How often must a flight review for commercial pilots occur?

For commercial pilots, a flight review must be conducted at least once every 24 calendar months. This requirement ensures that pilots maintain their flying proficiency and are up-to-date with the operational standards and best practices in aviation.

This interval is set by the Federal Aviation Administration (FAA) regulation, which aims to enhance safety by encouraging regular evaluations of a pilot's skill set, knowledge of regulations, and ability to handle potential emergency situations effectively. By requiring the review every two years, it strikes a balance between ensuring proficiency and allowing a reasonable period for pilots to gain experience and knowledge without being burdened by overly frequent assessments.

The incorrect options provide intervals that are either too short or too long, failing to align with the established regulatory framework for maintaining pilot currency and competency.
