Why GRT Avionics?

We’ve been around…

We’ve been building electronic flight instrumentation since 1991 and pride ourselves on offering a full range of feature rich EFIS systems suitable for a variety of aircraft. Ultra-lights to twin engine Velocity V-Twin’s and even turbine powered aircraft – aircraft owners choose GRT Avionics because of accuracy and reliabilty, our dedication to innovation and excellent tech support.

Compatibility

Every builder has his or her own taste when it comes to devices such as weather & traffic information, radios, transponders, and GPS units. We strive to give builders a choice when it comes to third-party equipment and have an extensive list of equipement that we can work with.

Help is just a call away

Even experienced builders run into problems sometimes, so we are just a phone call or email away. Our experienced technicians are happy to assit you in troubleshooting problems with your installation or helping you with features that you don’t quite understand. We’re here for you…

EFIS Displays

Horizon HXr EFIS

One look at the HXr and you sense the situational awareness provided by the large screen and its wide field of view. A view that feels almost as natural as looking out the window and reaches out 30 miles. The pilot-selectable insets provide maps, traffic, engine monitoring, weather, traffic alerts, custom checklists, and even geo-referenced sectionals or en-route charts. Insets are also the key to keeping the PFD view unchanged so that your instrument scan remains unchanged. Remote control up to two Com radios, two Nav radios, transponder, intercom, and audio panel. The HXr works with a variety of leading avionics manufacturers, so you will never be locked into one brand for your interfacing remote avionics.

All HXr packages include an external Adaptive AHRS and wiring harness. Touchscreen available for 8.4″ and 10.4″ HXr for an additional $400 per display.

Horizon HX EFIS

The HX is a no-compromise EFIS with a compact 6.5” screen. It is built around a high speed processor that typically operates at 20% capacity while providing a 30-mile synthetic vision view. Interfacing is extensive to support dual redundancy for AHRS and radios.  The size allows two screens to be located in front of the pilot, even in compact cockpits. The HX is the ideal solution for the pilot that wants the comfort provided by redundancy, and who depends on this equipment to fulfill his missions.

All HX packages include an external Apdaptive AHRS and wiring harness.

Sport SX

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 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. A starting price of only $2600 makes this an unbeatable value for any the VFR or light IFR airplanes. All Sport SX systems include wiring harnesses.

Highly readable airspeed/altimeter tapes and rotating drum-style digital display. Free database updates for all US territory. Jeppesen databases available worldwide. Simple installation – power, ground and mount GPS antenna on your dash. Incorporates a full AHRS (internal) solution that does not require GPS or air data to provide attitude data. Engine display capable (requires EIS) on all models except Mini-B manufactured after 1/1/18. Bluetooth ready (dongle required).

Mini-GA

The Mini-GA is a portable electronic device especially designed for the certified aircraft that brings terrain and obstacles to your panel.   It is a reassuring reference when flying in instrument conditions, and greatly improves situational awareness, VFR or IFR.  Rotating drums and tapes are driven by GPS data, making GPS derived altitude and speed data, as well as their rate-of-change easily observable. Internal or external GPS navigation and steering data is provided on the PFD.  Highway-in-the sky guidance is provided to any runway in the database. The addition of the external magnetometer adds heading and winds for further situational awareness.

Autopilot

Every GRT Avionics display unit, from the first WS, through our HXr flagship, as well as the Mini-EFIS, is capable of performing as an autopilot control head.  Just connect one or two servos and we will fly you from just after takeoff, to just before touchdown.  We will couple you to your approach and fly you to your selected altitude…and much more!*

*Vertical autopilot functions are optional with some display units.
