I have a GRT EFIS. How do I customize the 'Flight Data Viewer' to match my installed equipment?

Run the 'Flight Data Viewer' and from the menu select 'Options'.
Update your preferences as suggested below.

Data Folders

Data Folders Options
Notes: Only select the "GRT Binary & CSV Data Format".

Enter the drive where you will insert the SD card removed from your EFIS.
Enter the folder path where you would like to store your extracted flight data files. The default is appropriate for most situations.
If you check 'Create Yearly Subfolders ...' folders named with the flight year (ex: 2020) will be created and your flight files will be stored in the correct folder.


Units Options

Data / Equipment Enables

Data/Equipment Options
The most important items on this tab are the number of CHT & EGT probes. The 'Starting CHT Probe Port' and 'Starting EGT Probe Port' entries are not used for GRT devices. Use the default value.
The cylinder descriptions are displayed on the CHT & EGT graphs.
The 'Twin Engine' option is not valid for GRT devices.

GRT Aux Inputs

These settings are only used if you are extracting data from GRT .CSV files. These files contain six columns 'Aux1' - 'Aux6'

You can map these columns to the following values in the Flight Data Viewer:
  • Left Fuel Level
  • Right Fuel Level
  • Manifold Pressure

If your installation has other equipment attached to these general aux ports send us an and request that it be supported.
