How could I display a current, running log of my FlightAware / PiAware software? I know you can see the last few lines of the log in “My ADS-B” Control Panel, but I would like to enable a real-time, running log… if that is possible. Thanks for any feedback.
Either locally access the RPi or use SSH/Putty:
For Beginners - How-to SSH to RPi - Setup Putty in Windows
sudo journalctl -f
Or if you only want piaware because the log is being spammed by something else:
sudo journalctl -f -u piaware
Give this command
cat /var/log/piaware.log
To issue commands:
Either
Connect a mouse, monitor, and keyboard to RPi and use its terminal
OR
SSH using Terminal (Mac)
SSH using PuTTY (Windows)
Thank you very much!
Above command outputs log, which keeps on updating every 5 minutes. It is dynamic. 
cat /var/log/piaware.log displays log up to the time command was given, but do not update after that point in time. It is static.
To follow a file while it is being updated, you can use:
tail -f /var/log/piaware.log
