A Third-Class Medical Certificate issued on August 10 this year will be valid until when for a 36-year-old pilot?

The validity of a Third-Class Medical Certificate for a pilot is determined by the age of the pilot at the time the certificate is issued. For pilots under the age of 40, the certificate is valid for 60 months, which translates to 5 years. However, the expiration date is typically noted as the last day of the month in which the certificate is issued.

Since the certificate is issued on August 10, and the pilot is 36 years old, the certificate will remain valid until August 31, five years later. This means the correct interpretation of the expiration does not align with the choices presented but is instead calculated from the issuance and the valid timeframe based on the pilot's age.

Therefore, for a 36-year-old pilot, the Third-Class Medical Certificate issued on August 10 will indeed be valid until August 31, five years later, reflecting the full duration of validity for their age group. It is important to keep in mind that the option presented with 3 years is incorrect based on understanding the 5-year rule for pilots under 40, leading to the accurate calculation of the expiration date being August 31 of the fifth year after issuance.
