With the imminent arrival of Concorde for MSFS, it would be a nice touch to add the old Concorde flight corridors (North Atlantic tracks) into the navdata and the Navigraph charts.
I have the waypoint/reporting positions for the three corridors Sierra Mike, Sierra November and Sierra Oscar. But it would be tedious to have to define these in MSFS each time I wanted to plan a flight.
