How long is a medical certificate valid for a second-class medical holder over 40 years old?

A second-class medical certificate for a pilot who is over 40 years old is valid for 12 months. This duration is established by the FAA regulations to ensure that pilots maintain a level of medical fitness that is safe for operating aircraft. The frequency of medical examinations for older pilots reflects the recognition that health changes can occur with age, necessitating more regular evaluations to safeguard aviation safety.

For pilots under the age of 40, the validity extends to 24 months, which underscores a differentiated approach to the potential medical risks associated with aging. Therefore, in this case, the 12-month validity specifically pertains to those who are 40 years of age and older.
