Software Updates

Note: If you do not know which GRT system or which software version is installed in your aircraft, read the initial boot-up screen when you first power on the EFIS, before you press “ACCEPT.” The model designation of the EFIS, along with the installed software version, is displayed at the top of the page.

WARNING: While we test new software to the best of our ability before release, we cannot guarantee perfect function in individual experimental aircraft. Fly several hours in VFR conditions to verify proper operation of ALL EFIS features before attempting IFR flight with any new software. Contact GRT if you encounter problems with new software. Operation of aircraft using new software is at your own risk.
