Software Description
AHRS Software 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.
Checklist (Example) 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.
Demo File Decoding and Analysis

SavvyAnalysis.com analyzes engine data as a service.

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.
