The FlightGear ticketing system is moving over to GitLab. See https://gitlab.com/groups/flightgear/-/issues to report issues in the simulator itself.
(Tickets will be migrated over automatically, so this system is now read-only.)
To report issues with aircraft, please try to contact the maintainer of the aircraft. Reporting aircraft bugs here will usually mean the problem does not get fixed.
Hint: To find tickets you've submitted, click here (or the "My Tickets" search in the left sidebar)
