AI Traffic and Liveries

read your comment with interest - notice you mention parked aircraft with custom liveries - which I am definitely getting - never checked but I had assumed these would eventually start and become “real traffic” - is there a separate setting for controlling amount of parked aircraft?
Also by way of update finally managed to get some “real traffic” by selecting “live traffic” - is there any kind of setting to control amount of this or is it fixed depending what date you select? - presumably if you select a day in
2019 it should give you more activity than in 2020/21 (due to COVID)?
Note I still think the level of activity I was getting at heathrow for example was very limited (3 or 4 planes!)
