SEB-34-07 Revision 1 - September 14, 2021 Page 9 Single Engine OWNER ADVISORY SEB-34-07 TITLE NAVIGATION - GARMIN G2000 SYSTEM SOFTWARE UPGRADE TO VERSION 1308.10 TO: Cessna Aircraft Model T240 Owner REASON This version 1308.10 software service bulletin provides an upgrade that includes the following changes: • 60/40 PFD Display Functionality:The 60/40 PFD Display Functionality is the display of primary flight instrumentation on the 60% left-hand side of the GDU 1400 PFD, and the display of a Multi-Function Window (MFW) on the 40% right-hand side of the PFD. The functionality of the Multi-Function Window is identical to that of the MFD. • Transponder Mode Select:In previous software, if the transponder mode was manually changed relatively quickly, the mode would temporarily change and then revert back to the previous mode. In this software update, this issue has been addressed so that even relatively quick manual mode changes are now possible and are locked into the transponder. • Flight Level Change Control Wheel Steering:In previous software, application of CWS while utilizing FLC mode would not synchronize the Autopilot/Flight Director to the new reference, and instead would follow the previously selected airspeed reference. This software update enables the CWS to set a new reference. • Stall Warning Fail CAS Message:This software update is enabling the STALL WARN FAIL CAS message with the baseline software along with adding a Software Configuration Option “DISABLE STALL WARN” to disable the CAS message for aircraft prior to Flight Into Known Icing (FIKI) production. All production aircraft delivered after the introduction of FIKI (S/N 2049 and later) will have a stall warning computer installed and will require the STALL WARN FAIL CAS message support in the baseline software. Group A aircraft covered by this bulletin do not have a stall warning computer installed and will require that the "DISABLE STALL WARN" configuration option be installed. • Engine Tach Timer Reset:The 1308.09 version of the software caused the engine tach timer to reset when the SD card was used to load system software onto the system (during maintenance). The 1308.10 version prevents the tach timer from resetting when the software is loaded. COMPLIANCE DISCRETIONARY. This service document can be accomplished at the discretion of the owner.
