On world #3423 the departure board for Paris Charles de Gaulle has a number of departures to Paris Charles de Gaulle showing a frequency of 0, they indicate as routes for my airline but the Flight Numbers don't match any numbers in my routes. I believe they may be Aircraft Maintenance Schedules appearing as routes. I've checked some other HQ airports of other airlines and they seem to have something similar e.g. OMA at Epperley Airfield.
