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 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.
