When I generate a flight plan from CYYT that crosses the atlantic using a NAT track, where the initial point of the NAT track is reached before the aircraft can reach ToC, the generated flightplan cannot be loaded into the Fenix A320, and it also shows an erroneous ToC waypoint when imported into Navigraph Charts.
This is an unusual case since the vast majority of flights would have reached ToC long before reaching the NAT track.
