Yes, you need to renew your PPL (Private Pilot License) periodically to keep it valid. To do this, you must complete a flight review every 24 months with a certified flight instructor. This review involves demonstrating your flying skills and knowledge of regulations. If you fail to complete this review within the time frame, your PPL may become inactive, and you might need additional training or testing to regain your privileges. Always ensure you meet the renewal requirements to continue flying legally and safely.
