I know that knowledge of traffic patterns is great for real-world operations. My point was that it does not seem like it was important enough to have in the map data, since it is already available from the FAA and in the sectionals. In retrospect, I am pretty sure that there is a misunderstanding here!
I was not aware that they had traffic circuit information available in a submenu, that is interesting! However, it is quite different from the European data where the patterns are published and rendered on the map directly. This is because here, the data includes more than just L/R traffic information - the patterns can get quite complex to avoid populated areas for example. Pattern vs. circuits is probably a good way to tell them apart conceptually.
As mentioned above, the “traffic circuits” that are mentioned here are not the same thing as the traffic patterns that are found outside of the US. Perhaps we can clarify this feature request slightly?
Do you want metadata about whether or not the traffic circuit around a certain runway is L/R? Or is there more graphical information about these traffic circuits somewhere, like in the image below?
