AirVenture Diary: More ADS-B, LSA Regs

More significant is that Garmins G5 electronic flight display can be installed as a legal STCd backup to the G500/G500 TXi flight displays. Believe it or not, previously this interface required an FAA field approval because the G500-series primary displays didnt include the G5 in the STC. The technical interface is expanded, too, and for the better. Any adjustments made to heading bugs, altitude select, airspeed bugs and baro settings are automatically synced from the G500 TXi or G500 displays to the G5. Flight director and autopilot mode annunciations from the GFC 500 can also be viewed across all displays, including on the G5. No, the G5 isn't approved for backup in Cirrus models. That means if you have a second-gen Avidyne Entegra or even G1000 Cirrus (or any other G1000 airplane) the G5 is off limits.
