G750 Simulator
G750 Simulator


There are lots of ways to learn how to use the GTN 750. Here’s the best way to master it.

The G750 Simulator is high-fidelity G750 avionics simulation software that integrates with Lockheed Martin® Prepar3D™, Microsoft® Flight Simulator X, or Laminar Research X-Plane. It provides a far more immersive training experience than a stand-alone part-task trainer.





The software is modeled after the Garmin GTN 750 and is a nearly one-to-one simulation of the real GTN 750 software. Features include:




  • A simulated touch and drag interface that allows you to interact with the system, graphically edit flight plans, and much more using the mouse cursor (or a touchscreen monitor)




  • Full COM/NAV receiver integration




  • A WAAS-certified GPS
  • A multi-channel ILS/VOR with localizer and glideslope receivers
  • Built-in WAAS navigation capabilities to fly LPV "glideslope" approaches without reference to ground-based navaids of any kind (providing vertical and lateral approach guidance into thousands of U.S. airports previously inaccessible in IFR conditions)




  • Updateable, built-in terrain and navigation databases that contain location reference for all airports, VORs, NDBs, Intersections, Flight Service Stations, published approaches, SIDs/STARs, Special Use Airspace, and geopolitical boundaries
  • A worldwide database of roads, rivers, cities, oceans, lakes, etc.
  • A worldwide obstacle database and obstacle alerts




  • A high-resolution moving map display with full data integration (including navaids, airports, cities, highways, railroads, rivers, lakes, coastlines, and more)
  • High resolution terrain maps (worldwide)
  • SafeTaxi® detailed airport information on the moving map (US and Europe Only)
  • FliteCharts® electronic AeroNav terminal procedures charts (US Coverage Only)




  • ADS-B system with alerts
  • Terrain proximity warnings
  • Terrain Awareness and Warning System (TAWS-B) audible alerts (North and Central America only)


Autopilot Integration


  • Integration with standard autopilots that accept roll-steering commands to automatically fly your aircraft through holding patterns, procedure turns and other position-critical IFR flight procedures


The software simulates the features and functionality of the real GTN 750 so accurately that we didn’t want to re-write the real manual. Thus, we encourage you to use Garmin’s GTN 725-750 Pilot's Guide as a reference for learning to operate your G750 Simulator.



The G750 Simulator software will interface with the default aircraft in Prepar3D v3 or v4,  and X-Plane, or with any add-on aircraft that you’ve installed. And because the software is a stand-alone application that merely interfaces with Prepar3D and X-Plane, it can be run on a separate PC connected to the flight simulation over a network. When configured this way, the GTN 750 simulation won't slow down the flight simulation's performance.


The software is highly configurable. Options include:




  • Maintaining the aspect ratio when resizing the window, and saving the window size and position between sessions
  • Displaying or hiding the G750 Simulator window frame
  • Enabling or disabling sounds like audible warnings and alerts, and clicks when pressing buttons and turning knobs
  • Enabling or disabling “Active Mouse” and "Invert Mouse" functions that makes the G750 Simulator easier to use with a mouse
  • Selecting different “Ownship” symbols




  • Selecting which core the G750 Simulator will run on when using a multi-core PC


Com and Nav


  • Selecting which Com and Nav radios the G750 Simulator will control
  • Selecting which method (Nav or Heading) the G750 Simulator uses to control the aircraft’s autopilot
  • Enabling or disabling “Link Course” and “Auto-Course” functions that simulate G750 messaging and automatic course features
  • Switching between following GPS flight plans created in the G750 Student Simulator, or in the flight simulation GPS




  • Switching between the Terrain Proximity Warning System and TAWS




  • Selecting whether the GTN 750 Student Simulator fuel flow and fuel quantity values are read from the flight simulation, or entered manually


Integration with LJCockpit's Hardware GTN Stack
