As stated above with simple traffic installed as per the instructions I have plenty aircraft sitting at the gates with the proper liveries but no movement. I understand that simple traffic only displays what msfs gives it. It doesn't matter if I set it to ai offline or live traffic it's the same thing. I have tried both settings at various busy airport's in Europe and USA but still no movement. For clarity if I set for live traffic and click on show traffic at airport on the create flight map it shows lots of arriving and departing flights, I then click fly now and leave it for a while up to 30 minutes but still only static traffic nothing moveing. As stated my settings are exactly as stated in the manual. Any clues to what could be the fix for this. Thanks.

For starters  I would just move the Simple Traffic folder from the community folder and see what the default sim does. As you say, we only make traffic look different do not spawn it in any way.

 

Of course keep in mind that on a smaller airport you might only see one or two aircraft moving every hour.

I have been at this for a while and found a post that it was caused by navigraph. I uninstalled navigraph not knowing there was a special way to do it. Re installed it and I now have lots of traffic moving and taking off but unfortunately no landing traffic. I did have landing traffic last week so no idea whats happening, i guess its something to do with msfs. Thanks for reply.

We simply do not see any way Navigraph could cause this.
