If a pilot had a flight review on August 8 this year, when is the next flight review required?

The next flight review required for a pilot after one is conducted is due every 24 calendar months. This means that if a flight review is completed on August 8, it will be valid until August 8 two years later. Since the question asks for when the next review is required, the date would fall on or before the anniversary of the previous review, which is not limited to a specific day but encompasses the entire month of August.

Choosing the option that states August 31, two years later appropriately reflects that the pilot can complete their next flight review any time before this date, up to and including August 8 of the following two years. This timeline ensures compliance with regulations for maintaining currency and competence as a private pilot.
