How often must a pilot undergo a medical examination?

The frequency of medical examinations for pilots is determined by the class of certification they hold. For example, first-class medical certificates require an examination every 12 months for pilots under the age of 40 and every 6 months for those 40 and older. Second-class certificates require an examination every 12 months irrespective of age. Third-class certificates have a similar requirement, with examinations occurring every 60 months for pilots under 50 and every 24 months for those 50 and older. This variability in examination frequency based on certification class and age makes the answer that specifies a range of 1 to 5 years, depending on the certification class, the correct choice.

While other options may suggest more frequent or less frequent examinations, they do not accurately reflect the regulatory requirements as defined by the Federal Aviation Administration (FAA). Therefore, understanding the medical certification requirements helps pilots maintain compliance and ensures their capabilities align with safety regulations.
