What is the validity period for a first-class medical for a pilot under 40?

The validity period for a first-class medical certificate for a pilot under 40 is indeed 60 months, or 5 years. This means that if a pilot who is under the age of 40 passes their first-class medical examination, they are considered medically qualified to act as pilot-in-command for that duration.

Medical certificates serve to ensure that pilots meet the necessary health standards to operate aircraft safely. The longer validity period for younger pilots reflects the lower likelihood of health issues affecting their ability to fly within that age group. Therefore, it is essential for pilots to be aware of their medical certificate's expiration, as operating with an expired certificate can have legal and operational consequences.

Pilots over 40, on the other hand, are required to renew their first-class medical certificates every 12 months, highlighting the increased scrutiny of medical conditions that can potentially develop as a person ages.
