For a pilot aged 40 or older, how long is a first-class medical valid?

• A. 3 months
• B. 6 months
• C. 12 months
• D. 24 months

Answer: (B)

For pilots aged 40 or older, the first-class medical is valid for six calendar months. This shorter window ensures more frequent health reviews for higher-level flight privileges. After six months, the first-class privileges are downgraded to second-class for the remaining six months of the year, even though the certificate itself may still be in use until its overall 12‑month date. So the best answer is six months.
