I’ve been feeding to FA since a few weeks now. Since end of October, my statistics show a downward trend. Since about 2 weeks I have started to record data into VRS 24/7.
When I compare the statistics of FA and the output of the VRS database, I see huge differences in the number of flights reported as well as the number of positions.
I assume that there is some selection performed on what message are considered for FA usage, but I would be interested in finding out if you have made the criteria stricter since end of October?
