Downloading AF-6600/AF-5000 System Logs for AFS Review
The EFIS system logs contain a chronological record of events related to the function of the EFIS and of its attached components. Issues that may develop with your EFIS or other avionics can often be diagnosed by reviewing the system logs. Therefore, these logs will usually be one of the first things AFS requests when you contact us regarding problems with your avionics. Here is how to download system logs and send them to AFS for review.
Downloading logs from EFIS
- Make sure you have a USB drive plugged into the EFIS (using the USB drive that has your map and high res terrain files is fine)
- Go to SET > LOGS > SYSTEM
- Wait for system logs to copy to USB. File copy is complete when the / WRITING FILE / annunciator message disappears
- Turn off EFIS, remove USB stick, and plug USB stick into a computer
Sending system logs to Advanced Flight Systems
- Open the USB stick in your computer’s file explorer app. Look for the SYSLOG_7xxxx_yymmdd.ALS file (and not the similarly named .ATZ file)
- Email this file as an attachment to
- AFS will review the logs and respond to your email.
- In certain circumstances AFS may request what we call the full system logs, which means the SYSLOG_7xxxx_yymmdd.ATZ file (and not the .ALS file). The full logs contained in the .ATZ file are much too large to attach to an email. If AFS requests the full system logs, open a web browser and navigate to https://www.advancedflightsystems.com/file-upload.php
- Fill out the form with your contact information.
- Click the “Add Files” button on the webpage, navigate to your USB stick, and select the SYSLOG_7xxxx_yymmdd.ATZ file
- Click the “Send” button to upload the file to the AFS server. The file is very large and may take several minutes to upload depending on the speed of your internet connection. Do not close your browser tab or web browser until the page notifies you that the file upload is complete.
