G500/G600 TXi PFD/MFD/EIS display systems installed using Approved Model List (AML) Supplemental Type Certificate (STC) SA02571SE are affected.
Optional: This STC Service Bulletin may be incorporated at the owner’s discretion and is not warranty reimbursable.
STC SA02571SE, Master Drawing List revision 5 includes G500/G600 TXi Main Software Version 2.30.
G500/G600 TXi Main Software Version 2.30 expands the TXi interface. The TXi can now be interfaced to a certified standalone G5 (via GAD 29/29B) without a GFC 500 autopilot system.
Previously, the TXi could only interface with a G5 when a GFC 500 autopilot system was also installed.
