilot certified for larger aircraft.

Along with digital flight control, the 3100 will include envelope protection and one-button straight and level recovery.

The S-TEC 3100 was designed with open architecture to easily integrate with both legacy analog avionics such as HSIs and DGs and today’s advanced digital systems such as complete EFIS displays. In addition, it was designed to require minimal additional equipment to keep the incremental cost as low as possible.

Please note: This is a very important concept for CFO, as we believe in designs which allow flexibility of equipment selection. We don't all have the funds to build a perfect panel, so that's why companies such as Genesys, Aspen and Avidyne get our support over Garmin, who generally designs to exclude interoperability.

We also note that many of the new autopilot systems only interface with the GPS data output stream, not the other instrumentation in the airplane. The S-Tec 3100 will fully interface with your existing systems to provide fully integrated functionality. The next-generation S-TEC 3100 two-axis Digital Flight Control System also features:

- Built-in autopilot with flight director
- Flight director capability can drive pitch and roll flight director bars together with mode annunciations on compatible EFIS displays
- Lateral and vertical navigation functions including GPSL, GPSV, GPSS, VOR, LOC and GS
- Vertical navigation targets set on the bezel or compatible EFIS
- Heading Hold
- Altitude Preselect and Hold with Autotrim
- Vertical Speed Control
- Indicated Airspeed Control
- Under Speed and Over Speed Warnings
- Roll Envelope Exceedance Warning
- Automatic Pitch Trim
- Course Intercept capability
- Dual Mode – HDG/NAV and HDG/APR
- Control Wheel Steering
- GPS Steering (GPSS) Mode
- Voice Annunciations
- System can be integrated with approved legacy analog and digital avionics systems
- And more

At CFO we consider the Genesys Aerosystems S-TEC 3100 to be the ideal digital autopilot for IFR aircraft and pilots and encourage everyone with an interest to take this opportunity to help make the Cardinal one of the early certifications for this system.

Update! The program has reached a sufficient level of interest and has been launched. We are currently now all generating purchase orders with our avionics shops and following the other steps on the instruction page. If you have signed up please navigate to that page to see the required steps and follow them. Once a substantial number of POs are received S-Tec will submit the STC paperwork. We still appreciate new folks are are just coming along now, as greater numbers will still help the program.

Update! 12/18/17 The initial number of POs have been received by Genesis and the STC work is beginning as of today. We have hopes of a quick turnaround by the Feds!

Update! 1/28/18 S-Tec has announced a new benefit for CFO members who place a purchase order before the PMA is approved. If you have signed up for this program and have your shop send a PO to S-Tec before the Feds issue their PMA approval your warranty will be extended to 3 years on the autopilot controller and you will also receive 2 years of warranty on your existing servos.

Note that the instructions page is inside the member's area so as to protect email addresses and other information from access by those who are not known by the system.
