Preserving your View
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. To preserve this view, insets are used. The pilot-

Dedicated Remote Avionics Controls
The HXr expands your options by letting you remotely control as much or as little of your radio rack as you desire. The dedicated controls and simple operation makes this immensely practical, leaving your valuable panel space available for other uses. Remote up to 2 Com radios, 2 Nav radios, transponder, intercom, and audio panel. Panel mount radios can also be conveniently tuned. The HXr works with a variety of leading avionics manufacturers, so you will never be locked into one brand for your interfacing remote avionics. Remotes, such as the Trig TT22 transponder, can offer a cost savings by negating the need for a dedicated control head.
As with the HX, the HXr allows you to use your Android device for extensive touch-

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 it. Read more about the latest generation of AHRS here.

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. With 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.
As a practical matter, the EGT Time history is our favorite way to get reassurance of normal engine operation. Now whenever you fly over water, or at night, you will have the confidence that only comes from seeing a history of steady EGTs. It reduces anxiety and adds confidence to any flight.
CHT time history proves useful by making the trend obvious. This is especially useful in high-
When it comes to flying economically, the specific fuel consumption (SFC) display is just the ticket. Its measure of engine efficiency confirms when you have leaned properly and tells you when you need to lean again. Without SFC, it is nearly impossible to know if re-
Miles per gallon through the air makes it easy to detect changes in efficiency of your airplane due modifications for drag reduction or if you just forgot to fully retract your flaps. Miles per gallon over the ground lets you optimize your economy while accounting for the wind.
Simplified screen layouts and more buttons also allow for simplified operation. Menus are practically identical for the PFD and map screens. New to the EFIS and not sure what a softkey does? Go ahead-
When on the ground or in calm air, practically any pilot interface will work. Introduce turbulence and the story changes. To operate an EFIS in such conditions, the pilot must be able to position his fingers on the control (knob or button) without activating it. Activation of the control can then take place with assurance the intended operation will be performed. This is why the HXr does not have a joystick type control. It has high-
Generous Connectivity Options
Like our HX models, the HXr includes 8 serial ports in and out (one configurable as RS422), dual ARINC 429 in, ARINC 429 out (optional), and dual USB ports. Multiple display units are coupled via Ethernet. Analog interfaces include 8 analog inputs and 8 discrete outputs. We have the interfaces for your needs now and into the future.
Redundancy will not be compromised in panel designed around the HXr. The extensive interfacing and processing power of the HXr allows dual inputs for attitude/air data, while still accommodating dual GPS and nav/com into every HX display unit. Automatic cross-
The HXr includes full autopilot functionality. Just add GRT servos and you are on your way to a fully automated cockpit. Like all GRT EFIS systems, it can also control an external stand-
Already own an autopilot? Just wire it to the HXr, and the HXr will couple it to all your navigation sources.

Control Radios and Flight Plans with Your Android Phone or Tablet
Install an optional Bluetooth dongle and connect with your Android phone or tablet using our GRT REMOTE App for Android. Fully control your connected radios, create & edit active flight plans and view the flight instruments all on your Android tablet or phone–perfect for the backseat co-
Free Database and Software Updates
Navigation database updates are provided free for all US territories. Software updates are also free. All GRT equipment includes bootloaders, allowing them to be updated via the HXr without removing them from the airplane.
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 HXr software support for the following equipment:
(If there is a device that you do not see on this list and you would like the HXr 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 HXr, future growth is built-

Easy Upgrade Path from Older Horizon Systems
The HXr shares the same wiring as our Horizon HX systems, and is 100% compatible with the Horizon HS and WS systems. User settings can be backed up and transferred from their legacy equipment into a new HXr, making upgrading even easier. Click here for upgrade price list.
