This STC update adds approval for the installation of the GI 275 Multi-function Instrument into Airbus AS 350 BA, AS 350 B2, and AS 350 B3 Series rotorcraft. This STC update also adds approval for GI 275 Software Version 2.60 which provides the following updates:

NOTE
Database sync routing is affected by this change. Systems with GTN™ (v6.72 or earlier) or GPS 175/GNC® 355/GNX™ 375 (v3.20 or earlier) interfaced to G500(H)/G600/G700 TXi (v3.50 or later) or GI 275 (v2.60 or later) no longer support database sync. Databases will need to be loaded onto each GTN and GPS 175/GNC 355/GNX 375 unit. This limitation will be fixed in future GTN and GPS 175/GNC 355/GNX 375 software versions.
