This section contains software in the development or testing stage for customers interested in testing new features before a final release. The software below may be incomplete or have unexpected behavior. Never use in instrument conditions or other situations where EFIS failure or unexpected behavior will affect safety of flight.
The most current release of the AHRS software is included in the Display Unit update files. Most GRT EFIS users will never need to use this page. However, there are times when customers request AHRS-only updates or would like to try beta testing new AHRS software.
All versions of the GRT EFIS with a MAP page (except Mini) contain a checklist function (with recent software). The checklists must be created on a computer in plain text format and loaded into the EFIS as CHECKLIST.TXT. A text editor such as Notepad will work.
Emarit Ranu’s Excel-based Flight Data Analysis Tool can open demo files in Excel to make graphs, compute statistics, and show flight paths on Google Earth.
Carl Morgan’s Demo File Decoder can load flight data into a spreadsheet & plot GPS data on Google Earth.
Copy the files inside these ZIP files to your USB memory stick to play back some recorded approaches and weather on your EFIS. *Note that any demo file can be played on any GRT EFIS, regardless of which model it was recorded on.
Allows EIS recorded data to be decoded in spreadsheet form. Record on your EFIS memory stick or to a laptop and decode the file with this software. Version 11 3/09/2015
The GRT Remote App offers many tools to ease pilot workload for flight planning, radio tuning and offers support for the Hudly Heads-Up-Display. It is also a unique and simple solution for back-seat flight instruments and controls for radios and flight planning. Version 2.3.0 Updated 1/05/2017
Version 5 adds support for more types of compliant GPS data and supports sending air data for ADS-B air-ground switching by setting Squat Switch to AHRS and GPS data (requires display software update). Version 5 released 7/6/2017
Note: One Jeppesen data subscription can be shared among all GRT EFIS screens in the airplane. Database sharing is supported by EFIS software versions 2a (HXr), 6a (HX), 10 (SX), all Mini, all EX, and newer versions.

These “mini-manuals” explain how to install and set up popular devices and avionics that work with GRT EFIS systems. You can pick the ones you need, print them out, write notes all over them and store them with your aircraft’s electrical system diagrams. Check back often for new releases or email us for special requests. We often create new supplements based on customer requests and then post them here for everyone’s benefit.
Note: Only Horizon 10.1 and HXr EFIS systems are capable of full remote control of com radios, nav radios, and intercoms.
