The "Problem" is not Fixed, i get 98% CPU-Load.I am not sure if Planeplotter software developers have removed the bug or it is still there.
You can check using command "top", check CPU % of Planeplotter, then issue command to restart dump1090, and check again the CPU usage of Planeplotter. If it does not jump to above 90%, then the bug has been removed by Planeplotter RPi feeder Developers
That is not enough. To fix 98% cpu load bug, you will need to add line given below in ppup1090.service file:Next i will implement from https://discussions.flightaware.com...tter-site-directly-from-raspberry-pi/37538/27
An alternate (and better) method to start ppup1090 at boot is to create ppup1090.service file and enable it, so that ppup1090 is started by systemd instead of rc.local.
