Federal Aviation Regulations Practice Test

To determine the expiration date of a First-Class Medical Certificate granted to a 23-year-old pilot on October 21 of the current year, one needs to consider the validity period of medical certificates as outlined by the Federal Aviation Administration (FAA).

For a First-Class Medical Certificate, which is typically applicable for airline transport pilots, the validity period differs based on the age of the pilot at the time the certificate is issued. Since the pilot is under 40 years old, the certificate will remain valid for 60 months (5 years) from the date of issuance.

Given that the certificate was issued on October 21 this year, adding five years to this date leads to an expiration on October 21 five years later. Thus, the certificate will expire on October 21, 2026.

This is a key point of understanding the different validity periods associated with medical certificates and recognizing how they apply based on the age of the pilot at the time of issuance. Therefore, October 21, 2026, correctly reflects this calculation.
