If a pilot over 40 has a 1st Class Medical certificate, how long is it valid?

The validity period for a 1st Class Medical certificate for pilots over 40 years of age is 6 months. This is established to ensure that pilots maintain the necessary medical standards, particularly as certain age-related health concerns can arise.

For pilots under 40, a 1st Class Medical certificate is valid for 12 months, reflecting a longer period without the increased risks associated with aging. However, after turning 40, the validity is shortened to 6 months, requiring more frequent evaluations to ensure that their health is suitable for the responsibilities of flying. This is an important aspect of aviation safety, as it helps to mitigate risks related to medical conditions that may affect a pilot’s ability to operate an aircraft safely.
