All GDL 88 models with Software Version 3.00.
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.
No pilot action is required.
