At first glance, it is difficult to tell the difference between the Sport SX, and our flagship, the Horizon HX. When equipped with the optional synthetic vision, the 10-
Your needs can change, but the Sport SX is ready for you. The starting price does not include synthetic vision, but all Sport SXs include a hi-

Often the days we fly do not require constant monitoring of the airplanes attitude. Airspeed, altimeter, and a map are all we need, with the PFD attitude to back us up if conditions change. We love those days and so does the Sport SX. That is why we allow you to show airspeed and altimeter tapes on your moving map. The Sport SX rounds everything out with wind and destination information.

The greatest value of obstacle alerting occurs when you find yourself forced to fly under an overcast in less than desirable visibility. At times like this, it must be effortless to understand such threats. That is why we show your threats on the PFD and not just the map. We show you the threat in the exact place you will be looking-
Comprehensive Engine Monitoring
Having produced the EIS engine monitor for over 20 years, we’ve accumulated a great deal of personal and customer engine monitoring experience. From this came such exclusive features as the exhaust gas temperature (EGT) time history. A simple graph of the last two minutes of all EGTs, our engine monitoring system makes it effortless to distinguish between engine problems affecting one cylinder, or the entire engine. This distinction could be essential when making decisions in response to engine problems, especially at critical times such as initial climb out. We find it so useful that we never takeoff without it displayed, and we recommend you don’t either.
CHT time history also proves useful by making the trend obvious. This is especially useful in high-
Finally, we love the specific fuel consumption display. Its measure of engine efficiency that confirms when you have leaned properly, and tells you when you need to lean again.
Dual rotary knobs and 5 lighted softkeys make up the pilot interface. All are high tactile force, which is optimal for operation in turbulence. The bezel includes a hand rest that further enhances ease of use when things get rough. Primary knob functions are heading selection and baroset. Pressing any softkey brings up secondary knob functions and softkey labels. Simple, effective and efficient.
Situational Awareness without Synthetic Vision
Deferring synthetic vision does not mean you are sacrificing situational awareness. The Sport SX shows obstacles and runways on the screen as they appear out the window, even without the synthetic vision. The highway-
The Source of the Attitude
The integrity of an EFIS is dependent on the integrity of the attitude data that drives it. GRT Avionics has always lead the way with the only AHRS in the industry that can operate without airspeed or GPS aiding. The same adaptive AHRS that is used in our stand-
The Connectivity You Need
Five serial ports in and out and a USB port allow for great flexibility within your panel design. An optional ARINC 429 interface can be added, while still retaining all serial ports, for connectivity with IFR GPS navigators, such as the G430/650/750.
The Sport SX includes full autopilot functionality. Just add GRT servos and you are on your way to a fully automated cockpit. Like our GRT EFIS systems, it can also control an external autopilot. Even without servos, all autopilot functions are available to drive the flight director, giving you a single cue to follow to control attitude and navigation, greatly improving accuracy while reducing workload.

Already own an autopilot? Just wire it to the Sport SX, and the Sport will couple it to all your navigation sources!
Engine Data with a Bonus
Engine data is provided to the Sport SX via the Engine Information System (EIS). The EIS is a complete instrument with a display and user-

We support that!
We are also kitplane builders, and have always supported the spirit of experimental aircraft by providing the builder with as many options as possible. This is why we provide free software support for the Sport SX for the following equipment:
(If there is a device that you don’t see on this list, and you would like the SX to interface with it, drop us a line! We are always willing to consider new devices, and thanks to the extensive interfacing and powerful processor within the SX, future growth is built-

The Sport SX is available in 6.5” and 8.4” screens, with the 8.4” being the most popular. Both feature the sunlight-
Easy Upgrade Path from Older Horizon Systems
The Sport SX shares the same wiring as our previous Sport systems. (Note: Gray Code altitude encoding is not supported by the Sport SX.) Click here for the upgrade price list.
Sport SX Highlights
“I flew the Sport today for the first time. All I can is say is wow. I have only scratched the surface of what it can do but I’m very impressed! It works flawlessly….Every function of the EIS worked perfectly on the first flight (a first for me). It adds a quality feel to the cockpit!”
