Airway “A2” in Europe has a directionalrestriction over the whole route such that it can be flown only one direction. For example, airway “UR975” inNorth Africa has more complicated directional restrictions within the list of airway waypoints. That is, eachwaypoint may have its own conditional route in relation to another waypoint.In the US, airways that are “one-way” for specified hours of operation are not uncommon. These airwaysare always bidirectional in the system database.The system only allows correct airway sequences to be inserted. If the pilot subsequently inverts the flightplan, the system inverts the airway waypoint sequence and removes the airway header.
