I found out yesterday late that this does not have one. I had a major problem with the avionics, as I could not switch anything on... I restarted x-Plane 11...
I can only guess that there is some activation routine of the licence? It worked the second time around: So, install aircraft and run x-plane 11, activate licence after entereing/pasting code, shut sown x-plane. Restart and load the aircraft for a new flight. This is where I thought everything should work, but it didn't. It wasn't until I restarted x-plane again and reloaded the Arrow that everything worked as it should.
Just to let you know...
