SUBJECT:
GDL 88 Software Upgrade to System Software Version 3.00
CERTIFICATION
AUTHORIZATION: TSO Authorization (see Approval section for details)
REV B:
Added a note describing CSA failure indication.
PURPOSE
This Service Bulletin announces the availability of GDL 88 System Software Version 3.00 and supersedes
Software Service Bulletin 1371.
GDL 88 System Software Version 3.00 contains the following changes from Version 2.06:
•
•
Required update to improve 1090 MHz Mode S Extended Squitter receiver message processing
Support for Flight Stream 110 and Flight Stream 210.
DESCRIPTION
This Service Bulletin describes the process for upgrading the GDL 88 Series Unit’s System Software to
Version 3.00.
NOTE:
After updating to GDL 88 System Software Version 3.00, an indication that the CSA
(Conflict Situational Awareness - traffic alerting) functionality is failed will appear when the
aircraft is not moving (has no current GPS track) and there is no source of aircraft heading
provided to the GDL 88. In fixed wing aircraft, this typically occurs only when the aircraft is
on the ground and is not moving. The CSA failure indication will clear when the aircraft
begins moving again. The CSA failure indication when there is no current GPS track and
no source of aircraft heading will be addressed in a future software release.
APPROVAL
TSO authorization does not provide installation airworthiness approval. Separate installation
airworthiness approval is required for type certified aircraft.
GDL 88 Software Version 3.00 is TSO approved. The change is major per 14 CFR 21.619.

reader. See the Material Information section for applicable SD card specifications.
4) Run the executable file that was downloaded and follow the prompts on the screen to create the
loader card.
5) After the card has been created, eject the card from the card reader. The GTN LRU Update Tool
loader card is now ready to use.
NOTE:
The following Software Installation procedure must be completed twice before the full
update will be complete.
Software Installation:
