For holders of pilot certificates issued by the United States Federal Aviation Administration a flight review (previously the FAA referred to this as a biennial flight review, usually abbreviated BFR) is a review required of every active holder of a U.S. pilot certificate at least every 24 calendar months. The flight review consists of at least 1 hour of ground instruction and 1 hour in-flight with a qualified flight instructor, although completion of any Phase of the FAA WINGS program also satisfies the requirement for a flight review.

FAR 61.56 specifies that the review must include:

1. A review of the current general operating and flight rules of FAR 91; and
2. A review of those maneuvers and procedures that, at the discretion of the person giving the review, are necessary for the pilot to demonstrate the safe exercise of the privileges of the pilot certificate.

Before being able to act as pilot in command (PIC) a pilot must have completed a flight review within the previous 24 calendar months. The FAA and instructors are quick to point out that it is not a test. There is no pass or fail criteria, although the instructor giving it can decline to endorse your log-book that a flight review has been completed.

A flight test (administered by an FAA representative or Designated Pilot Examiner) that leads to a new certificate or rating may be substituted for the flight review. Completion of a proficiency check administered by a check airman (typically air carrier pilots) can also be used.
