As a result of the new RNAV procedures at Detroit and Cleveland, a new LOA with ZID will get effective as of September 22, 2018. It can be found on our website by signing in and navigating "Controllers"--> "Documents". I would like all center certified controllers to read and understand this new LOA, since it includes some changes on our side as well. Expect more updated LOAs to be released within the next week or so.
If you have any questions, let me know.
