Sport SX

Unmatched Value


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-mile vision range keeps you well aware of terrain, and generates 3-D way-points, obstacles and runways. Five serial ports and a USB provides for connectivity with ADS-B, com and navigation radios, autopilots and much, much more. The Sport SX includes the new Adaptive AHRS technology, digital magnetometer and internal GPS, and starting price of only $2600 makes this an unbeatable value for any the VFR or light IFR airplanes.


Upgradeable


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-speed processor that is synthetic vision ready. Optional vertical (lateral is included) autopilot/flight director functions can be added at any time without removing it from your airplane. Full interfacing to IFR GPS navigators, such as the G430/G650 is always available via the optional ARINC 429 module.  


Split-Screens


Ten split-screen combinations are included, combining two or three views into one screen of the PFD, map and HSI, and engine monitoring.  Information is clearly presented, making it practical to fly with a single screen and rarely touch a button. For dual screen installations the split-screens provide a single-screen reversionary mode suitable for IFR flight.







Above, the PFD shows the way-point on the horizon. The flight path marker shows the airplane in a slight descent (below the horizon water-line), tracking just to the right of the way-point. The flight director has been set to a 1000 fpm descent to 1600 feet. The flight director is commanding the pilot to pitch down (nestle the yellow chevron within the magenta) and make a very slight right roll to achieve the descent and 10 degree heading. Winds are a right cross-wind at 12 mph.


Dual-Screen Optimized


Dual screens were never an after-thought. The Sport SX was designed to function together, providing more information, interfacing and redundancy. Illustrated below are two screens configured for takeoff. We like displaying the EGT time history for takeoff.  It allows for differentiating between engine problems affecting a single cylinder, and those affecting the entire engine-potentially valuable data for making critical decisions.
















Below two Sports as they are configured after initial climb-out. The map now replaces the engine page, and the engine strip is shown on one of the screens. Either screen could show the engine strip. The PFD has the terrain mode turned on. Choosing the screen is one button push away.

















VFR Friendly


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.


Above the green arc shows where the airplane will be when it reaches a pre-selected altitude (ground level in this case). Extended centerlines make it easy to line up on the correct runway, and is essential at night.


Obstacle Alerting


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-the PFD. They appear in the same location out the window as they appear on the screen. Simple, and potentially life saving.






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-performance airplanes, such as RV’s, Lancairs, and all pushers, where engine cooling can require some pilot technique to manage. It leaves no doubt which way temperatures are headed.


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.


Simple Operation


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-in-the-sky guidance for the synthetic approach still delivers the sense of reality necessary to make any approach easier and more precise.






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-alone AHRS, is built into the Sport.  Read more about the latest generation of AHRS technology here.



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.


Autopilot Ready


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. Read more here.


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-interface. It may be remotely mounted, just like any data collection device, but it  can also be mounted in the instrument panel as a primary or backup display of engine data. In tandem seating airplanes it can be used as an instrument for the rear seat. Engine limits can be set in the EIS and can be used to drive its own warning light, even when remotely mounted.


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-in!)


Choose your screen size


The Sport SX is available in 6.4” and 8.5” screens, with the 8.5” being the most popular. Both feature the sunlight-readable LED backlit screens. The compact design allows two 6.5” screens to be stacked in the typical panel, such as an RV. The 8.5” screens can be mounted side-by-side in front of the pilot. The SX works great alone or with another SX or Mini.

“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!”
