Version 21.1.1 of the Infinite Flight ATC Manual is now live and can be accessed here.
For pilots the only notable change is the removal of the “Severe Weather” ATIS remark from 4.2.1.
As part of the changes based off feedback from both pilots and controllers, the minimum controlling times have now been reduced to 30 minutes for all facilities. This rule is in place to ensure that pilots receive a good and consistent service.
The rest of the changes are all either minor or internal changes, you can view the entire change-log on this page.
