The Garmin GNS 430 revolutionized general aviation by combining COM, NAV, IFR GPS, and a moving map into a single unit, eliminating the need for separate COM and NAV radios, glide slope receivers, VOR converters, relay units, and annunciators.
Now Garmin is taking that concept even further with the new Garmin Axis 11.6-inch display. The system integrates a full EFIS display, COM, NAV, IFR GPS, a four-place audio panel, wireless connectivity, and USB charging into a single, fully TSO-certified unit.
For aircraft owners considering a glass cockpit upgrade, the Garmin Axis could become a very attractive solution. A Garmin GI 275 or G5 would still be required as a backup flight display. The FAA approved the Garmin Axis STC SA12406WI on 16 July 2026 and the EASA validation was approved in 22 July 2026 resulting in EASA STC 10090487 .
Based on the current certification information, it is also likely that a backup COM or COM/NAV radio will be required, depending on whether the aircraft is equipped for VFR or IFR operations.
After reviewing the STC installation manual we noted that the installation requirements reflect Garmin’s integration of G5/G3X technology (non-TSO) with GI 275/G500 TXi (TSO) system architecture. As with any integrated avionics installation, careful planning and review will be required. In an installation with a GFC 500 autopilot and a G5 flight display, the autopilot will continue to operate if the primary flight display fails. This level of redundancy is not available when using a GI 275 as the standby instrument. (Currently the GI275 is the only approved backup for the Axis display in EASA)
The requirement for a GAD 27 power stabilizer in 14-volt aircraft equipped with the GEA 24B Engine Indication System has been removed, making the GAD 27 optional.
