If a pilot fails to maintain their flight review, what are they permitted to do?

A pilot who fails to complete their flight review is prohibited from carrying passengers. The flight review is a crucial component of maintaining currency and ensuring that a pilot is adequately prepared for flying responsibilities, which includes the safety of any passengers. This requirement is in place to promote safety in aviation by ensuring that pilots regularly demonstrate their flying skills and knowledge.

While pilots may still operate their aircraft solo or with an instructor to regain their currency, they cannot legally fly with passengers until they have successfully completed their flight review. This policy helps to reinforce the importance of regular training and evaluation, as flying with passengers necessitates a higher level of proficiency and responsibility. Therefore, option C is the only accurate representation of what a pilot is permitted to do if they have not met the requirements of a flight review.
