How long is a first-class medical good for a pilot under 40 years of age?

• A. 6 months
• B. 12 months
• C. 24 months
• D. 36 months

Answer: (B)

The main idea here is the duration of a first-class medical for pilots who are under 40. A first-class medical, which is the highest level of medical certificate used for airline-transport pilots, is valid for 12 calendar months for someone under 40. This means you’d need a new medical evaluation after that 12-month period to continue exercising the privileges that require a first-class certificate. The other time frames don’t apply to someone younger than 40—shorter durations come into play once age 40 or older, so 6 months, 24 months, or 36 months aren’t the correct durations in this case.
