Ok, I think I understand. But. In Sweden at least, ATC operating hours at towered airports is more and more concentrated to departing and arriving scheduled traffic with the tower being closed in between. Being based myself at a non towered airport I would believe that a large portion of my flying would be from one uncontrolled airport to another and the rest being flights either originating or terminating at an uncontrolled airport. How much would this affect the usability difference between the EIR and the full IR?
