What is the minimum requirement for a Biannual Flight Review (BFR) according to the FAA?

The correct answer indicates that the minimum requirement for a Biannual Flight Review (BFR) according to the FAA is 1 hour of flight and 1 hour of ground training. This aligns with FAA regulations, which stipulate that a pilot must receive a review consisting of at least one hour of ground training covering various subject areas, such as regulations, weather, and flight maneuvers, followed by one hour of flight training where the pilot demonstrates their proficiency in flying. This structured approach ensures that pilots maintain their skills and knowledge over time, promoting safety and competence.

This option also reflects the importance of both theoretical and practical components in pilot training, as the ground training provides a foundation for decision-making and understanding of regulations, while the flight training focuses on the pilot's actual flying skills and ability to execute maneuvers safely.
