What type of flight review is required for each recreational or private pilot?

A biennial flight review is a requirement for both recreational and private pilots as per FAA regulations. This review must be conducted every 24 calendar months and is designed to ensure that pilots maintain their flying proficiency and are up to date with current operating standards and aviation regulations. During a biennial flight review, pilots typically undergo a combination of ground instruction and flight training to reinforce their skills.

The specific frequency of this review helps ensure that pilots are regularly evaluated and can effectively operate an aircraft, which is essential for safety in aviation. The other options suggest more frequent reviews, such as annually, semiannually, or quarterly, which are not mandated by the FAA for recreational or private pilots. This biennial requirement strikes a balance by reinforcing skills while not imposing excessively burdensome frequency, thus allowing pilots to continue enjoying flying while remaining competent and safe.
