How long is a Class 3 medical certificate valid for a pilot under 40?

A Class 3 medical certificate is valid for 5 years for pilots who are under the age of 40. This regulation is part of the FAA's medical certification requirements, designed to ensure that pilots maintain the necessary health standards to safely operate an aircraft. After turning 40, the validity period decreases to 2 years, reflecting the increased health monitoring needed as pilots age. Understanding the validity periods for different classes of medical certificates is essential for maintaining compliance and ensuring that pilots can legally carry out their duties.
