What must a pilot prove to maintain privileges after changes in class ratings?

To maintain privileges after changes in class ratings, a pilot is required to demonstrate successful completion of a flight review. This flight review is mandated to ensure that pilots maintain a high level of proficiency and are up-to-date with regulations and operational procedures relevant to the aircraft they intend to fly. The flight review consists of a minimum of one hour of flight training with an instructor and one hour of ground training, encompassing various maneuvers and procedures that the pilot must effectively perform.

While continuous flight experience in an aircraft type and meeting recent experience requirements are important for piloting safely and competently, they are not the specific regulatory requirement established for maintaining privileges after a class rating change. The flight review specifically is emphasized in regulatory guidelines as a means to ensure ongoing pilot competence.

Ultimately, the successful completion of a flight review serves as a comprehensive assessment of the pilot's current skills and knowledge, which is fundamental for safety in aviation operations following any updates to class ratings.
